I have just booted WinXP with Avast Free 18.5. Definitions were updated OK.
The Avast UI screen states Licence will Expire in 3days at the bottom.
I have hit the "Extend" button and from that chosen Avast Free option. Then exited the next page that offers upgrade at discount.
The problem is I still see the "Licence will expire in 3 days" warning, despite attempts to extend it.
I thought Avast Free was not time limited.
Anyone else seen this and overcome the licence extension loop?
Also seen this previous post re v18 Licence expiry from @NON.
After testing here I cannot find a stable way to re-register nor remove red X for expired Avast 18.
Clean reinstall seems to be a only stable option, while Avast cannot get new license it works (i.e. no red X) without license except for short period of time after boot.
I have not attempted to re-install v18.5 (yet).
