The Trojan:MSIL/Mamut.AFYN!MTB alert, is a sign that your PC has a problem. Allowing it to run may lead to some really bad consequences. Mamut detection stands for an array of remote access trojans, particularly zgRAT malware family.
Backdoors like Mamut are versatile threats that are able to act as autonomous malware, and be used in multi-stage attacks. Their key target is creating a remote access point to the infected system, that operates without the victim’s knowledge. To prevent any interruptions, this malware type tries to stay as low as possible.
Trojan:MSIL/Mamut.AFYN!MTB Detection Overview
The Trojan:MSIL/Mamut.AFYN!MTB detection you can see in the lower right side is displayed to you by Microsoft Defender. That anti-malware application is pretty good at scanning, however, prone to be basically unreliable. It is vulnerable to malware attacks, it has a glitchy interface and bugged malware clearing features. For this reason, the pop-up which states concerning the Mamut is rather just a notification that Defender has identified it. To remove it, you will likely need to make use of another anti-malware program.

Shortly about backdoors
Backdoors are viruses that can acquire both separated and built-in shapes. Once you can discover that an official program from a widely known company has a capability that enables somebody to connect to your system. Will it be someone from the developers or a 3rd party – nobody knows. However, the scandal when this detail is uncovered in a legit program is almost impossible to miss. There is also chatter that there is a hardware-based backdoor in Intel CPUs1.
Is Trojan:MSIL/Mamut.AFYN!MTB dangerous?
As I have actually specified previously, non-harmful malware does not exist. And Trojan:MSIL/Mamut.AFYN!MTB is not an exclusion. This backdoor does not deal a lot of harm just after it introduces. Nevertheless, it will be a pretty unpleasant surprise when a random discussion forum or website in the Web will not let you in, since your IP-address is banned after the DDoS attack. However, even if it is not critical for you – is it enjoyable in any way to realize that someone can simply access your PC, check out your discussions, open your documents, and spectate what you do?
The spyware that is usually present as a supplement to the Trojan:MSIL/Mamut.AFYN!MTB malware will be just an additional argument to remove it as fast as you can. Nowadays, when users’ data is valued remarkably high, it is too silly to provide the criminals such a possibility. Even worse if the spyware will in some way handle to take your banking information. Seeing 0 on your bank account is the worst problem, in my judgement.
How did I get this virus?
It is not easy to trace the sources of malware on your computer. Nowadays, things are mixed, and distribution ways utilized by adware 5 years ago may be utilized by spyware nowadays. But if we abstract from the exact distribution method and will think about why it works, the reply will be pretty basic – low level of cybersecurity understanding. People press on ads on weird websites, click the pop-ups they receive in their browsers, call the “Microsoft tech support” thinking that the scary banner that states about malware is true. It is important to know what is legit – to avoid misunderstandings when trying to find out a virus.

The example of Microsoft Tech support scam banner
Nowadays, there are two of the most widespread methods of malware spreading – bait emails and injection into a hacked program. While the first one is not so easy to avoid – you must know a lot to understand a counterfeit – the 2nd one is simple to handle: just don’t utilize hacked programs. Torrent-trackers and other sources of “free” applications (which are, exactly, paid, but with a disabled license checking) are really a giveaway point of malware. And Trojan:MSIL/Mamut.AFYN!MTB is just amongst them.
