WS.Reputation.1 *!?!@@@!?!

Lately this warning has been coming up more and more frequently, to the point where I'm getting these stupid false positives several times a day. So I added "WS.Reputation.!" to my Signature Exclusions list, but I'm still getting these damn warnings! When is Norton going to fix this problem? If something isn't done soon, I'm just going to uninstall this crapware and get some other anti-virus program.
