Doggos posted on PDW yesterday about the problem.

Avast hates us!
We are aware that Avast has been blocking functionality of the site under the guise of phishing and malware since yesterday.
We are working on getting them to resolve the problem, but in the meantime, we would recommend deleting or disabling Avast.
Please also flag the malware/phishing report as a false positive if you're an Avast user.
