I am running windows 7. I have MSE virus protection, Malwarebytes and Supermalwarebytes. Yet, I was the lucky receiver of a Trojan.Ranso which locked my computer and demanded 300 dollars. I was able to do a system restore through safe mode, but am worried about this crap returning. This is just unreal to me, since I have never experienced this before. Anyone familiar with and have any suggestions?
