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.

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.

And Trojan:MSIL/r77Rootkit.A!MTB is just one of them.
