Any kind of malware exists with the only target – generate profits on you1. And the developers of these things are not thinking about morality – they use all possible tactics. Stealing your personal data, getting the comission for the ads you watch for them, exploiting your hardware to mine cryptocurrencies – that is not the full list of what they do. Do you like to be a riding steed? That is a rhetorical question.

What does the notification with Trojan:JS/KryptoStealer.GA!MSR detection mean?

The Trojan:JS/KryptoStealer.GA!MSR detection you can see in the lower right side is demonstrated to you by Microsoft Defender. That anti-malware application is pretty good at scanning, however, prone to be basically unreliable. It is unprotected to malware attacks, it has a glitchy interface and problematic malware clearing capabilities. Therefore, the pop-up which says about the Krypto Stealer is rather just a notification that Defender has recognized it. To remove it, you will likely need to use another anti-malware program.

The exact Trojan:JS/KryptoStealer.GA!MSR infection is a really nasty thing. It digs into your computer disguised as a part of something normal, or as a part of the program you have got on a forum.

Hence, it is likely impossible to predict the effects from Krypto Stealer actions. And the unpredictability is one of the most unwanted things when we are talking about malware.

Is Trojan:JS/KryptoStealer.GA!MSR dangerous?

As I have mentioned previously, non-harmful malware does not exist. And Trojan:JS/KryptoStealer.GA!MSR is not an exclusion. This malware modifies the system setups, modifies the Group Policies and Windows registry. All of these things are crucial for proper system operating, even when we are not talking about PC security. Therefore, the virus which Krypto Stealer contains, or which it will download after some time, will squeeze out maximum revenue from you. Cyber burglars can steal your personal information, and then sell it at the black market. Using adware and browser hijacker functions, embedded in Trojan:JS/KryptoStealer.GA!MSR virus, they can make profit 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 hard to trace the sources of malware on your PC. Nowadays, things are mixed, and spreading methods chosen by adware 5 years ago may be used by spyware nowadays. However, if we abstract from the exact spreading method and will think of why it has success, the explanation will be pretty uncomplicated – low level of cybersecurity knowledge. Individuals press on advertisements on weird sites, click the pop-ups they receive in their web browsers, call the “Microsoft tech support” believing that the scary banner that says about malware is true. It is important to understand what is legit – to stay away from misconceptions when trying to identify a virus.

Nowadays, there are two of the most common methods of malware spreading – bait emails and also injection into a hacked program. While the first one is not so easy to stay away from – you need to know a lot to understand a counterfeit – the 2nd one is very easy to get rid of: just do not utilize cracked apps. Torrent-trackers and other providers of “totally free” applications (which are, exactly, paid, but with a disabled license checking) are really a giveaway point of malware. And Trojan:JS/KryptoStealer.GA!MSR is simply amongst them.
