What is Trojan.LockScreen?

Trojan.LockScreen is an especially dangerous cyber threat that belongs to trojan horse category. However, it can also be categorised as ransomware because it acts as the optional component of these cyber threats. Mostly, this infection comes inside its target PC system undetected. Once inside and active, this trojan horse starts playing one of the most important roles in the functionality of Ukash and Police virus.
