Hi, my nan had McAfee Security Suite 7 and now she bought 2006 8, when I tried to uninstall it says make sure the file is not being used blah blah. I went on McAfee tech chat and he said to delete all the files. I did but two .dll files would not uninstall one was called mcvssl.dll anyway they would not delete, I moved them to the desktop still wouldn't delete so I renamed one, still no luck, I renamed it to:"DIEDIEDIE!!.inf" - notice the .inf. It still wouldn't delete it still says its being used by anothe program. McAfee 2006 8 won't install still. I'm sure it's them two files. How can I delete them?!
