Any kind of malware exists with the only target – make money on you1. And the developers of these things are not thinking about morality – they use all possible tactics. Taking your personal data, getting the payments for the promotions 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 equine? That is a rhetorical question.
What does the notification with Trojan:PowerShell/Malagent!MSR detection mean?
The Trojan:PowerShell/Malagent!MSR detection you can see in the lower right corner is displayed to you by Microsoft Defender. That anti-malware software is good at scanning, but prone to be generally unreliable. It is unprotected to malware attacks, it has a glitchy user interface and problematic malware clearing features. Hence, the pop-up which states about the Malagent is just an alert that Defender has actually spotted it. To remove it, you will likely need to use another anti-malware program.
Microsoft Defender: “Trojan:PowerShell/Malagent!MSR”
The exact Trojan:PowerShell/Malagent!MSR virus is a very unpleasant thing. It digs inside of your system disguised as a part of something legitimate, or as a piece of the tool you downloaded from a forum. After that, it makes all possible steps to make your system weaker. At the end of this “party”, it downloads other viruses – ones which are wanted by crooks who manage this malware. Hence, it is almost impossible to predict the effects from Malagent actions. And the unpredictability is one of the most upleasant things when it comes to malware. That’s why it is rather not to choose at all, and don’t let the malware to complete its task.

Is Trojan:PowerShell/Malagent!MSR dangerous?
As I have actually specified , non-harmful malware does not exist. And Trojan:PowerShell/Malagent!MSR is not an exception. This malware changes the system configurations, edits the Group Policies and Windows registry. All of these components are vital for correct system operating, even when we are not talking about Windows security. Therefore, the malware which Malagent contains, or which it will inject after some time, will squeeze out maximum profit from you. Crooks can steal your personal data, and then push it at the black market. Using adware and browser hijacker functionality, built in Trojan:PowerShell/Malagent!MSR virus, they can make revenue 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 not easy to trace the sources of malware on your computer. Nowadays, things are mixed up, and distribution tactics used by adware 5 years ago may be used by spyware these days. However, if we abstract from the exact spreading way and will think of why it works, the explanation will be really simple – low level of cybersecurity awareness. People click on ads on odd websites, click the pop-ups they receive in their browsers, call the “Microsoft tech support” assuming that the odd banner that states about malware is true. It is important to recognize what is legit – to prevent misconceptions when trying to find out a virus.

Nowadays, there are two of the most extensive methods of malware spreading – lure emails and injection into a hacked program. While the first one is not so easy to avoid – you should know a lot to recognize a counterfeit – the second one is easy to address: just don’t utilize hacked apps. Torrent-trackers and various other sources of “totally free” applications (which are, actually, paid, but with a disabled license checking) are just a giveaway place of malware. And Trojan:PowerShell/Malagent!MSR is just amongst them.
