Antivirus Free some strange problem with license

[REDACTED]

Hello.
Recently I have been watching a strange things with a license issue.
Sometimes Anti-Virus on the first (clean) installation is automatically activated and does not require e-mail.
Very often after complete removal in safe mode and after running Avast utility avastclear the license information remains on the computer and it is impossible to re-register.need to wait when the license expires.
It was noticed on Windows 7 and 10.
sorry for my bad englihs,thx to google:)

Yes this might happened as we deliver the license based on machine ID so you might get the same valid (might be expiring) free license.
