Dear ET, please modify the rule for: get.acclivitysoftware.com At the moment rule still generate FP because negation statement is incorrect.

Full HTTP URI for this software is: http://get.acclivitysoftware.com/appcast/us/ae14/win/AEUpdate2014.xml Negation should be like this: content:!".acclivitysoftware.com" Regards.

I added content:!"McAfeeAutoUpdate"; nocase; to get rid of a false with mcafee updates. If we get any others we need to negate I'll have to consider dropping or re-approaching this sig.
