.NET security update false positive

Avast! refused to let me install the following from Microsoft.

Security Update for Microsoft .NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 SP1 for x64-based Systems (KB2943357).

I had to install this while virus protection was disabled. At least once it was installed, Avast! did not complain.

Program version: 2014.9.0.2021
Virus definitions version: 140812-3

OS - Windows 7 Home premium 64 bit

I see that. I did a search, but my search was more specific (.NET update, etc.) and not a generic Windows one.

I’ll improve my search-foo.

/ sorry for the extra noise.
