My Asus/Vista64 laptop annoyed me. For some reason Firefox was unable to connect to the net. One day it just stopped working. After some mucking about I found out it was caused by some Anti-Virus Software that came with the computer.
I deactivated the AVS, installed Microsoft’s free Security Essentials and problem solved. This reinforces my belief that AVS is largely redundant if you exercise some caution. As a bonus, the computer runs much better now.
I still like my Macs better, but I don’t consider Windows Vista to be the suckfest it is generally made out to be.
