Windows заблокирован! Ransomware (Uninstall Guide)

Tell your friends:
Windows заблокирован!

Microsoft Security обнаружил нарушения использования сети интернет.
Причина: просмотр нелицензионного гей и детского порно.
For those of you unfamiliar with ransomware -- it's a kind of malware with a particularly nasty payload. Windows заблокирован! Trojan ransom blocks software and asks for a ransom in exchange for releasing control of your computer. It gives instructions on how to send 200 Hryvnia (UAH) via WebMoney to free the computer. Hryvnia is a national currency of Ukraine. This scheme is very popular in Russian too. Ransomware can be spread in several ways but usually cyber crooks use fake pornographic websites to distribute the "Windows заблокирован!" and similar malware. In this case, Trojan Ransom claims that you were watching illegal pornographic videos (as usual) and if you won't pay the ransom your files will be deleted. But that's not all, if you choose not to pay the fine they will notify the authorities and your case will be handled in a court. Of course, that's not true. Don't worry about that. If your computer is infected with the Windows заблокирован! ransomware, please follow the removal instructions below. Good luck and be safe online!
