Win32.Downloader-PKU and Win32.Malware-Gen

system · August 5, 2012, 5:33am

Like so many other posters in this forum, keep getting constant notifications from Avast about Win32.Downloader-PKU and Win32.Malware-Gen.
The location of these (from the avast notification log) is at: C:\Windows\Installer{6cdbd412-545c-88a6-1532-b1548af2b6e8}\U

I’ve attached the OTL log and aswMBR log.
Here’s the mbam log:
