Avast detects Kaspersky and won't install
« on: October 28, 2018, 12:24:58 PM »
I have used the uninstall tool from Kaspersky and even had a support call with them where I sent log files that states there is no instance of their software loaded.

Avast for Mac (free version initially) still won't install as the installer says it detects Kaspersky.

I'm stuck.

Hello Moyners,

Avast detects conflicting software based on KEXTs (drivers) loaded into kernel. You can list the drivers by opening and typing 'kextstat'

If there is any of the following IDs in the listing, it is detected as Kaspersky:

If you have correctly uninstalled Kaspersky but the driver remained there, a reboot should resolve the issue. Alternatively you can run in

sudo kextunload -b <id of the bad kext>

This will try to unload the driver without rebooting. You can check with kextstat whether it worked.

If you can't install Avast even after removing all of Kaspersky drivers, please provide us with the output of kextstat command to take a closer look.

Best regards,
