avast flagging ATI CCC as rootkit??

when trying to install ATI catalyst control center avast flags it as a rootkit (win32.rootkit.gen [rtk], i think) and won’t let me install. is this just a false positive and if so what are the work arounds for it?

the infection avast detected and blocked during the install was Win32:Rootkit-gen [Rtk]
