It seems from your signature and post that you are now using Avast Pro 6.0.1035

I have never used Avast Pro so maybe the directory path for AvastUI.exe shown in your picture is different than it is for AIS 6.0.1035

Here is the directory path for AvastUI.exe on my computer. Program Files\AVAST Software\Avast\AvastUI.exe

I am not sure why you would have the directory path for the AvastUI.exe in 6.0.1035 shown in your picture.

Does someone know if the directory path shown in the picture is correct?

I would also do search of your HDD to see if you have more than one copy of AvastUI.exe
