I installed Norton Internet Security recently, and my computer now has long periods of time where it slows down to a crawl. I have an insane amount of RAM and space, so it's not that.

I checked my 'processes' in my task manager and my CPU Usage is at 100%, with CCApp.exe bouncing back and forth between 98% and 99% of that. Did a search for that on my computer and saw it was a Symantec file.

Do I have something set wrong? What's up with this? What can I do?

Thanks in advance!

I posted this somewhere else yesterday. ( Don't remeber where - am new

I installed NIS a few days ago only to find ccapp.exe was hogging 99% cpu ( everything sloooowwwed down and i'd have to end task or re-boot), but not all the time.

Then i realised it only did this when i sent e-mail so i did the thing it says on their website (turn off outgoing mail scanning) and of course it didn't work so i went into the firewall options->programs and removed Outlook Express form the list. No problems since then.

Let me know if it works for you
