My 3 PCs are on a home wireless network and run XP SP3. For protection I
use Avast antivirus, ZA free and do frequent checks for malware (Ad-Aware
and Spybot). My internet access is high speed via a router using COX.

In my area Cox is now offering a free download and use of McAfee Security
Suite to its customers. Should I replace my present Avast and ZA with the
free McAfee suite? I've heard that McAfee can be a hog on resources and
slow down the PC.

Recommendations?
