Tried in Google Chrome and Firefox, running AVG 2011 (free), Malwarebytes (paid), and Zonealarm (free) on 2 computers - a Vista laptop and Windows 7 desktop - can't get anything to come up. If there IS a problem, I would definitely rather it come up for me so I could see the message. It would definitely be helpful if someone could post the exact message so that if there is an issue with something on the site, we can pinpoint it.
I didn't design or work on the Eastmall site, but I have been a web developer since 1994, professionally since 2001, and I've personally had my own JavaScripting set AVG off before. Not intentionally, but because there was an error in my code, or because I wrote a chunk of code in a way that appeared to the antivirus to be a "signature" of something in the AVG database. These were false positives of course, but while my script was benign, I still had to find and correct the issue of course. Usually the contents of the message that popped up was the only way to diagnose the issue, especially when dealing with hundreds or thousands of lines of code.
