Since no real workaround has been suggested by Avast! brightest I will post the workaround I now deploy on my various PC’s in regards to the “openvpn.exe” flagging by in this case PSI from Secunia.
It basically involved purging my Avast! installation of the SecureLine add-on. Get that bit of “bloatware” of the PC and the flagging will stop.
Mind you I state “bloatware” maybe a bit harshly as Avast! has included alot of additional software many may not fully use to it maximum but remain to this day part of the default installation.
I know I would not use SecureLine simple as there are other VPN-services out there that seem to take better care of their service then what I now see from Avast! “added” value.
Basically I am saying “SecureLine” is OpenVPN but then recompiled by Avast! but behind on updates,options and/or added features.
If I were to use OpenVPN software I would get it directly from OpenVPN.net itself and get the latest (fixed) version of this software.
