I've had to do a restore on my Compaq 705us. 352 Meg Ram, 1 GHz Athlon4. While doing Windows updates before any virus or firewall software, the computer is much faster than it had been. I was running AVG free and Zone alarm free, one or both may have been significantly slowing down this limited computer. I've stopped updates at SP2 with all security updates. Which Virus and Firewall programs would have the smallest foot print (use least resources). All email is online, not download to comp. Computer is used mostly for web surfing but with 352 meg of ram it is very challenging. Any suggestions appreciated, thanks in advance.
