hello all! lately i have noticed when i am downlaoding, it takes a while for my preview to show. its like my computer slowed big time. then i notice "thumbs" in my library. it's in red letters. once i delete it, everything works fine. im thinking it's a virus. everything else runs fine though. i ran my comodo anti virus in safe mode but it finds nothing. my cpu usage seems to be normal too. can anyone help me?
