Uninstalling Symantec from Clients Remotely

From what I've read, Symantec management tools only have a way to install or change features, but not uninstall it from clients. I read a couple other forum posts, but none with solutions to my problem. I HAVE gone to Symantec's site and it gives three ways of uninstalling for multiple clients. The problem is the only possible solution they presented was through group policy, but because we didn't implement it that way, we can't uninstall it that way. And it'd be ridiculous to have to go manually uninstall Symantec from over 200 computers.

Please help!
