This isnt a acceptable solution to uninstall manually.

This is really bad. After upgrading to windows server 2008, Symantec could not be installed automatically. They don't support server 2008 at all. I spent a lot of time manually uninstalling symantec's antivirus, and boy is it a very tedious exercise to say the least.

I'm switching to another anti-virus provider at this point. Too bad that my company spent a lot of money 6 months ago on the corporate license.

Windows Server 2008 is, in fact, supported by both available versions of our AV family, Operating System upgrades, however, have never been supported. Regardless of our software being installed beforehand or not.
If you are having trouble installing to a 2008 machine, verify that you have downloaded the latest available version of Symantec AntiVirus (currently 10.2.3.3000) or Symantec Endpoint Protection ( 11.0.4202). Current release versions can be found by logging on to https://fileconnect.symantec.com , choosing desired language and inputting your serial number.

If you need assistance with any of this process or have additional questions, please call in to support at 1-800-927-4017.

you can use CleanWipe tool - just open a case on Symantec Support and ask them
