Symantec. Just ran a full scan yesterday. Found one problem, which was supposedly removed.
You might want to turn off the indexing service. That can get things wrapped around the axle.
Symatec. That is your problem. It is a crap program. Uninstall it. Install better anti virus. Crap AV includes Symantec, AVG, McAffee. Try Avast. Have had good luck with it.
That's likely at least half your problem.
