I'm running Vista 32-bit SP2 on HP Pavilion. My PC rebooted after a power outage - the UPS didn't shut it down quickly enough. Upon restarting, some of my desktop icons have had smaller icons superimposed, but there appears to be no pattern (jpg's have different changes, pdf, bat & txt are the same). After a while the extras disappeared and all seemed normal, but after I rebooted it this morning, I had a brief reappearance of the unwanted extras in an explorer window - changing the view removed them, but something isn't right.
I've scanned the PC with ESET (with help from the security forum), and my Norton Internet Security 2011 found nothing either. I reviewed the process manager and HJT log but I can't see anything untoward, so I'm fairly certain it's not malware. Has anyone seen anything similar?
