My PC has been slowing down gradually over several months, which I now seem to have tracked it down to VSSERV.EXE as the culprit !
I'm running Total Internet Security 2011 on XP, fully up-to-date, XP also fully up-to-date, PC had been regularly de-fragged and Registry cleaned.
I can no longer run a full virus scan as It gives me rediculous estimates, such as 68 hours [almost 3 days].....and after 5 hours of scanning, often scanning < 1 file/second, it probably is an accurate estimate.
On a 2GB, P4 2Ghz PC, running nothing other than the antivirus scanner, this is REDICULOUS !
Help would be appreciated, before I totally loose it & instal a free AVG !
