I see a wealth of info on here concerning antivirus programs.It's time for me to buy another 1. I think all of these i have listed are great--they are close to the same price and use low resources.I didnt mention kav for the fact i want low resource usage. F-prot seems to be gaining on the big boys--so i read --Nod 32 is always trying to improve with great forum support. Now Dr.web is maybe my first choice--from what i read it seems to keep up with kaspersky---and thats amazing seeing that it uses much much less resources--but i don't think it is user friendly--just don't know. I would just like to read which program you are using and how you like it--does it run smooth with xp pro with latest patch upgrade? thx guys----i hope asking questions like this has not been beat to death here.
