Please help, I can't uninstall Avast

Avast Mac Security
1

I tried to install Avast earlier today, but apparently I had another version installed a few years ago. I’m getting an error. “Avast is already installed, please uninstall the previous version first.” But I cannot for the life of me find any remnant of it. Not in the Library logs or applications folder.

I need to install virus protection to sign into my work account and until I get whatever is preventing Avast from reinstalling off my computer, I can’t do that. I’ve tried everything I can find on the forum. This is really frustrating. Please, someone, help?

Hello,
this should fix the problem:

sudo rm -r /Applications/Avast.app
sudo rm -r /Library/Application\ Support/Avast
sudo rm /Library/LaunchDaemons/com.avast.*
sudo rm /Library/LaunchAgents/com.avast.*
sudo reboot

Kind regards,

Hi,

In addition to your list, is there a way to get rid of /Library/StagedExtensions/Applications/Avast.app that is left behind after uninstall process?

Any help is appreciated. Thanks!

Hello,

maybe something like this could help:
https://stackoverflow.com/questions/46535279/what-is-library-stagedextensions-for-and-how-to-remove-extensions
AFAIK that directory contains kernel extensions that are in process of being loaded; I usually see our kext there when it can not get loaded, eg. due to wrong access rights. I guess restart of Mac could maybe also help.
In general it should be irrelevant that it is there; the remove commands I have posted are meant to get rid of some kind of weird remains of Avast AV so that it can be installed again, otherwise follow the official uninstall steps here: https://support.avast.com/en-eu/article/Uninstall-Mac-Security
