Every time that I try to do a virus scan or update avast! (which I downloaded about a month ago, and have only done the beginning scan of my computer), I get a message that says "the license key for this product has been temporarily disabled
you system time/date have changed (which they haven’t); fix it and enter the license key again.
I don’t know what to do, because the time and date are correct on my computer. what do you suggest?
