I like avast! and run it on both of my XP systems.did try AVast and its terribly slow, full system scan is excruciatingly painful! ) I can't afford to run it on 256 K Ram
The XP Home system is a 2.4GHZ P4 512MB RAM and is a bit slow.
The XP Pro system is a 2.8GHZ P4 760MB RAM and is quite fast but I think that it is because the hard drive is faster.
256MB RAM is quite low to run XP and RAM is quite inexpensive right now at $28.99 for a 512MB RAM upgrade:
There are other places to buy RAM but Crucial's scanner will let you know what type of RAM you need.
It does take a long time to load for me as well but I only run it after I see that the definitions have been updated.Whats with the current version of Spybot ??
