I hope you are right. But not Avast, but Windows (7) is warning me that I should update Avast! In the windows problem center it says that the virusdefinitions are too old. Avast says it is from August 13, so I understand why Winodws says the definitions are too old... So something seems to be wrong. Either in Avast or in Windows not picking up that Avast is updated. So what's the culprit?
