I think to use Avast4 I have to buy a P4 2+ with at least 256 MB RAM :‘( :’(

well, I think you are over reacting on this one…a PIV needed to run Avast4 ?

I have a PIII 1 Ghz with 384MB Ram under XP, and I have NO problems at all. No slowdown, no crashes…

A PIII is not a “state of the art” processor anymore (pc is 2 years old) but Avast (with all providers running) runs like a sport car.

I also have “Zone Alarm Pro 4.0” and “Anti trojan 5.5 guard” running resident (ALL the time).
and also this little program to free up RAM ( cyber lat ram cleaner) www.cyberlatino.com.mx
