I'm currently running Norton Internet Security 2006 + WinPatrol 18.104.22.168 on XP (2.13 GHz, 512 MB of RAM) through DSL on direct modem connection (tweaked settings + manual system services, etc). Can someone recommend a good program to run alongside my current configuration? RegDefend, Prevx1, Process Guard, Online Armor, RegRun, Ewido.... Not sure what program of the above is recommended. I'd like to ONLY install ONE due to the fact that I'd like to keep my system's speed and performance in tact. Any suggestions/help/recommendations would be greatly appreciated. Thanks.
