Hello.  We have Symantec Antivirus Corporate Edition 10.1, and we are experiencing several issues.  First and foremost, we have clients that are not updating definitions from our AV server.  They can stay on all day and as a test we have it set for the installs to look for updates every 5 minutes, but the defs will never get downloaded from the parent server.  We've tried updating both server and client software, but still to no avail.  However, this seems to be hit or miss, because it appears that one out of every 10 or 12 clients will update.

 

Also, we are having an issue uninstalling an older version of SAVCE on a client (it's 10.1.4 and we wanted to update to 10.1.6) but it wouldn't uninstall, saying there was a problem with the installation.  I tried using the Removal Tool, but that said I first had to use Add/Remove programs to remove Symantec AV version 9.x (as I stated before it is ver 10.1.4).  I found the article on how to manually remove SAVCE, but that did not work either as I could not disable Tamper Protection, because it is one of the options that we chose to lock out on the clients (I work for a school and kids tend to mess with things when they get bored).  I tried to change the options for that workstation from the System Center Console, but it said that "Symantec Antivirus could not configure XXX Client Tamper Protection Options".  It sounded like a communication problem, so I tried it on other clients to the same effect...

 

Does anyone have a suggestion as to where we can start?  Thanks!
