Mcafee Webshield for smtp update.

Well I still stand by my opinion that the software is rubbish, but I've tracked down the main problem. I removed the software and reinstalled (without the hotfix) and everything worked ok. Installed the latest antivirus dat file - cpu goes up to 100% and emails do not get forwarded to our server. Remove, reinstall and everything seems ok. Changed the ip address to be a static machine, thinking everything was good - bang - same thing. Removed, reinstalled everything is fine. Installed av update again (just to check) - bang. Now on my *final* removal/install. Hopefully I can set the update to *never* update as I'm not using it for antivirus scanning anyway. Now allegedly the hotfix that I really need to apply should fix issues similar to this but it obviously doesn't from the frustrations voiced yesterday.
