Does anyone use the 'whos.amung.us' tool? Help

Hello everyone!

If you are not familiar to the 'whos.amung.us' tool, it tracks in real time how many users are on your website. Anyways, I have been using this for MONTHS. Now all of the sudden, I have received several e-mails from AVG Anti-Virus users saying AVG picked up a threat coming from this tool. I have removed this tool, and since then, there have been no virus threats. Has anyone else been experiencing this?

If anyone has AVG (I use avast), can you check out my second site…
