I recently installed WormGuard trial version on my XP 2 system I have McAfee AV, McAfee Firewall, MailWasher, Counterspy, Spybot [might as well be a paid for prog its great] and Spysweeper, all paid versions along with Sitehound trial version. Wormguard installed without difficulty and appears to be working fine. I run CyberScrub as a clean up tool. The only difference I have noticed is a need to reboot my Belkiin router on startup. This may not be down to WormGuard but I was wondering if anyone else has any ideas. I have never tried to uninstall WormGuard and so have not experienced the problems being faced by some on this forum. Seeing that I have not had problems since installing WG I wonder if the problems of others does not rest with WG but with other programmes they have installed. hitbit.
