Any type of malware exists with the only target – generate profits on you1. And the developers of these things are not thinking of ethicality – they use all available ways. Stealing your private data, receiving the comission for the advertisements you watch for them, exploiting your PC to mine cryptocurrencies – that is not the complete list of what they do. Do you want to be a riding horse? That is a rhetorical question.

What does the pop-up with Trojan:HTML/CryptoExtortBTC.A detection mean?

The Trojan:HTML/CryptoExtortBTC.A detection you can see in the lower right corner is displayed to you by Microsoft Defender. That anti-malware application is good at scanning, but prone to be mainly unstable. It is unprotected to malware attacks, it has a glitchy interface and problematic malware removal capabilities. Hence, the pop-up which states about the CryptoExtortBTC is rather just an alert that Defender has found it. To remove it, you will likely need to make use of a separate anti-malware program.

The exact Trojan:HTML/CryptoExtortBTC.A virus is a really nasty thing. It sits into your PC disguised as a part of something normal, or as a piece of the program you downloaded at a forum.

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

Is Trojan:HTML/CryptoExtortBTC.A dangerous?

As I have actually mentioned previously, non-harmful malware does not exist. And Trojan:HTML/CryptoExtortBTC.A is not an exception. This virus modifies the system settings, edits the Group Policies and Windows registry. All of these elements are critical for correct system operating, even when we are not talking about Windows safety. Therefore, the virus which CryptoExtortBTC contains, or which it will download later, will squeeze out maximum revenue from you. Crooks can steal your personal information, and then sell it at the black market. Using adware and browser hijacker functions, embedded in Trojan:HTML/CryptoExtortBTC.A malware, they can make money 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 trace the origins of malware on your computer. Nowadays, things are mixed up, and distribution ways utilized by adware 5 years ago may be used by spyware these days. But if we abstract from the exact distribution way and will think of why it has success, the explanation will be very uncomplicated – low level of cybersecurity knowledge. People click on promotions on strange sites, click the pop-ups they get in their web browsers, call the “Microsoft tech support” assuming that the scary banner that states about malware is true. It is necessary to know what is legitimate – to stay away from misunderstandings when attempting to identify a virus.

While the first one is not so easy to avoid – you need to know a lot to understand a fake – the 2nd one is easy to get rid of: just don’t use cracked applications. Torrent-trackers and other providers of “free” applications (which are, in fact, paid, but with a disabled license checking) are just a giveaway point of malware. And Trojan:HTML/CryptoExtortBTC.A is simply within them.
