The exact Backdoor:Win32/Mestys.A virus is a really nasty thing. This malware is developed to be a stealthy trespasser, which serves as a remote-access tool. When you willingly give someone else remote access, it is OK, but Mestys.A will not ask you if you wish to provide it. After connecting to your system, crooks are able to do whatever they want – grabbing your files, browsing your messages, gathering personal information, et cetera. Backdoors commonly carry an additional stealer – the virus that is created to collect all possible information about you. However, a lot more common use of the backdoors is creating the botnet.

Shortly about backdoors

Backdoors are viruses that may acquire both separated and built-in shapes. One time you may uncover that an official program from a widely known company has a functionality that makes it possible for somebody to connect to your system. Will it be someone from the creators or a 3rd party – nobody knows. However, the scandal when this feature is spotted in an official program is pretty much impossible to miss. There is additionally gossip that there is a hardware-based backdoor in Intel CPUs1.

Is Backdoor:Win32/Mestys.A dangerous?

As I have pointed out before, non-harmful malware does not exist. And Backdoor:Win32/Mestys.A is not an exception. This backdoor does not deal a lot of damage just after it launches. Nevertheless, it will likely be a really unpleasant surprise when a random discussion forum or page in the Internet will not let you in, since your IP-address is disallowed after the DDoS attack. But even if it is not vital for you – is it positive at all to realise that someone can simply access your computer, read your discussions, open your files, and spectate what you do?

The spyware that is frequently present as a supplement to the Backdoor:Win32/Mestys.A virus will likely be just one more reason to remove it as fast as you can. Nowadays, when users’ data is valued remarkably high, it is too illogical to give the criminals such a chance. Even worse if the spyware will somehow manage to steal your financial information. Seeing zeros on your financial account is the most awful nightmare, in my point of view.

How did I get this virus?

It is not easy to trace the sources of malware on your computer. Nowadays, things are mixed up, and spreading ways chosen by adware 5 years ago may be utilized by spyware these days. But if we abstract from the exact spreading way and will think about why it works, the explanation will be very uncomplicated – low level of cybersecurity understanding. People press on ads on strange sites, click the pop-ups they get in their browsers, call the “Microsoft tech support” assuming that the scary banner that states about malware is true. It is very important to recognize what is legit – to prevent misunderstandings when trying to find out a virus.

Nowadays, there are two of the most common methods of malware distribution – lure emails and injection into a hacked program. While the first one is not so easy to stay away from – you should know a lot to understand a counterfeit – the 2nd one is simple to address: just do not utilize cracked applications. Torrent-trackers and various other providers of “totally free” applications (which are, exactly, paid, but with a disabled license checking) are just a giveaway point of malware. And Backdoor:Win32/Mestys.A is just amongst them.

How to remove the Backdoor:Win32/Mestys.A from my PC?
