I would also verify with the Geeks who did work on your machine that they did not install or put a trial version of an antivirus on your machine since having 2 AV’s on your system will cause a conflict. If this tech. knew how to look at the Security Center of your machine, he/she would have seen that you did indeed have an antivirus installed (and not too knowledgeable of security software companies ::)), assuming this feature was not disabled, but that was his/her job to “fix” your machine.

As posted earlier, you don’t have to worry about it again. Should you need to bring your machine in again, let them know what you have for security software and not to mess with it. :wink: Or come here first and see if we can fix your problem for you first.
