I'm quite a newbie and I'm not really that good with computers eather so I may ask some lame questions... I have a Pentium III 800 mhz and I'm wondering what software I should use that take up little memory and Defend me against viruses, trojans, adware,spyware etc. I am currently using Nod32 as an anti-virus, Zone Alarm for the firewall, TDS for trojans and MS antispyware. Do you think I could find Some that are better and take up less memory? Please HELP! SOS!
