Any malware exists with the only target – make money on you1. And the developers of these things are not thinking about morality – they utilize all possible ways. Taking your personal data, receiving the payments for the ads you watch for them, exploiting your system components 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/Zapchast!MSR detection mean?

The Trojan:MSIL/Zapchast!MSR detection you can see in the lower right corner is displayed to you by Microsoft Defender. That anti-malware program is good at scanning, but prone to be basically unstable. It is defenseless to malware attacks, it has a glitchy interface and bugged malware removal features. Hence, the pop-up which states about the Zapchast is just a notification that Defender has actually identified it. To remove it, you will likely need to use another anti-malware program.

The exact Trojan:MSIL/Zapchast!MSR infection is a really undesirable thing. It is present inside of your computer disguised as a part of something normal, or as a part of the application you have got on a forum. Therefore, it makes all possible steps 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 almost impossible to predict the effects from Zapchast actions. And the unpredictability is one of the baddest things when it comes to malware. That’s why it is better not to choose at all, and don’t give it even a single chance to complete its task.

Is Trojan:MSIL/Zapchast!MSR dangerous?

As I have actually pointed out , non-harmful malware does not exist. And Trojan:MSIL/Zapchast!MSR is not an exception. This virus changes the system setups, modifies the Group Policies and registry. All of these things are crucial for proper system operating, even in case when we are not talking about PC security. Therefore, the virus which Zapchast carries, or which it will download later, will try to get maximum profit from you. Crooks can steal your personal data, and then sell it at the black market. Using adware and browser hijacker functions, embedded in Trojan:MSIL/Zapchast!MSR malware, they can make profit by showing you the banners. 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 line 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 tactic and will think of why it has success, the reply will be very uncomplicated – low level of cybersecurity knowledge. People click on promotions on strange websites, open the pop-ups they receive in their browsers, call the “Microsoft tech support” assuming that the odd banner that says about malware is true. It is very important to understand what is legitimate – to stay away from misunderstandings when trying to determine a virus.

Nowadays, there are two of the most common tactics of malware distribution – lure emails and injection into a hacked program. While the first one is not so easy to evade – you should know a lot to recognize a fake – the 2nd one is simple to get rid of: just do not utilize hacked programs. Torrent-trackers and other sources of “totally free” applications (which are, in fact, paid, but with a disabled license checking) are just a giveaway point of malware. And Trojan:MSIL/Zapchast!MSR is just among them.

How to remove the Trojan:MSIL/Zapchast!MSR from my PC?
