HOW CAN I TURN AVAST INTERNET SECURITY OFF AND ON WHILE I RUN ANOTHER SECURITY PROGRAM SO AS TO NOT HAVE ANY CONFLICT WHILE I DO??
Disable the shields for e.g. 1 hour.
Hmmm, maybe disabling won’t be enough.
At least, be sure to have a backup or recovery procedures if Windows fail to boot, or login, etc. For instance, be sure you can boot in Safe Mode.
You can totally uninstall Avast, install the other AV and then re-install Avast to run in compatibility mode.
