Be aware of Trojan.Ransomware which trickily pretends to be an installer for Adobe Flash Player software, but in reality it’s just a tool to perform an SMS fraud!
When executed, Trojan.Ransomware will make a copy of itself in %ALLUSERSPROFILE% and then will start displaying notifications in Russian. Usually, Trojan.Ransomware performs fake Adobe Flash Player installation that requires sending an SMS message to receive a certain activation code and to complete installation process.
However, this process is not real, so you should remove Trojan.Ransomware after noticing messages looking such as the picture given below. When deleting, try serial codes 35676549 and 28527548 and also run Spyware Doctor anti-spyware.
