If there is anyone here using this program are you as happy as I am with it ? I used to use norton AV but one day I was looking through the CD that came with my Iwill KK266 I saw that it came with PC-cillin 2000. So after doing some research I found that it was certified for Win2K, so I gave it a try. Well I must say that it does not bog my system the way Norton used to, it performes full scans faster than Norton and virus Def. updates seem to be every 2-3 days. It also scans e-mail, and active X programs. I would recomend anyone giving it a try.
