How to Avoid Malware, Virus, and Threats | Total Security Software

Tips to Avoid Malware, Virus and Threats

Whether you are accessing the Internet at home, at work, or at school, you should always take online safety seriously. Falling victim to scams, viruses, Trojans, malware, adware, and countless other problems is very easy to do, even if you know the risks.

Stay safe while following few basic rules. This guide covers the main risk areas and how to improve your personal cyber security when and where you access the Internet.

Use Antivirus Software

New viruses are released every day, and the best way to protect yourself is to use reliable antivirus software on your computer.

Antivirus software is constantly updated to protect your computer from the latest threats as they arise, and should be considered essential every time you go online.

It does more than protect your computer from viruses and malware. Depending on the product you use, it can also protect your privacy, prevent you from visiting unsafe websites, help you locate a lost device, and provide secure online storage.

What About Smartphones and Tablets?

The risks of virus and malware to devices are growing. As mobile devices become increasingly important to access the Internet, the temptation of criminals to attack them grows.

Today you can buy virus protection for your phone and tablet, as well as for your computer.

Be especially careful when downloading applications. Mobile and tablet apps are popular because they are so easy to use.

But while the apps in the Apple app store are generally safe because Apple controls the apps, the situation is different for Android devices. Always make sure to download original apps and read the reviews before downloading for any warning signs.

Keeping Your Online Accounts Safe

Viruses and malware are a true threat, and antivirus software is a must. However, many hackers and criminals believe the weakest link to urge what they want: human error.

The actions you take, or don't take, online can put you at risk, so it's important to follow safe online practices.

Passwords are one among the most important problem areas for everyday Internet users. Hackers can often crack passwords that are too basic, allowing them to access your personal accounts. To reduce the danger of this happening to you:

·       Use a different password for all your accounts
·       Make your passwords as long as possible
·       Don't use a password which will be easily guessed
·       Make your passwords completely random
·       Use a selection of letters, numbers, and symbols.
·       Never reveal your password to anyone.

The problem with doing all of this is that it makes passwords harder to remember, and this is where a password manager comes in.

Two of the best administrators are 1Password and LastPass, and these will store all your passwords securely and allow you to access them with a master password. This is one of the simplest ways to make sure your passwords are as strong as possible.

Password Protect Your Devices

On the subject of passwords, be sure to password protect your computers, phones, and tablets. It may take a bit longer to access them, but the added security is well worth it.

Then if someone steals your device, they won't be able to access your online accounts and personal information, giving you the opportunity to change your passwords and keep your online accounts safe.

Use 2-Step Verification Wherever Possible

Another step you can take to protect your accounts is to use two-step verification. Also called two-factor authentication (2FA). Many services now offer this, so use it whenever it is available.

To use 2-Step Verification, you will generally need to provide the business with your cell phone number. When you enter your password online from a device for the first time, the company will send you a text message containing a code.

Then insert the code to gain access to your account. This prevents anyone from accessing your account unless they also have access to your phone, making it much more secure.

Google provides a detailed guide to its two-step verification process that you can read here.

Be Careful with Email

Emails are another area where you need to be cautious. Attachments in emails are a common way of transmitting viruses, and phishing emails can allow criminals to capture your banking details and steal other personal information.

Make sure you have a powerful anti-spam feature in place, and don't even open spam unless you think it's from someone you know and has been mistakenly sent to your spam folder.

Never download attachments unless you are absolutely sure the email is from someone you trust. Anti-virus software can often scan attachments for viruses in case someone you trust has mistakenly sent you an infected file.

Phishing emails are fake emails designed to seem real. The most common scam is sending you an email claiming to be from your bank asking you to visit the website and enter your details.

When you click on the link, you're sent to a fake website, which might look exactly like your bank's site. You are then asked to log in with your username and password, and this is where the criminals steal your password and other secure details.

Real banks never send emails asking for your password information, so be very careful when you receive such an email. Always visit your bank's website from a new tab and type your address instead of clicking a link in an email.

Conclusion

Using the best antivirus like total security software is the simple solution to stay safe from all the threats, viruses, and malware which we can keep away from our devices and keep our data safe and secure.

7 Ways a Virus Can Attack Your Device | Total Security

These 'threats' respond to the name of Trojans, worms, computer viruses or spyware, among other possibilities. Be very careful with them! They could ruin all your information in a matter of seconds. To help you avoid this, we go over the 7 most common ways malicious software can 'sneak' onto your computer or device.

Ignore the Fake Virus Warnings!

Those ads that appear in pop-up windows, when you are browsing, to affirm that your computer is infected and invite you to click on them to solve the problem. They usually arise when we install or update a third program.

Delete Suspicious Emails!

Do not trust, even if the email you received is from your best friend, your sister or your coworker. Your device can be infected just by downloading an attachment or opening a link that contains malicious code. Also be careful with advertising emails or strangers. Make a responsible use of your email and you will avoid risks.

Download the Apps from The Official Stores!

One of the most frequent mechanisms for infecting mobile devices is by camouflaging viruses under the guise of programs that pretend to be games or applications. That is why it is always recommended to install apps from the official stores: Google Play, App Store, Windows Store, etc.

An App to View an Attached File?

Do not install it. Through email, social networks or instant messaging, sometimes we get files that we can only see if we install the suggested app. Careful! The virus is hidden in the 'kind' video player or image viewer that we just downloaded and installed to correctly view the file.

Be Careful with Hard Drives, USB Sticks and Removable Accessories!

Any hard drive or USB memory connected to our computer can contain different types of viruses. There are, in addition, other ways to infect our tablet or smartphone, such as, for example, the memory card (microSD) when we 'plug in' the mobile phone to the computer. The phone's own memory and the microSD card work as removable drives on the computer and, if it contains some kind of virus, it could easily be transferred to our phone.

Not All Web Pages Are 'Good'!

Behind some innocent-looking URLs, malicious web pages can be hidden. When we visit unknown links, we run the risk of ending up on a website that could access your computer or device and obtain all kinds of information about your system. Use link analysis software!

Piracy Can Come As A 'Surprise'!

Software linked to applications such as Bit Torrent for the illegal sharing of music, movies or software is another great risk to your computer or device. Sometimes these files and programs can contain viruses.

Conclusion

Your device can be infected with all these things and to keep it safe we should be using the best antivirus software like total security for keeping us safe and secure with all the threats, which can capture our data and use it for some wrong purpose.

Do You Know How Much Firewall Important to Your Organisation | Free Antivirus

The importance of information for the achievement of objectives in organizations has meant that it is considered in many cases as the most important asset. Due to the value attributed to it, it is subject to various threats such as theft, counterfeiting, fraud, disclosure, and destruction, among many others.

The risks to which such information is exposed lead to the need to develop trustworthy environments, but achieving this is a complex and multifactorial problem. For this reason, we have developed security approaches such as defense in depth (defense in depth), which aims to protect the information through the application of controls in different layers.

One of these layers is the perimeter, the logical boundary that divides the corporate network from other networks, including the Internet. In the so-called perimeter security, the firewall continues to be in force as a protection mechanism for networks and has been an essential element since its appearance 25 years ago.

Why Do Companies Need a Firewall?

Let's review first, what does this term refer to? It is a software or hardware tool whose purpose is to filter the connections that enter the internal network of the organization, as well as the network connections that go to the outside of the organization. It is implemented as a logical access control mechanism.

In this way, it prevents Internet users who have not been authorized to enter the company network from having access to it or from members of the organization accessing external services for which they have not been authorized.

So where does the importance of this lie? The firewall operates as a filter that examines all packets going to the corporate network and compares the information in the header with previously established rules. If the IP address and port are valid according to the rules, the packet is delivered, otherwise, it is discarded. The same operation is performed with the packages that are sent from the interior to the Internet.

Therefore, by discarding packets that are not allowed and consequently avoiding connections that are not valid according to the rules, the firewall can prevent the spread of malicious code through the network, unauthorized access, or possible intrusions of third parties to the corporate network.

However, it will not be able to protect against threats such as phishing or scam, since for the vast majority of organizations email is essential in their operations, so it is not blocked. Nor can it protect against malware infection, whether it arrives as an attachment or through removable media.

Now, how are the filtering rules defined? Basically, connections are allowed or denied based on criteria and rules that are defined. If a restrictive approach is applied, all connections are blocked except those that are explicitly allowed. On the other hand, if you use a permissive approach, all connections are accepted except those that are explicitly restricted.

The firewall configuration depends largely on the approach used, as well as the services that are offered, the services required by the members of the organization to carry out their tasks, and the assets that are intended to be protected.

Understanding the Importance of The Firewall

The firewall continues to be a highly used security mechanism in companies. According to the study, 76.6% of the executives surveyed in 14 countries in the region affirmed having a solution of this type, which places it in second place if we talk about the most used security controls, after antivirus.

The above, due to the benefits it provides in terms of protection, mainly by filtering external connections that some types of malicious software such as worms, viruses, or botnets usually make. Also, avoid the connections of possible intruders in the network or as a security measure to control connections to the outside.

Its Evolution in These 25 Years

Since its appearance, the firewall has evolved offering different protection features:

The first type developed was called for packet filtering (packet filter), and operates basically as described above: all packets arriving at the network and inspected according to the filtering rules, packets are accepted or discarded. To make the decision, it is verified if the basic information of the packet such as the source and destination address, the protocol, or the port, complies with the established rules or policies.

The second feature developed firewalls are known as stateful inspection (stateful inspection). Unlike the first type, the packets and the status of the connections that pass through them are tracked. In this case, only packets that match an active connection that has been recognized as legitimate are allowed to pass; all other packets are rejected.

The third type is known as filtering application (application filtering) and its main feature is that it detects whether the desired connection is not trying to avoid through an IP address and a valid port, according to the set rules. In other words, it is capable of controlling specific applications, since, in addition to checking the packet header, it also checks its content.

In recent years, people began to talk about new generation firewalls (NGFW), which must have additional functionalities to those described above. Although the new features should have not yet been fully defined, it is expected to combine the capabilities of Intrusion Prevention Systems (IPS), as well as their integration with other technologies, as well as broad and deep packet inspection. In the different layers of the OSI model.

A Single Control Is Not Enough

Despite the benefits that we have reviewed, firewalls are a solution applied only to one of the layers described in the in-depth security approach, so they must currently be complemented with other security controls regarding perimeter security, including Intrusion Detection Systems (IDS) or IPS.

In the same way, the other levels considered in layered security must be included, which can lead to the application of other controls necessary for companies such as free antivirus, antispam, practices such as data backup and encryption, double authentication solutions, even security solutions for mobile devices when they are used to access the corporate network.

We continue to see the evolution of this security mechanism, which remains in force as one of the fundamental elements for security management, and which currently should not be lacking when the purpose is to protect assets and mainly information in organizations.

Surf Anonymously & Safely: With These 6 Tips You Will Succeed

Our lives are increasingly taking place online. We access our employer's server via a VPN, transfers are only carried out online and appointments are saved in a calendar in the cloud. As many advantages as digitization bring - it also harbors dangers.

Because of what we like to forget in everyday life: When surfing, we are by no means safe or anonymous. An incredible number of companies are collecting as much data as they can possibly collect. Authorities follow our online activities.

If you want to escape this, you can use a few tips and tricks to regain a little more anonymity and security.

 

1. Observe Data Protection for Video Conferences

In the age of home offices, video conferences have become more and more popular and are now almost part of everyday life. It is all the more important that you deal intensively with the subject of data protection. Because in the worst case, the wrong settings could endanger the privacy of all participants.

Many companies use Zoom, a video conferencing service. It came under fire last year for allegedly lacking security. With a few settings, however, it is possible for you as the host to ensure sufficient security.

You must protect your conference with a password. Without this password, nobody can join the meeting - this protects against uninvited guests. Send the password directly to all participants with the announcement of the video conference.

You can also use the settings to protect the privacy of all participants. Turn off file transfer if not needed. You should also deactivate the “Screen sharing” function - the “Mute participant when joining” function, on the other hand, should be activated to avoid embarrassing situations.

If everyone has joined the conference, you can lock the meeting - then nobody can join. Alternatively, you can set up a waiting room and manually allow each participant.

 

2. Always Stay up To Date

You probably use well over 20 different programs in your private and professional everyday life. Be it your online calendar, a password manager, or a video conferencing service like Zoom. It always applies that you should always carry out all updates.

Updates are available from time to time for most programs. These can contain new or revised functions, for example. Much more important, however: They are there to close security gaps and remove bugs.

Security issues can arise in even the best programs. This is why you must install updates as they become available.

Not all services will automatically inform you of this. So check manually regularly whether new updates can be carried out. In doing so, you actively contribute to increasing your security.

 

3. Use Strong Passwords

Most services and tools these days can only be used with one user account. And that also means that you need a password. So well over 20 passwords come together.

Many users, therefore, use the same passwords over and over again or even a universal password for all services. This is absolutely dangerous because if this one password is cracked, criminals have access to different accounts of yours - in the worst case to all of them. There you can collect sensitive data and cause great damage with it.

This is why you must use a unique password for each website and program. Even if it is then cracked by hackers, the damage is unlikely to be that great.

Again, you can prevent this by using not only unique but also secure passwords. Many users use very insecure passwords like “12345” or “Password”. Criminals guess such passwords in seconds - they don't even need their professional tools that can crack passwords.

Strong passwords have several properties. They should be at least 10 characters long, preferably 12. You should use different characters (lowercase and uppercase letters, numbers, and special characters) and arrange them in random order.

Also, make sure to change the preset passwords immediately and not use your new passwords more than once. If you suspect that your password has been stolen, you should change it immediately.

Try to remember your passwords with a donkey bridge. You shouldn't write them down anywhere - not on sticky notes on your screen, or in a Word document.

If you have trouble memorizing a lot of complicated passwords, consider using a password manager. You enter all passwords in the secured database. To then access the passwords, you must enter a master password. This should of course be very secure and contain as many characters as possible.

Many password managers also offer you 2-factor authentication. Then the master password alone is not enough - you will then be sent a code to your smartphone, for example, which you must also enter.

 

4. Configure Your Browser Correctly

Aside from hackers, your browser settings can also threaten your privacy. A well-known example is cookies. They should actually make surfing easier for you - but nowadays they are mainly used for (cross-platform) tracking.

If you completely deactivate cookies, this will severely limit your use. For example, you can then no longer use the log-in function or the shopping cart. However, you can block third-party cookies and at least curb tracking. With a private window, you also protect yourself against browser fingerprinting.

A fundamental problem, however, is that many browsers also collect data from you themselves. The best example is Google Chrome - Google is known for collecting data like crazy.

Therefore you better use Firefox or the Brave Browser. The latter is an open-source browser with which you can easily delete recorded data. Comprehensive protective measures such as ad-blocking and anti-browser fingerprinting are set by default.

 

5. Optimize Google

When it comes to search engines, Google is way ahead of the competition. You can't get past Google. Read the data protection regulations and deactivate all tracking and tracing options if possible.

Important to know: There are also alternatives. Because there are now many search engines that have made it their business to combine the best search experience with the preservation of privacy.

DuckDuckGo now has over ten million searches a day. The search engine does not save your IP address, does not use tracking cookies, and uses encryption with HTTPS. There is also a hidden service and you can even access DuckDuckGo over the Tor network.

Startpage is also a safe alternative to Google. The self-proclaimed “most discreet search engine in the world” does not store any IP addresses, does not use tracking cookies, and even has an EU data protection certificate.

 

6. Surf with Tor or a VPN

You can ensure even more privacy and security with a VPN. This allows you to surf with a different IP address and encrypt all of your communication. Many Internet service providers record the activities of their customers and sell them for advertising purposes. In some cases, they will also throttle your connection.

Alternatively, you can use the Tor network. It consists of several layers and also encrypts your communication. I recommend a VPN because it's faster and easier than the Tor network.

 

Conclusion: More Anonymity and Security Are Possible

If you just start surfing these days, you risk your privacy. Whether hackers, internet providers, or your own browser - many offices are just waiting to collect your data. They are sold, collected for advertising, or recorded for other purposes.

Realize that you can protect yourself from all of this. And that is neither expensive nor particularly time-consuming.

To keep yourself safe you should use the best total security software.

Understand What Makes Hackers Tick and Protect Yourself Against Them

The Franzis textbooks of The hacking series explain comprehensively and also for users without prior knowledge understandable how hackers work and which programs and precautionary measures work effectively against cyber attacks.

Only recently infected that "WannaCry" malicious program Windows computers all over the world, causing chaos and great damage. After infesting a computer, the blackmail trojan encrypts valuable files on the target computer and asks users to pay ransom money in order to decrypt the data. Another malware attack is already running with “NotPetya”, which works on a very similar principle and also uses the “EternalBlue” hacking tool developed by the US secret service NSA.

In addition to large companies such as Deutsche Bahn, private individuals and their personal files such as documents and photos were also affected by “WannaCry”. While “WannaCry” was still primarily targeting older Windows versions, “NotPetya” also infiltrates newer systems and spreads to other computers via the company network.

Be it due to a poorly configured network or a wrong or missing update: It is often easy for hackers to gain access to company and private computers. To protect yourself against these attacks, you first have to get an overview of the various methods used by hackers. The Franzis textbooks of the Hacking series explain comprehensively and also for users without prior knowledge understandable how hackers work and which programs and precautionary measures work effectively against cyber attacks.

Secure Home and Company Networks with The Right Tools

One of the main distribution channels for malware, which was also used by the WannyCry and NotPetya attackers, is vulnerabilities in private and company networks. The fifth edition of the bestseller "Network Hacking" explains professional attack and defense techniques against hackers and data thieves and shows how home and company networks can be effectively secured. From the keylogger to the rootkit, various attack tools and the best countermeasures against them are explained, but the most important findings from the NSA affair can also be found in the almost 700-page book.

Repel Hackers on The Web

To know how to protect yourself against hacking attacks on the Internet, you need to understand how hackers think. The book "Hacking on the Web" provides web developers with the necessary knowledge on around 500 pages so that their applications do not become a gateway for attackers. Using various scenarios, author Tim Philip Schäfers explains common attack vectors such as cross-site scripting and SQL injection and then shows which tools developers use to protect their web applications against these attacks. Code examples are used to explain how to effectively analyze program code for weaknesses in order to close gaps as early as the implementation phase.

Neutralize Harmful Emails

E-mails are an integral part of our everyday life. In the flood of electronic messages, we usually open them without really thinking about it - and thus open the door to our computers for hackers. Because despite the spam filter, dangerous e-mails that contain Trojans or viruses or try to get our data with bait offers or phishing often find their way into our mailboxes. In addition to technical background knowledge, the book “E-Mail Hacking” provides valuable tips on how to identify and successfully defend against such attempted attacks. This book is a helpful reference work for more email security even for users without prior technical knowledge.

Your Own Hacking Laboratory

If you have always wanted to try out how a hacker works, the “Hacking Handbook” is exactly the right thing for you. With the help of free programs, you can easily and legally set up your own hacking laboratory, with which you can learn step by step how to carry out penetration tests on your own system. Be it spying on-network data or cracking passwords: Once you know how the hackers' methods work, you can better protect yourself against them and even forestall them. Try the best total security software to keep yourself ahead of hackers' attacks.

5 Measures for Online Shops to Protect Against Cyber Attacks | Antivirus

Measures to Protect Cyber Attacks

Data is the heart and engine of every webshop - cyber criminals know this and attack precisely there.

Regardless of whether customer payment data or trade secrets: data is the engine of every company. Cybercriminals know this and take advantage of this company's dependency on sensitive data: The number of online shops attacked by hackers doubles every year.

Cybercriminals can exploit security holes in the website of an online shop to smuggle various forms of malware into the system. Once in the system, the malware can be used for different purposes. Companies are most often affected by blackmail trojans, so-called ransomware, and espionage ware. Automated ransomware in particular has already made negative headlines this year. In May 2017, the WannaCry blackmail trojan spread rapidly around the world in over 150 countries and caused over 200,000 victims. Spyware attacks are less loud but no less deadly for online shops. To be able to act successfully, spyware lies well camouflaged in the attacked company's shop system and can access customer data there.

Backups: Define Important Data and Save It Separately

Companies should know which of their data is particularly worth protecting. Sensitive data should be named and localized - mobile work devices also make it difficult for decision-makers to maintain an overview of existing data.

An external backup is a solid basis for companies to create a minimum of basic backup. External data backup is the ideal solution here, as there is no connection to a network and hackers cannot access the data. Manual external backup requires discipline as backups must take place regularly. In the event of an attack, companies can quickly resume operations with an up-to-date backup. The backup also means that in the event of a ransomware attack, the cybercriminals do not have to respond to their demands.

Passwords: What Should the Password Structure of The Site Be Like?

Few decision-makers are aware of the benefits their passwords have for cybercriminals. Not only e-mail addresses can be profitably sold on the Darknet and - if the successful hack becomes known - reputational damage with financial consequences. Hackers can use the stolen password to access the company's system to access customer payment data. The resulting compensation payments or lawsuits from customers can be very costly.

Nevertheless, passwords in the company are often chosen with the focus on being able to remember them as easily as possible. The same password is often chosen for each area so that cybercriminals gain access to sensitive areas and critical company assets in the event of an attack.

Patch Management: CMS and Shop Software Updates Are Labor-Intensive, but Necessary

Updates are not only necessary for the functionality of the operating system or software. With each update, manufacturers fix known security gaps in their software and their plugins. The attack form of the "zero-day exploit" is based on the real-time exploitation of security gaps in software or plugins that have only recently become known. A prerequisite for exploiting this security gap is that it has not already been closed by updates. The WannaCry ransomware, which is responsible for the largest and most momentous global wave of cyberattacks to date, was only able to cause so much damage because companies have not closed known vulnerabilities with an update for several months. End devices can be configured in such a way that they automatically carry out updates.

Web Server: Write Permissions as An Invitation for Malware

The ideal way to prevent malware from being executed is to whitelist applications. So only certain applications can run files in the system. Since such a whitelisting is very time-consuming, write permissions can also be restricted initially. Here only certain directories are authorized to execute files. Thanks to this precautionary measure, no (accidentally downloaded) ransomware can, for example, be executed from temporary storage directories, as long as only other, specified directories have to write access.

Virus Scanners & Firewalls: Keep Parasites Away with The Right Antivirus Software

Even if it is part of the standard repertoire of every operating system: A good antivirus program can also protect against ransomware such as WannaCry. Many of the common antivirus programs can detect not only viruses but also malware.

Spyware and any other malware can nestle in the internal system via the web server and tap into business secrets there. Stolen data can be sold or used to build inexpensive product copies. Particularly dangerous: With the data protection regulation coming into force.
