Shortly about backdoors

Backdoors are viruses that can acquire both separated and incorporated shapes. Once you may discover that a legit program from a famous developer has a capability that allows someone to connect to your system. Will it be someone from the developers or a 3rd party – no one knows. But the scandal when this aspect is spotted in a legitimate program is almost impossible to miss. There is also gossip that there is a hardware-based backdoor in Intel CPUs1.

Is Backdoor:MSIL/Quasar!atmn dangerous?

As I have actually stated , non-harmful malware does not exist. And Backdoor:MSIL/Quasar!atmn is not an exception. This backdoor does not deal a lot of harm exactly after it launches. Nevertheless, it will be a pretty bad surprise when a random discussion forum or site in the Internet will not let you in, since your IP-address is disallowed after the DDoS attack. But even if it is not important for you – is it positive at all to understand that someone can simply access your PC, read your conversations, open your documents, and spectate what you do?

The spyware that is frequently present as a supplement to the Backdoor:MSIL/Quasar!atmn malware will be just an additional reason to remove it as fast as you can. Nowadays, when users’ data is valued remarkably high, it is too goofy to grant the crooks such a chance. Even worse if the spyware will in some way manage to grab your financial info. Seeing zeros on your savings account is the worst problem, in my opinion.
