Hi everyone. I've just got a quick question that's been bothering me for a while. Recently I've noticed some bizarre activity in Win 7 Professional. I run ESET NOD32 v4, and it shows a 'current activity' readout that displays whatever file is being scanned, and thus currently being accessed by the OS or a program. I was watching it while my system was idle, and suddenly it started to scan through the Virtual Store directory. Specifically, it starting to scan through all of my old IM logs from a legacy IM client (Trillian). Now, I haven't even opened that IM client in a week, and the logs it was scanning were over three months old and haven't been altered since.
I ran a scan with NOD 32 v4, Windows Defender, and MalwareBytes antimalware. All of these came back clean with no infections/intrusions detected... But I can't think of any reason why three-month old files from a program that hasn't been run in a week would be accessed at all, other than a rootkit virus or something hidden poking through my personal correspondence.
Is there some reason that Win 7 might be accessing these file for some other purpose? I don't have automatic backups set up, and it looked pretty specific that the disk activity leafed through that specific folder and then stopped dead without looking at anything else.
Any advice would be appreciated. Thanks.
