If you spectate the notification of Trojan:Win32/Blister detection, it seems that your system has a problem. All malicious programs are dangerous, without any deviations.

Any kind of malware exists with the only target – make money on you1. And the programmers of these things are not thinking of morality – they use all possible methods. Taking your personal data, receiving the comission for the banners you watch for them, exploiting your system components to mine cryptocurrencies – that is not the full list of what they do. Do you want to be a riding horse? That is a rhetorical question.

What does the notification with Trojan:Win32/Blister detection mean?

The Trojan:Win32/Blister detection you can see in the lower right corner is shown to you by Microsoft Defender. That anti-malware software is good at scanning, however, prone to be mainly unreliable. It is unprotected to malware invasions, it has a glitchy interface and bugged malware removal capabilities. Thus, the pop-up which states about the Blister is rather just an alert that Defender has actually recognized it. To remove it, you will likely need to make use of another anti-malware program.

The exact Trojan:Win32/Blister infection is a very unpleasant thing. It is present inside of your computer disguised as a part of something normal, or as a part of the tool you downloaded at a forum. Therefore, it makes everything to make your system weaker. At the end of this “party”, it injects other viruses – ones which are wanted by cyber burglars who manage this virus. Hence, it is impossible to predict the effects from Blister 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 let the malware to complete its task.

Is Trojan:Win32/Blister dangerous?

As I have pointed out previously, non-harmful malware does not exist. And Trojan:Win32/Blister is not an exception. This malware changes the system setups, alters the Group Policies and Windows registry. All of these things are vital for correct system operating, even in case when we are not talking about Windows safety. Therefore, the virus which Blister contains, or which it will inject after some time, will try to get maximum revenue from you. Cybercriminals can steal your personal data, and then sell it on the Darknet. Using adware and browser hijacker functions, built in Trojan:Win32/Blister malware, 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 difficult to line the sources of malware on your PC. Nowadays, things are mixed, and distribution ways used by adware 5 years ago may be used by spyware these days. But if we abstract from the exact spreading tactic and will think of why it works, the reply will be pretty simple – low level of cybersecurity awareness. Individuals press on advertisements on weird websites, click the pop-ups they receive in their browsers, call the “Microsoft tech support” believing that the strange banner that states about malware is true. It is important to recognize what is legitimate – to stay away from misconceptions when trying to figure out a virus.

Nowadays, there are two of the most extensive ways of malware distribution – lure emails and injection into a hacked program. While the first one is not so easy to evade – you need to know a lot to recognize a counterfeit – the 2nd one is very easy to get rid of: just don’t use hacked apps. Torrent-trackers and other providers of “totally free” applications (which are, actually, paid, but with a disabled license checking) are really a giveaway place of malware. And Trojan:Win32/Blister is just one of them.
