I have been fighting this Fake Security Alert Center trojan for 5 days ! I finally found the fix at the below website. It has a few steps you have to follow, but it is not very difficult. If an old guy like me can do it, anyone can ! This trojan is a real pain! The worst I have ever seen ! I hope I posted this in the right place and didn't violate any posting rules. If so, please move/delete this. But after all I went through, I felt I had to share this to save other peoples sanity. tnshadows :thumbsup:
