guitar riff,
I have had exctly the same problem in the last week except for me it was with another sponsors links.
I've tried Adaware,Spybot Search and Destroy and
http://www.doxdesk.com/parasite/
All to no avail,each search returned a PC clean bill of health
It was suggested to me by Matt from
http://www.pinknpurple.com/ that I try this program .
http://www.spywareinfo.com/~merijn/ the program is called hijack this .
I tried it and It found entries in my registry files that caused my pc to be redirected to R@PE pages and other sites totally unrelated to my search.
Within minutes I had removed the malitious files and rebooted my pc and was back in the saddle.
Also An antivirus program will not detect these as they are not a virus...
I hope this helps as it did me.
Regards,
Wicked1
