trend 2007 100% CPU due to pcscnsrv.exe
This PC is a dual core running slow.
A quick look at task manager shows its due to pcscnsrv.exe using 100% cpu of 1 core.
A quick search finds: http://antivirus.about.com/b/2006/12/02/pcscnsrvexe-performance-problems.htm
So I disable Suspicious Software Alarm System , but the PC is still slow.
About once every few minutes, the CPU would hit 100% for up to 30 sec… and PC would be sluggish.
I started disk defragment and the report shows that it found some log files under c:documents and settingsall usersappdatatrendpccillinlog were quite large (2MB), and consisted of about 150,000 fragments (wow!).
So I didn’t bother defragmenting (it would take too long)… I just renamed the files, & they got re-created. Then, after a reboot, I delete the renamed files
At this point, I do a defragment, and everything was much better… but it still felt slightly sluggish. I can’t be sure that its due to Trend, or if there is another problem.
But the customer is very happy, as the PC is much faster than before my visit.
I suggest that the customer re-installs trend (if they find the PC isn’t running fast enough).
I’m also told that the they also had 2 other occasions where trend went haywire, and they had to spend a few hours on the phone to trend support before the problem got sorted out.
