Hi, After reading this great forum for a couple of months, I tried to rebuilding a defense for my little notebook. I am using Fujitsu Lifebook P2040 as my main PC and I carried both on work and home. My P2040 Spec is: Crusoe 800Mhz, 60 Gig HD, and 240 Meg Memory (Some was taken by Video Card). I bought NOD32 couple days ago as starting point. Now my system have: 1. Antivirus: NOD32 2. Firewall: ZoneAlarm Free 3. SpywareGuard (maybe I will take this down for better SW replacement). The problem is I read too much on this forum and feel that I need more layer for my defense. I do a lot of searching on the internet. So which next software should I acquired I am thinking to buy AT Software. TDS3 seem to heavy on memory side. I am not sure with BoClean since I could not try it out. How about PG?? I need to reserve my memory as much as I could. Any suggestion Thanks a lot.
