Still fine with my Norton, and also works fine with the school ESET Antivirus. I think the reported 'dodgy image' was a false alarm. Remember, AVG is saying it is a 'Phishing' site, and it's difficult to understand how an Image Hosting site can be classed as Phishing.
phishing /ˈfɪʃɪŋ/ noun the fraudulent practice of sending emails or other messages purporting to be from reputable companies in order to induce individuals to reveal personal information, such as passwords and credit card numbers.
