#8 for effectiveness
#10 for light resource usage
Bought AVG 7.5 IS suite three months ago and haven't looked back. It's Antispy scanware, formerly the excellent Ewido, uses 40-85 percent resources on this rig while actively scanning, just as they all do and less than some products. It's light antivirus and firewall resource usage don't slow this down like the other IS suites I bought in the past: Norton System Works and it's brother Symantec IS, and Zone Alarm Pro.
All together AVG IS suite uses about 51MB of RAM here when not scanning, that's real good.
A couple of other antivirus like Kaspersky and NOD32 may be higher rated, but using AVG antivirus free, and now paid for, for 3 years has never let me get infected, it's pretty durn good.
AVG 7.5 Firewall is basic and easy to set up and use -- real "Danger-Surfers" might like a firewall with more options but this one suits me fine, no intrusions.
My only complaint is the eMail scanner is a little slow, it takes two or three seconds for each.
I use SuperAntiSpyware as a second scanner because one will catch what the other might miss.
Overall it's very good, you'll like it
