Any type of malware exists with the only target – generate profits on you1. And the developers of these things are not thinking about morality – they utilize all possible methods. Stealing your private data, receiving the payments for the banners you watch for them, exploiting your PC 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/Downloader.BK!MTB detection mean?

The Trojan:MSIL/Downloader.BK!MTB detection you can see in the lower right side is shown to you by Microsoft Defender. That anti-malware application is pretty good at scanning, however, prone to be mainly unstable. It is defenseless to malware invasions, it has a glitchy user interface and problematic malware removal features. For this reason, the pop-up which says concerning the Downloader is simply an alert that Defender has actually identified it. To remove it, you will likely need to use another anti-malware program.

The exact Trojan:MSIL/Downloader.BK!MTB infection is a really nasty thing. It digs into your Windows under the guise of something normal, or as a piece of the application you have got on a forum. Therefore, it makes everything to make your system weaker. At the end of this “party”, it downloads other malicious things – ones which are choosen by cybercriminals who manage this virus. Hence, it is impossible to predict the effects from Downloader actions. And the unpredictability is one of the baddest things when we are talking about malware. That’s why it is rather not to choose at all, and don’t let the malware to complete its task.

Is Trojan:MSIL/Downloader.BK!MTB dangerous?

As I have actually pointed out previously, non-harmful malware does not exist. And Trojan:MSIL/Downloader.BK!MTB is not an exception. This malware changes the system settings, modifies the Group Policies and Windows registry. All of these things are vital for proper system functioning, even when we are not talking about system security. Therefore, the virus which Downloader contains, or which it will download after some time, will try to get maximum profit from you. Cybercriminals can grab your personal data, and then sell it at the black market. Using adware and browser hijacker functionality, built in Trojan:MSIL/Downloader.BK!MTB virus, they can make money by showing you the advertisements. 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 not easy to line the origins of malware on your PC. Nowadays, things are mixed up, and distribution ways chosen by adware 5 years ago may be used by spyware these days. But if we abstract from the exact distribution way and will think about why it works, the explanation will be pretty simple – low level of cybersecurity understanding. People click on promotions on weird sites, click the pop-ups they receive in their browsers, call the “Microsoft tech support” assuming that the scary banner that says about malware is true. It is necessary to understand what is legitimate – to prevent misunderstandings when attempting to figure out a virus.

Nowadays, there are two of the most common ways of malware distribution – bait emails and injection into a hacked program. While the first one is not so easy to avoid – you should know a lot to understand a counterfeit – the 2nd one is easy to get rid of: just don’t use cracked apps. Torrent-trackers and various other providers of “totally free” applications (which are, exactly, paid, but with a disabled license checking) are just a giveaway point of malware. And Trojan:MSIL/Downloader.BK!MTB is simply within them.

How to remove the Trojan:MSIL/Downloader.BK!MTB from my PC?

Trojan:MSIL/Downloader.BK!MTB malware is extremely hard to eliminate manually. It puts its data in numerous places throughout the disk, and can get back itself from one of the parts.
