Any malware exists with the only target – gain money on you1. And the programmers of these things are not thinking about morality – they utilize all available methods. Grabbing your private data, getting the payments for the banners you watch for them, utilizing your hardware to mine cryptocurrencies – that is not the complete list of what they do. Do you like to be a riding horse? That is a rhetorical question.

What does the notification with Backdoor:MSIL/Remcos!mclg detection mean?

The Backdoor:MSIL/Remcos!mclg detection you can see in the lower right side is demonstrated to you by Microsoft Defender. That anti-malware software is good at scanning, but prone to be mainly unstable. It is unprotected to malware attacks, it has a glitchy interface and bugged malware removal capabilities. Therefore, the pop-up which states about the Remcos is simply an alert that Defender has identified it. To remove it, you will likely need to make use of a separate anti-malware program.

Microsoft Defender: “Backdoor:MSIL/Remcos!mclg”

The exact Backdoor:MSIL/Remcos!mclg virus is a very undesirable thing. This malware is created to be a stealthy trespasser, which acts as a remote-access tool. When you give someone else remote access willingly, it is alright, but Remcos will not ask you if you would like to give it. After connecting to your system, crooks are free to do whatever they want – grabbing your files, examining your messages, collecting personal information, et cetera. Backdoors commonly carry an additional stealer – the virus that is made to gather all available data about you. Nevertheless, far more prevalent use of the backdoors is forming the botnet. Then, the network of corrupted systems may be put to use to perform DDoS attacks or to inflate the survey results on various web pages.

Shortly about backdoors

Backdoors are viruses that can acquire both separated and integrated shapes. One time you can uncover that an official program from a reputable developer has a functionality that makes it possible for someone to connect to your system. Will it be someone from the creators or a third party – no one knows. But the scandal when this feature is discovered in an official program is probably impossible to miss. There is additionally gossip that there is a hardware-based backdoor in Intel CPUs2.

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.

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.

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.
