Title: Help uninstalling Avast completely
Post by: inchyrablue on February 09, 2022, 11:12:53 AM
Hi there,

Wondering if someone can help me resolve this:

- My Macbook pro crashed part way through installing Avast One for Mac (it had never previously crashed and is a 2021 model)
- Once rebooted, Avast looked as if it was installed but wouldn't open. This meant I could not access the built in uninstaller
- I uninstalled by deleting Avast from applications
- I can't reinstall Avast as it returns the error: 'avast is already installed, please uninstall the previous version first'
- Since that time, I have had continuing problems with crashes. These may be unrelated to the above, but I would like to make sure I've fully uninstalled Avast.

Any help gratefully received.

Sorry - but that seems to lead me to the general 'how can we help' avast support page?

Thanks for this - but it doesn't help in the case I described. First - I was never able to open Avast, presumably as it had crashed mid way through installation (therefore I didn't have access to the built-in uninstaller).

Second, owing to the above, I deleted the app from the applications folder by putting it in the trash..

So it looks as if Avast is not installed - but when I try to reinstall it, it tells me it is.

Any other suggestions?

I've alerted Avast to your plight.
Let's see what they can provide.

To my knowledge there is no standalone uninstall tool.

Try starting the Mac in Safe Boot mode. Restart the Mac and immediately press and hold the shift key. Release shift once the login screen appears. This prevents most extensions from loading that may have interfered in the install process. Now reinstall Avast and then reboot without pressing any keys to get back to normal mode.

Hopefully you have a fully functional copy of Avast at this point, and if still needing to uninstall can use the built in uninstall procedure that was already linked to

Here's what Avast suggested:
Hi, open Terminal and type sudo rm -r /Library/Application\ Support/Avast  (confirm with Enter) and then reinstall Avast

Explanation: The crashed installation left some files in that directory and the new installation refuses to install, because it thinks the Avast application is already present - but in reality, there are just some leftovers from the crashed installation. If the leftovers are deleted by the command above, the application can be reinstalled as usual.

Thanks for this - it is now allowing me to progress the install.

With this said, do you think I should be installing Avast given the fact it seemed to cause the crash last time (which I think is a kernel panic?)? Specifically - is this a known issue?

Title: Re: Help uninstalling Avast completely

Hello,

from the provided panic report, this is the important part

Kernel Extensions in backtrace:

This is the driver that caused the kernel panic. Avast is not involved in this. We do not even have a driver loaded in your macOS (the full listing of drivers was part of your report as well).

I would assume this was a one-time issue due to some bug in the driver. It should not affect your ability to install Avast if you are able to boot the macOS. Of course a faulty driver can cause multiple similar panics in the future.

Kind regards,

Jakub
