What a nasty bug?

[b]Avast Antivirus: Running Smart Scan [/b] >> https://www.avast.com/faq.php?article=AVKB159

Smart Scan is an all-in-one scan that detects malware, out-of-date software, browser add-ons with poor reputations, network threats, performance issues, [b]and passwords that are weak, duplicated, or compromised.[/b]

I guess what you see is related to avast password check ....

I beleave that such behaviour of the AV compromises it. What should I think about when I see that?
