That's odd. Avast gives me a warning on occassion, but otherwise says it's OK--if I use Firefox. Maybe one of the site admins should check with the Avast guys as to why Avast does this? IMHO it's not really a problem, and Avast actually works better than Norton on my system.
But if I use IE8 (Sometimes have to at Internet cafes or other locations), it absolutely refuses to open the Henshinjustice main page, forums--the works. Avast doesn't even factor into it--Internet Explorer just says "No, this is a dangerous page, you can't open it".
This happens even when I'm on my home PC using IE8.
But Firefox lets me in fine.
I don't think it's the virus scanner. It's probably NOT malware, but...
