Avast warning: This site could have harmed your computer.

I have tried to access my Twitter and Tweetdeck this morning and it keeps popping up a message saying “This site could have harmed your computer.” without any option to close the pop-up or resolve it. How can this be fixed?

I’m having exactly the same problem. Only happening with firefox, can use other browser. I’ve tried setting twitter as an exception, but still keeps popping up.

I’ve tried setting them as exceptions as well but no luck, and it’s happening with Chrome for me.

It’s a false positive.

Avast is working on it now.
