The exact Trojan:Win32/Wacatac.H!ml virus is a very undesirable thing. It digs inside of your system under the guise of something legitimate, or as a part of the program you downloaded from a forum. Then, it makes all possible steps to weaken your system. At the end of this “party”, it downloads other viruses – ones that are wanted by cybercriminals who control this malware. Hence, it is almost impossible to predict the effects of Wacatac.H!ml actions. And the unpredictability is one of the saddest things when talking about malware. That’s why it is better not to choose at all, and don’t give it even a single chance to complete its task.
