This post - The geek squad
Recently, my sister-in-law took her computer into the Geek Squad (Best Buy), and WITHOUT HER PERMISSION, they removed Avast AV, Comodo Firewall, TeamViewer (remote access software I use to help her at times), and other programs. They activated Windows FW, and put on the substandard Microsoft Security Essentials (note 1). HERE'S THE CATCH, SHE TOOK IT IN FOR A TOTALLY UNRELATED ISSUE.
If you search youtube.com, the Internet, you'll see plenty of horror stories about the Geek Squad (Best Buy). The above, although quickly fixed by me remotely connecting to her computer, after she re-downloaded, and installed Teamviewer, still shouldn't have happened. They screwed her system up, making changes that had nothing, remotely, dealing with her issue.
1. I know that people will disagree with this statement, and that's fine, but in my testing, and research, it proved ineffective.
Have a Great Day!
