I asked this question at the AVG forum and got no help. I run XP under a limited user account most times. Whenever I wanted to disable AVG's Resident Shield for defragging etc it was possible to use the RunAs command from my limited account to run the control center as an admin and disable it. But with the newer version AVG seems to pick up on the permissions of the logged-in user rather than the permissions granted by the RunAs command, and therefore will not allow changing options. Has anyone noticed if this is true on their pc, and if so, will Avast (free) allow me to do this?
