Hi,
I have been using Avast Free for some time. Recently bought IS 2014 and install; the problem since day one was that the AvastUI.exe was not starting up post restart for some reason. I always had to manually run it.
I searched the forum and tried all the solutions,
Repair did not help.
uninstall and re-install did not help.
Downloaded avast utility and ran it from safe mode; no success.
I thought of creating my own run entry for AvastUI.exe /nogui in registry. So when I looked in to regedit; to my surprise the existing entry was not there. It should be at HKLM\Software\Microsoft\Windows\CurrentVersion\Run, but it wasn't.
So I checked the 32 bit view of registry for the key, HKLM\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Run and indeed the entry was there.
So I created an entry in the 64 view, HKLM\Software\Microsoft\Windows\CurrentVersion\Run (just copied it from the 32 bit), did a restart and first time since I installed avast; it worked.
So if you are facing same issue; this is worth trying.
Thanks
Aditya
