The installer triggerd my (crapy) antivirus, etrust 8.1 with VET engine and latest pattern, it reported a Virus:
The Win32/Rewas!generic was detected in C:\USERS\MyUser\APPDATA\LOCAL\TEMP\PDNSETUP2\MIRRORSHIM.EXE.
Machine: blabla, User: domain\MyUser.
Status: File was cured; system cure performed.
I'm affraid this is a false possitive from my Antivirus, still I wanted to mention this.
