Any malware exists with the only target – generate profits on you1. And the programmers of these things are not thinking of morality – they use all possible ways. Grabbing your personal data, receiving the comission for the banners you watch for them, exploiting your hardware to mine cryptocurrencies – that is not the complete list of what they do. Do you like to be a riding steed? That is a rhetorical question.

What does the notification with Trojan:MSIL/r77Rootkit.A!MTB detection mean?

The Trojan:MSIL/r77Rootkit.A!MTB detection you can see in the lower right corner is demonstrated to you by Microsoft Defender. That anti-malware application is good at scanning, however, prone to be generally unreliable. It is defenseless to malware attacks, it has a glitchy user interface and bugged malware removal features. For this reason, the pop-up which states concerning the r77 is just a notification that Defender has actually spotted it. To remove it, you will likely need to make use of another anti-malware program.

The exact Trojan:MSIL/r77Rootkit.A!MTB virus is a very undesirable thing. It sits inside of your Windows under the guise of something normal, or as a piece of the application you downloaded at a forum. Then, it makes everything to make your system weaker. At the end of this “party”, it injects other viruses – ones which are choosen by cyber burglars who control this virus. Hence, it is likely impossible to predict the effects from r77 actions. And the unpredictability is one of the baddest things when it comes to malware. That’s why it is rather not to choose at all, and don’t give it even a single chance to complete its task.

Is Trojan:MSIL/r77Rootkit.A!MTB dangerous?

As I have pointed out previously, non-harmful malware does not exist. And Trojan:MSIL/r77Rootkit.A!MTB is not an exclusion. This virus alters the system settings, alters the Group Policies and Windows registry. All of these components are crucial for proper system functioning, even when we are not talking about Windows safety. Therefore, the malware which r77 carries, or which it will download after some time, will try to get maximum profit from you. Cyber burglars can steal your personal data, and then sell it on the Darknet. Using adware and browser hijacker functions, embedded in Trojan:MSIL/r77Rootkit.A!MTB malware, they can make profit by showing you the ads. Each view gives them a penny, but 100 views per day = $1. 1000 victims who watch 100 banners per day – $1000. Easy math, but sad conclusions. It is a bad choice to be a donkey for crooks.

How did I get this virus?

It is difficult to trace the origins of malware on your computer. Nowadays, things are mixed, and distribution ways chosen by adware 5 years ago may be utilized by spyware nowadays. But if we abstract from the exact spreading method and will think about why it has success, the explanation will be quite uncomplicated – low level of cybersecurity understanding. Individuals press on ads on strange sites, click the pop-ups they receive in their web browsers, call the “Microsoft tech support” thinking that the strange banner that states about malware is true. It is essential to understand what is legitimate – to avoid misconceptions when attempting to determine a virus.

Nowadays, there are two of the most common tactics of malware spreading – bait e-mails and injection into a hacked program. While the first one is not so easy to avoid – you need to know a lot to understand a fake – the second one is easy to solve: just do not utilize hacked applications. Torrent-trackers and various other sources of “totally free” applications (which are, exactly, paid, but with a disabled license checking) are just a giveaway point of malware. And Trojan:MSIL/r77Rootkit.A!MTB is just one of them.
