Even though System Mechanics does not show anything, it sounds as though the malware has indeed arrived.
Here is a malware hunter procedure that Grif suggests : http://forums.cnet.com/7726-6132_102-5098912.html?tag=posts;msg5165373
That should get even the most stubborn ones but maybe not all. One could try one of these, also: http://antivirus.about.com/od/freeantivirussoftware/tp/avrescuecd.htm
The problem started when I clicked on an image in google images. The computer shutdown immediatly and when I restarted it I got the notice that it had shutdown badly and options of starting in safe mode or normally. I started it normally and system repair ran. I finally got it started and everything seemed fine until I left it in sleep mode. When I came back it had shutdown and I had the same problem starting it. This has happened several times. If I shut it down and restart it is fine. I have System Mechanics Pro and scanned for malware and found none. Now when I search on google I am being redirected to other websites every third or fourth time. What do I do?
I have a Dell Inspiron 1545 with Windows 7 - 64 bit. I'm not a computer guy and don't know the tech terms to describe my problem.
