Pc-cillin is a worthy app, especially if you are using XP with only sp1. I just got a new adsl connection at my home and am using xp sp1. I am constantly getting bombarded by trojans, backdoors, rootkits and worms. (LASS expliot especially - i got hit four times while just typing this post). When im online, i see what is coming in and going out, it is like every 5 minutes i get slammed with some type of malware. So this is a bit of a warning to anyone, definately use some type of AV software if you dont have the latest XP security patches installed.
I am running Avast and PCcillin at the same now as a test, they seem to detect the same threats at the same time with no adverse affect on my performance.
I know i should upgrade to sp2, but i dont want to buy a new XP OS until vista comes out. The OS i got now i got from my Acer dealer when i bought my notebook. (came with ME, they could only offer me a copy version XP).
I noticed one rootkit just yesterday installed itself on my system and create a new users (asp.net machine_A). I notice i had a problem because When my machine went into hybernation, my password would not work. I had to reboot.
Microsoft has a free spyware app (defender), but you can only get it if you have a legal copy OS.
I am almost at the point of installing linux, just worried about the driver issue on my piece of shit acer.
