Image
People often think of computer security as both technical and complex. And it can be if you get to the point. Here are some basic and important things to do to make it safer online. Use automatic updates All the software we use every day is full of security issues. Windows, Internet Explorer, Mozilla Firefox, Google Chrome, Adobe Flash plugin, Adobe PDF Reader, Microsoft Office, etc. All security issues continue to be discovered. Many operating systems and programs these days offer automatic updates to address these security vulnerabilities. You no longer need to click a button or download a file to update your software.

If you previously turned off automatic updates, use the softwa...

To Protect Yourself From Unpleasant Situations | Total Security

Image
To protect yourself from unpleasant situations, you must observe the utmost care and safety rules on the Internet. Remember: you cannot be confident in a person you do not know personally, so distrust in absentia to any new acquaintance is a completely justified measure. Do not provide any personal information about yourself, especially about accounts, contacts and personal data. The less an attacker knows about you, the less he can do. Do not accept any files from unverified people, much less install them. For the sent "funny chip" or "toy" may turn out to be a Trojan or a virus that will cause a lot of trouble.  Internet Behavior Do not take all the words of Internet interlocutors at face value. Messages like “urgently put money into my account, then I'll return it” or “call me on such and such a number” in 100% of cases will turn out to be a divorce. Also, do not follow the links, even if it is supposedly a page with someone's photos. At best, advertising...

How to Remove Viruses and Trojans | Antivirus Software

Image
The process of removing viruses from your computer is thorny. Malicious programs have learned well how to protect themselves from antivirus software. It happens that it is impossible to remove viruses at once. We have to run the anti-virus programs several times, with several anti-virus programs. The point is that each anti-virus program has its own anti-virus database. It is continuously replenished with fresh bodies of new viruses. Only fresh viruses are dangerous for infection. And it's not a fact that such viruses are included in the database of one antivirus. The likelihood of detecting a new virus increases with the number of antivirus programs in use. Conclusion: the more antivirus scanned your computer, the higher the chances of removing the virus. Many viruses cannot be cured on an infected computer. Moreover, often you cannot install an antivirus on an infected computer. Viruses have learned to block the installation of antiviruses. A radical virus removal begins with re...

Who is Behind the Sites With Viruses? Free Antivirus

Image
In most cases, they are hooligans who consider themselves "tough hackers". But there are also idealists who want to point out to software vendors the weaknesses in the security system of their software. Some call themselves "extremists" who simply do not have enough adrenaline. There are also quite a few hackers, driven exclusively by "illegal" motives, seeking to earn as much as possible by deceiving ordinary users and software companies. But in any case, working with viruses stimulates the study of technology. Who are Hackers? Highly qualified technicians who are able to leverage undocumented digital hardware and software capabilities. The word "hacker" is not synonymous with the word "cybercriminal," and "hacking" is not a crime in itself. The hacker is not taught anywhere. Most hackers combine "standard" technical training with active self-education. For example, programming languages, the principles of hardware,...

The Difference Between a Virus, a Worm, and a Trojan Horse

Image
Malware The most common mistake when talking about a computer virus is to talk about viruses to refer to a worm or a Trojan horse. The terms Trojan horse, worm, and virus are generally used interchangeably, but they are not the same thing. Viruses, worms, and Trojans are malicious programs, all three of which can harm your computer, but in different ways. Knowing these differences can help you better protect your computer from their often destructive effects. Knowing the Differences Can Help You Better Protect Your Computer A computer virus attaches itself to a program or file from which it can spread from one computer to another, sowing infections wherever it goes. Much like human viruses, computer viruses can be more or less serious: some viruses only have mild disturbing effects, while others can damage your hardware, software, or files. Almost all viruses are included in an executable file, which means that the virus may be present on your computer, but in reality, it cannot infect...

Worms, viruses, and Trojan horses are various types of malware that often cause damage to your computer. Knowing the difference between them, you can reliably protect your computer from their malicious actions. What is a Virus? The virus attaches itself to a file or program so that it can move from one PC to another, leaving infections wherever it goes.

Since the virus spreads as a result of human activity, users unknowingly continue to spread the computer virus by exchanging information, for example, as an attachment in an e-mail with an infected file. What is a worm? The worm is similar in structure to a viru...

Contact Tracing: Beware of Bluetooth Vulnerabilities

Image
With the trend of contact tracing applications, attacks exploiting Bluetooth vulnerabilities are likely to increase.  It is, therefore, necessary to ensure the security of such applications.  Security researchers are also advising all users to update their mobile devices to ensure they fix any past security vulnerabilities.
