Downloaded the OS5.0 beta installer for Windows 64 bit.
FSecure identifies the virus Gen:Heur:Loregun.1 in VirusUpdater.dll.
I am able to update my Virus TI Polar, but I am unable to open up Cubase, as FSecure blocks the VirusUpdater.dll and initiates a clean-up of the mentioned virus.
OS is Windows Vista 64 bit.
