I have implemented Mcafee Webgateway 7 after implementing i am unable to update any antivirus in my entire LAN system.If i remove the Mcafee from my network then its working fine. Do anybody have any idea about it.
First it would be a good idea to gather some information about the problem. I would start by checking out the access logs (Troubleshooting > Log Files > user-defined-logs > access.log > access.log) to see what destination your AV updater is trying to contact. Then you can try bypassing for that specifc URL, or trying other things.
