Norton 2012 says AMD Catalyst driver is a threat

I have just downloaded the latest AMD Catalyst 12.6 beta driver from AMD website. I always disable my antivirus before updating drivers. As soon as I reboot and I turn on my antivirus, I found out that it has quarantined atiumdag.dll file from SysWOW64 folder, and I can't run any game. Norton says that it containts threat "Suspicious.Cloud.7.F"

 

I'm using Windows 7 x64. Please fix it as soon as possible, for now my antivirus has to remain disabled.
