knobby - just saw your post.
As you know, deleting or uninstalling anything doesn't physically remove anything from your pc. It just means the space it occupied on your hard drive is available to be written over. This can take a long, long time. So it is still there. Lurking. But hopefully inactive. If your pc is running well, and you continue to run your security regularly you have nothing to worry about.
Every six months or so, I turn off system restore, start my pcs in 'safe mode' and run the security programmes. This makes sure that anything hiding in system restore is also got rid of. But don't get paranoid!
