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 available tactics. Grabbing your personal data, getting the comission for the ads you watch for them, exploiting your system 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:Win32/RaccoonStealer!MSR detection mean?

The Trojan:Win32/RaccoonStealer!MSR detection you can see in the lower right corner is shown to you by Microsoft Defender. That anti-malware application is good at scanning, however, prone to be generally unstable. It is unprotected to malware attacks, it has a glitchy interface and bugged malware clearing features. For this reason, the pop-up which states about the Raccoon is rather just an alert that Defender has recognized it. To remove it, you will likely need to make use of a separate anti-malware program.

Having Trojan:Win32/RaccoonStealer!MSR malware on your computer is a bad thing from any perspective. The worst issue is that you will not find anything wrong. Key trick of any spyware is being as stealthy as possible. Some Raccoon samples also can perform self-deletion after gathering all the valuable data present on the PC. After that, it will be nearly impossible to recover the flow of events and understand how your accounts were hacked. Variants of spyware that aim at long-term action can target the specific folder in the system or file type. Then, files grabbed in such a way will be put for sale on the Darknet – at one of its numerous forums with stolen data.

Is Trojan:Win32/RaccoonStealer!MSR dangerous?

As I have pointed out earlier, any malware is dangerous. And Trojan:Win32/RaccoonStealer!MSR is not even near of distracting you rather than harming. The most deceptive characteristic of this malware is the fact you cannot witness its activity in any way, other than with the use of anti-malware software scanning. And when you are having no clue, hackers who successfully delivered their nasty thing to your system are starting to count the money. Darknet forums offer numerous opportunities to sell malware logs for a large sum – especially when these logs are new. And you’d better not imagine what will happen to your accounts when other rascals will put their hands on your credentials.

However, situation may have much faster flow. In some situations, hackers are deploying their virus precisely to the user they are trying to steal from. Spyware is priceless when it comes to collecting login credentials, and some samples aim precisely at online banking accounts or cryprocurrency wallets. One may say, giving spyware a run equals to sending all your money to criminals.

How did I get this virus?

It is not easy to trace the origins of malware on your computer. Nowadays, things are mixed, and spreading tactics used by adware 5 years ago may be utilized by spyware these days. However, if we abstract from the exact spreading way and will think about 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 web browsers, call the “Microsoft tech support” believing that the odd banner that states about malware is true. It is very important to understand what is legit – to stay away from misunderstandings when attempting to find out a virus.

Nowadays, there are two of the most common ways of malware spreading – lure emails and injection into a hacked program. While the first one is not so easy to stay away from – you should know a lot to understand a counterfeit – the second one is very easy to handle: just don’t utilize hacked apps. Torrent-trackers and various other providers of “free” applications (which are, exactly, paid, but with a disabled license checking) are really a giveaway place of malware. And Trojan:Win32/RaccoonStealer!MSR is just one of them.

How to remove the Trojan:Win32/RaccoonStealer!MSR from my PC?
