Title: Cannot reinstall Avast.
Post by: l2vanir2 on April 15, 2020, 11:07:18 PM
Ok. I installed Avast 2 weeks ago but didn't restart the pc after that. I turned off my pc later and the next day I uninstalled it in order to install the premium trial. That wasn't possible to be done though, it always showed me the message on the screenshot. Tried to install the free again, but same message appeared. Restarted the pc many times, but same message again. Downloaded the avastclear to delete completely everything related with avast, restarted the pc again, but it just refuses to install the antivirus. I do not know what else to do.
The message of the screenshot with the weird language just says that "Avast cannot be installed because the pc has not been restarted".

Latest free and premium versions found on the website.
I also use Malware bytes and comodo firewall, but without problems so far.

A Japanese user also reported similar issue, and he is using Comodo too.

For his case, removing these directories manually resolved the issue.
Please make sure you don't have any Avast software installed, or you'll mess your system more.
