With Firefox, and McAfee SiteAdvisor as my Browser and Guide, I'm not sure I really need a resident Antispyware. I have never been hit with Spyware, or a Virus using Firerfox, and I think that Arovax Shield is enough for the average safe surfer. It covers some important areas of the PC, is low on resources, and stops many Firefox cookies to boot. I believe Arovax Shield along with AVG Free 7.5 and Windows XP Firewall would be a very good and safe low resource combo, and even safer with a Router Firewall added. Then maybe add in AVG Anti-Spyware Free and SuperAntiSpyware Free as on demand, and your good to go. All these extra programs running like, Third Party Firewalls,CIPS, HIPS, and Resource using Antispyware programs just slow down the PC, and what do they really prevent if your a Safe Surfer who never gets hit with anything to begin with?
