used AVG and spybot side by side for years. AVG has made some fairly recent changes that make it more difficult to control (you can no longer just turn it off like you could before). after a recent, very aggravating night of trying to install a program that AVG kept blocking, i was forced to uninstall AVG in order to install my program. i installed MSE and will be switching all my machines over shortly. i HATE when an antivirus starts to act more like the virus' they are meant to protect me from for firewalls i am behind my routers hardware firewall and i always run windows' built in firewall.
