How do I switch off the 'Scan with AVG Anti-Spyware' shell extension that AVG AS adds to my context menu? I don't need it, I don't want it. It's more of an unsolicited ad - a nagging reminder - than a feature as far as I am concerned. It's like a fifteen second ad you're supposed to watch before you're being served the content you came for. I don't like the way some applications add their shell extensions to your context menu without giving you an option at install time. Some installers have become better, offering users to opt out, but AVG AS apparently doesn't. So, how can I remove this unwanted and unsolicited shell extension?
