I downloaded a trial version of MacKeeper for my MacBook Pro. I dragged the MacKeeper app from the applications folder into the trash. when i try to empty the trash though it says 3 things:

1. The operation can’t be completed because the item “VersionTrackerAgent” is in use.

2. The operation can’t be completed because the item “TrialPopupsAgent” is in use.

3. The operation can’t be completed because the item “SharedUtils.dylib” is in use.

I cant find any of these! I googled it and all but I found nothing. Help plz!
