Just installed latest version (11.1.2245) of Avast Free Antivirus. Previous versions required registration. Now after installation, I see that registration complete, but I did nothing.
Is it for 30 days or 365?
That doesn’t make sense at all. Avast will never automatically register you. Try a repair of avast via add/remove and at the end it will ask you to restart your computer and follow the instructions. Answer these questions.
What Windows OS you have? Service Pack?
What antivirus did you have prior to using avast? Did you use it’s uninstaller utility after uninstalling your previous antivirus?
What other antispyware you have? E.g. Windows Defender, Malwarebytes Antimalware, SuperAntiSpyware?
Check your computer date and time and make sure it’s correct.
If repair doesn’t work. Follow these instructions.
Make sure your computer has the latest updates from Microsoft Update and the latest service pack of your Windows OS?
