Now this is wierd stuff. I downloaded a .avi file some time ago. Nothing to worry about. Until I decided to clean up my HD a bit. I deleted some files. Still nothing wrong, until I tried and deleted this particular .avi Every time I merely click on the file, my HD starts spinning like crazy, my system slows down to the point of being completely unusable and the only way to recover from it is a reset. I'm unable to delete the mentioned file no matter what I try! I've tried Norton utilities...I've tried to put it first in quarantaine (sp?) with Norton Antivirus before deleting it (a surefire way I've used before to get rid of more "persistent" files)....nothing gets the job done. Does anyone know what's wrong here, or what might help?? Thanks P.s. Right, I forgot. I scanned the whole system for viruses with the latest virusdefinitions....nothing found.
