While labouring through a full system scan using MalwareBytes Anti Malware, I noticed that it seemed to be spending an inordinate amount of time scanning stuff in this location:
C:\Documents and Settings\All Users\Application Data\McAfee\EasyNet\Thumbnails
I looked in there using Explorer and found there were 10545 folders in this location! All empty! The dates of each folder correspond to days I was working from home - my home network also uses SecurityCenter.
Can anyone tell me what these are for and why there were so many of them? And can I remove them manually?
