I have trendmicro serverprotect installed on all my servers. there is an information server that checks for updates on a daily basis and updated all the other servers again on a daily basis. last week i had an issue that actuall was a nightmare where an antivirus update was applied on all the servers some of our applications started behaving abnormally. what would be the best and a safe strategy for updating the servers antivirus updates on a limited scale first and then implement it for rest of the servers. what is the strategy that enterprise networks use as part of their antivirus strategy. i just need the best practice.
