Hello,
I’m running Avast Internet Security 7. Since a month, when I haven’t used my computer for some hours like during the night or while I’m at work (the computer is usually always on), I get the message that my license has expired, or sometimes that my free trial is about to expire in 0 days, and all protections are switched off. If I check the license status at this point, it says that the license expires in 2013-07-13 and is valid for 0 days. The first time this happened my license was valid til september this year, but I bought a new one anyway, so now it really is valid until 2013-07-13.
Usually all I have to do is clicking the “fix this issue”-button (or whatever it might say in english) and all protections are switched back on and the license status starts behaving correctly (as for today it now says I have 333 days left).
This happens maybe once in a week. Now it happened two days in a row. Highly annoying. What to do? I have googled a lot and found what sounded like similar problems, but the answer usually is to uninstall Avast using the removal tool in fail-safe mode and install back on, and that doesn’t help…
I have also performed a startup scan as well as online scannings with different anti-malware tools and found nothing. I had however a virus earlier this summer, which was removed by a startup scan, but from what I can remember these no-protection-license-not-valid-problems started first a while after that.
