Any type of malware exists with the only target – gain money on you1. And the programmers of these things are not thinking of ethicality – they utilize all available tactics.

What does the notification with Backdoor:MSIL/DCRat!MSR detection mean?

The Backdoor:MSIL/DCRat!MSR detection you can see in the lower right side is displayed to you by Microsoft Defender.

Therefore, the pop-up which says about the DCRat is rather just an alert that Defender has actually identified it. To remove it, you will likely need to make use of another anti-malware program.

The exact Backdoor:MSIL/DCRat!MSR virus is a really unpleasant thing. This malware is designed to be a stealthy intruder, which serves as a remote-access tool. When you provide someone else remote access willingly, it is okay, but DCRat will not ask you if you want to give it. After connecting to your PC, criminals are able to do whatever they want – getting your files, examining your messages, picking up personal information, and so on. Backdoors frequently bring a supplementary stealer – the virus that is created to pick up all possible information about you. However, much more widespread use of the backdoors is setting up the botnet. Then, the network of infected systems can be put to use to perform DDoS attacks or to inflate the poll results on various web pages.

Once you may find that a legit program from a famous company has a functionality that allows somebody to connect to your computer. Will it be somebody from the creators or a 3rd party – no one knows.

Is Backdoor:MSIL/DCRat!MSR dangerous?

However, if we abstract from the exact distribution way and will think about why it has success, the explanation will be quite simple – low level of cybersecurity awareness. Individuals click on ads on strange sites, click the pop-ups they get in their web browsers, call the “Microsoft tech support” believing that the strange banner that says about malware is true. It is essential to know what is legitimate – to prevent misunderstandings when trying to find out a virus.
