Recently I got a fake anti-virus Vista Security 2012. Follow one of the thread at this forum, I was able to remove it by doing system restore to a previous time. The thing is I still suspect that there's hidden rootkit still remains somewhere on the computer. Is there a way to test/remove any hidden rootkit? I have tried TDSSKiller but it returns as "no threat found". I also run malwarebyte but the result is the same.
