it makes sense, throough scans take a long time(i've got like 140 gigs of info to process) and use alot of cpu, i guess i'll just do it custom if i want to do thorough. i do have four fully functioning fans though and my heat alarm didn't indicate overclocking. perhaps its a driver issue although vista tells me im running the best possible drivers.
i didn't get a redirect like you did to microsoft this only happens when i use avast and do a thorough scan. if it's standard im fine.
