My license expired in May 12 2012, why i want to upgrade to version 5 while the license end in 2012? Until 2012 i don't need to upgrade or buy any antivirus software, version 4.8 upgrade virus database each time until May 12 2012. Why must the company ending old version just because new version come out? My license end in May 12 2012? All i see of these is capitalism, forcing people to upgrade/buy your product.
I admit Avast is most reliable antivirus compared to other antivirus software but this kind of advertisement tactic is unwise making user like me annoyed, it is like forcing to upgrade or buy your product. The pop up disturb works, when i was playing games suddenly it come out and ruin it. The pop up is from the software, now it act like virus/malware it self...don't you see?

Thanks to H.Seldon, it work, now there is no pop up anymore.
The point is, it is my right when or if i want to upgrade it or buy new one, no need for the company keep annoying me with that kind of pop up. No matter if new version is better or whatever, it is up to me.
