I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Does it look like the hard drive is being highly utilized or what's the CPU utilization?  Our company went with SEP from SAV and I totally hate the scheduled scans.  My computer becomes completely useless during the scheduled scan.  When I investigated, the hard drive was being highly utilized.  Used Sysinternals' file monitor.
More than likley rtvscan.exe is using upwards of 50% of the CPU.......SEP is an app that is very heavy on resources.

Are you doing the scans after hours?

Also you can think of upgrading to the SEP 11.0 RU6. This is the latest revisiion update. Please check this link, this version includes new scan features for performance optimization.
