Any type of malware exists with the only target – generate profits on you1. And the programmers of these things are not thinking of ethicality – they utilize all available ways. Stealing your personal data, receiving the payments for the ads you watch for them, utilizing your system 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:JS/BlacoleRef.CZ detection mean?

The Trojan:JS/BlacoleRef.CZ detection you can see in the lower right corner is shown to you by Microsoft Defender. That anti-malware application is pretty good at scanning, but prone to be basically unreliable. It is vulnerable to malware attacks, it has a glitchy user interface and problematic malware clearing features. Therefore, the pop-up which states about the BlacoleRef is just an alert that Defender has identified it. To remove it, you will likely need to use another anti-malware program.

The exact Trojan:JS/BlacoleRef.CZ virus is a very nasty thing. It sits inside of your PC under the guise of something legitimate, or as a piece of the application you downloaded from a forum. Therefore, it makes all possible steps to make your system weaker. At the end of this “party”, it injects other malicious things – ones which are choosen by cybercriminals who manage this virus. Hence, it is impossible to predict the effects from BlacoleRef 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:JS/BlacoleRef.CZ dangerous?

As I have stated previously, non-harmful malware does not exist. And Trojan:JS/BlacoleRef.CZ is not an exclusion. This malware changes the system setups, modifies the Group Policies and registry. All of these things are crucial for proper system operating, even when we are not talking about system security. Therefore, the malware which BlacoleRef contains, or which it will inject later, will try to get maximum revenue from you. Cyber burglars can grab your personal information, and then push it on the Darknet. Using adware and browser hijacker functionality, built in Trojan:JS/BlacoleRef.CZ 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 hard to line the origins of malware on your PC. Nowadays, things are mixed, and distribution ways chosen by adware 5 years ago can be used by spyware these days. However, if we abstract from the exact distribution method and will think about why it works, the reply will be pretty basic – low level of cybersecurity knowledge. People press on advertisements on strange sites, open the pop-ups they receive in their web browsers, call the “Microsoft tech support” thinking that the weird banner that states about malware is true. It is necessary to know what is legit – to avoid misunderstandings when attempting to identify a virus.

Nowadays, there are two of the most common methods of malware distribution – bait emails and also injection into a hacked program. While the first one is not so easy to avoid – you need to know a lot to recognize a fake – the 2nd one is simple to handle: just don’t use hacked apps. Torrent-trackers and various other providers of “totally free” applications (which are, actually, paid, but with a disabled license checking) are really a giveaway point of malware. And Trojan:JS/BlacoleRef.CZ is just among them.
