toetoe
i use adaware as well as spybot search and destroy
this one can get the ones that adware misses
its free as well

i allso use zonealarmpro which isnt free aslso kerio personal firewall
http://www.kerio.com/kpf_home.html
cant remember whether it was free or not
btw not a good a idea to turn off youre firewalls it leaves you open to too many internet problems If you are using the internet with your network
hope this helps
