Any kind of malware exists with the only target – gain money on you1. And the programmers of these things are not thinking of morality – they utilize all available methods. Taking your private data, getting the payments for the banners you watch for them, exploiting your CPU and GPU 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.Win32.Remcos detection mean?

The Trojan:Win32/Remcos detection you can see in the lower right side is demonstrated to you by Microsoft Defender. That anti-malware software is quite OK at scanning, however, prone to be generally unreliable. It is prone to malware invasions, it has a glitchy interface and problematic malware clearing capabilities. Therefore, the pop-up which says about the Remcos is simply a notification that Defender has found it. To remove it, you will likely need to use a separate anti-malware program.

Microsoft Defender: “Trojan:Win32/Remcos”

The exact Backdoor.Win32.Remcos virus is a very nasty thing. This malware is designed to be a sneaky burglar, which functions as a remote-access tool. When you grant somebody remote access willingly, it is OK, but Remcos will not ask you if you would like to give it. After connecting to your system, crooks are able to do whatever they want – snatching your files, browsing your messages, gathering personal data, and so on. Backdoors often bring a supplementary stealer – the virus that is developed to gather all available data about you. Nonetheless, far more widespread use of the backdoors is creating the botnet. After that, the network of infected PCs may be used to conduct DDoS attacks or to inflate the vote results on various web pages.

Shortly about backdoors

Backdoors are viruses that can obtain both separated and incorporated shapes. Once you may find that an official program from a well-known company has a functionality that makes it possible for somebody to connect to your system. Will it be somebody from the creators or a 3rd party – no one knows. But the scandal when this thing is identified in an official program is nearly impossible to miss. There is additionally chatter that there is a hardware-based backdoor in Intel CPUs2.

Is Backdoor.Win32.Remcos dangerous?

As I have mentioned previously, non-harmful malware does not exist. And Backdoor.Win32.Remcos is not an exclusion. This backdoor does not deal a many harm just after it releases. Nevertheless, it will likely be a really bad surprise when an occasional forum or website in the Web will not let you in, due to the fact that your IP-address is disallowed after the DDoS attack. But even if it is not critical for you – is it pleasant in any way to know that someone can easily access your PC, read your discussions, open your documents, as well as spectate what you do?

The spyware that is often present as a supplement to the Backdoor.Win32.Remcos virus will be just an additional argument to remove it as fast as you can. Nowadays, when users’ data is priced very high, it is too goofy to provide the criminals such an opportunity. Even worse if the spyware will somehow manage to steal your banking information. Seeing zeros on your savings account is the worst headache, in my opinion.

How did I get this virus?

It is difficult to trace the origins of malware on your PC. Nowadays, things are mixed, and distribution ways utilized by adware 5 years ago can be used by spyware nowadays. But if we abstract from the exact spreading tactic and will think of why it works, the answer will be quite basic – low level of cybersecurity knowledge. People press on promotions on strange websites, click the pop-ups they receive in their web browsers, call the “Microsoft tech support” believing that the odd banner that says about malware is true. It is very important to know what is legitimate – to stay away from misconceptions when attempting to determine a virus.

Nowadays, there are two of the most widespread tactics of malware distribution – lure e-mails 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 counterfeit – the second one is easy to solve: just don’t use hacked programs. Torrent-trackers and various other sources of “free” applications (which are, exactly, paid, but with a disabled license checking) are just a giveaway place of malware. And Trojan:Win32/Remcos is just within them.
