Hello!
Strangest thing. I was trying to load 4.09 patch and my Avast got hysterical claiming Win32-malware-gen. Same thing in next patch.
A false alarm I am sure, but does anyone else have same kind of a problem?

Yes, it is a know thing. The downloads page (where you downloaded the update from) has a blurb that mentions it, I believe.

I had the same warning from Windows Defender, but I just set it to ignore the folder were the update file lives and all is OK.
