Shortly about backdoors
Is Backdoor:MSIL/Remcos!mclg dangerous?
As I have actually mentioned before, non-harmful malware does not exist. And Backdoor:MSIL/Remcos!mclg is not an exclusion. This backdoor does not deal a many harm just after it releases. Nevertheless, it will likely be a very bad surprise when a random forum or page in the Internet will not let you in, because your IP-address is disallowed after the DDoS attack. But even if it is not crucial for you – is it nice at all to realise that someone can easily access your computer, check out your discussions, open your documents, as well as spectate what you do?
The spyware that is frequently present as a supplement to the Backdoor:MSIL/Remcos!mclg virus will likely be just an additional argument to remove it as fast as you can. Nowadays, when users’ information is valued remarkably high, it is too goofy to grant the criminals such a chance. Even worse if the spyware will in some way manage to take your banking information. Seeing zeros on your savings account is the worst problem, in my judgement.
How did I get this virus?
It is difficult to trace the origins of malware on your computer. Nowadays, things are mixed, and spreading methods utilized by adware 5 years ago may be used by spyware these days. However, if we abstract from the exact distribution way and will think about why it works, the explanation will be very basic – low level of cybersecurity understanding. People click on advertisements on strange websites, click the pop-ups they get in their browsers, call the “Microsoft tech support” believing that the weird banner that states about malware is true. It is important to know what is legit – to prevent misconceptions when trying to find out a virus.

Microsoft Tech Support Scam
Nowadays, there are two of the most widespread ways of malware distribution – bait emails and also injection into a hacked program. While the first one is not so easy to stay away from – you should know a lot to recognize a fake – the second one is simple to address: just don’t utilize cracked apps. Torrent-trackers and other providers of “totally free” applications (which are, exactly, paid, but with a disabled license checking) are really a giveaway point of malware. And Backdoor:MSIL/Remcos!mclg is just one of them.
