UAC prompt on startup

Hi all,

I’m looking at some problems on my mother’s laptop (using Windows 7 64-bit Home Premium) and I’m noticing that each time the laptop boots up, there’s a UAC prompt showing up, asking me if I want to allow this program to make changes:

“C:\Program Files\AVAST Software\Avast\AvastUI.exe” /nogui

Being a good forum user, I searched to see if anybody else had this problem and came across this thread which had a RESOLVED tag on it. However, on reading it, the solution in that thread wouldn’t help at all. Yes, it’d get rid of the UAC prompt, but only because it would stop the UI from even running in the first place. Obviously, I don’t want that - I want the UI to be able to run.

I should note that I don’t get any prompts on my own laptop, which is Windows 7 64-bit Professional. (Our use cases are quite different and it’s quite possible she’s done something to cause this to happen, but I’m sure that it would have been by accident and not deliberate.)

I haven’t yet tried to Repair Avast as detailed in the thread. I’ll do that as soon as I post this, and if that doesn’t work then I’ll try uninstalling and reinstalling, unless anybody’s replied in the meantime. I wanted to post this thread to see if anybody else had come across this, and to let people know of any solution when I get to it.

(For the record, turning UAC off is not an option here. That would be a workaround and not a solution.)

[edit: Something came up and I need to postpone this for tomorrow. In the meantime, if anybody has any ideas, I’d be interested to learn them!]

This could be related with Windows Defender.
Is avast set as legit into the startup manager of WD?

I havn’t looked at my windows defender in such a long time but i dont think the startup functions are in windows 7 defender Tech ??? vista was able to do that from memory

Maybe a simple repair and reboot could solve the start up of avast. If not, then uninstalling, reboot, installing again and reboot should take out the wrong initial start up line.

If you use Avast Pro or Avast Internet Security, you should backup your avast license file before uninstalling, so you can apply it later again.

Please don;t skip the reboots, as they are necessary to solve the initial start up lines.

Please report back.

As far I remember, WD control the startup items (and it is what the user is experiencing).

The manifest inside AvastUI.exe says that the program does not need elevation… so Windows certainly shouldn’t show the UAC prompt, unless something else is involved.

I’m really sorry that I never responded back to this!

I’ve managed to get a chance to work more on her computer, and I found the issue. It turned out that for some reason, the Compatibility flags on AvastUI.exe were set such that it was trying to be compatible with XP SP2! I turned that off, and things should be fine from here on in.

Again, I’m incredibly sorry about not responding back. I honestly hadn’t had a chance to work on her laptop again until now.
