today i bought and installed trend micro PC-cillin antivirus. shortly thereafter my computer got really bogged down and everything took a really really really long time to respond. i pulled up the process manager and it showed 100% of the processor being used. it kept using 100% for a few minutes. i even had to do a forced shutdown because nothing was doing anything. then i ran safe mode and tried to uninstall but i couldnt because i was in safe mode. i ran autoruns and DELETED the registry keys for running the program on startup. then i started normal and everything ran fine except i still cant uninstall. it says "it says this action is only valid for products that are surrently installed." i am running xp with a p4 2.66ghz and 768mb ram.Are you using Windows XP? TRY doing a system resatoration to a time before you installed the software.

FlameYep.. a lot of Anti-virus programs want to lock down your HARD drive for safe KEEPING... And if you have more than one Anti-virus program installed they will tend to FIGHT with each other until you disable one of them. But now that you've gotten it disabled at startup you might try the disc again to see if it will uninstall for you. If not, try running ccleaner... it's been mentioned several times in other posts.What process was using the processor slices?thanks guys but i got it.How did you fix the issue?

FlameI also recommend B Safe Online - it's a great antivirus/firewall program, and it doesn't bog down your system either.

I don't recommend Pc-chiin, Norton, or Mcafee, for Antivirus issues, but I do recommend B Safe.
