I have 2 machines both on XP Pro SP2. The one I use for internet is guarded by Outpost 3.5, KIS 6, Webroot spysweeper 4.5 and Spybost and Spywareblaster for more protection. That is fine as it's been long time I had no infection and it takes resources of the computer as a price for security. The other machine I use mainly for CAD projects and I just connect to the internet for getting windows and few programs updates. I just recently reinstall the windows on a fully formated fresh HD and IE 7 and ZoneAlarm 6.5 and I just used the windows update site to get all the updates. No more internet use and no other programs other than Windows and zonealarm and IE7. After I checked with ZA and I got two low risk rate detections by ZA as spyware treats. Is it a known case with other experienced users as the ZA is not much reliable tool as for a total security solution and should I stick to outpost and an anti-virus like Avira to say and probably a full feature anti-spyware even for those rare occasions to be online on my second machine? I just reinstalled Windows and no ZA yet. Any helpful technical comment is highly appreciated in advance.
