how to uninstall avast using avast removal tool AVASTCLEAR.EXE Utility
One of the issues with all anti-virus vendors is leftovers from previous versions. To rule out this as the point of failure, I recommend a clean installation. This is a requirement when migrating from avast! consumer versions (Pro, I.S., Premium, free) or legacy Endpoint Protection to the cloud version. There are several ways to accomplish this task:
DOMAIN – If you have a Domain and are currently using legacy avast! Endpoint Protection Suite / Plus, then you can use group policy to deploy AVASTCLEAR.MSI –

UNINSTALL – Uninstall the existing avast!, reboot, and delete the “AVAST Software” folders under “C:\Program Files” and “C:\ProgramData” Microsoft uninstaller always leaves the old directories for the purpose of System Restore. Go look, every program you have ever uninstalled is still there!
REMOVAL TOOL – The last option is to use ASWCLEAR.EXE process described below.
NOTE:
ASWCLEAR.EXE supports all avast! versions, including consumer (Free, Pro, Internet Security, Premier) where
AVASTCLEAR.MSI is for Endpoint Protection ONLY!
Download the avast! removal tool:

Next step is to clear the checkbox “Enable avast! Self-Defense Module”. This prevents one from having to run the avast! removal tool in safe mode!
Disable Self Defense Module NOTE: When the Self Defense Module is disabled, then you
DO NOT RUN “ASWCLEAR.EXE” IN SAFE MODE
You must acknowledge “Yes” to fully disable the avast self-defense module:
uninstall avast anti-virus by running “ASWCLEAR.EXE”
NOTE: DO NOT RUN “ASWCLEAR.EXE” IN SAFE MODE: click “NO”
NOTE: DO NOT RUN “ASWCLEAR.EXE” IN SAFE MODE: click “NO”
On this screen, you will have to choose the version of avast! that we just un-installed. NOTE: If you did NOT change the default location during installation, then you may leave / ignore the top 2 locations as “unchanged” If multiple different avast! versions were installed, you may close and reopen ASWCLEAR and select a different version. I have done them all before when unknown.
Reboot the system after ASWCLEAR, and now you can “clean” install. Rarely, I have used this problem to replace corrupted installs
Please let me what I can do to help, and have a great day!
