Is your computer time and date correct?
Are you logged as an administrator? How many admin accounts do you have in your computer?

How many admin accounts do you have in your computer?

Just curious Tech, what does that have to do with anything?

I mean, in more than one admin accounts environment, avast could behave strange on registration.

Huh. That’s weird. Thanks for the info!
