I've been using Avast for quite a awhile and today for the first time whenever I do anything on your site I get this warning:
pxl.ibpxl.com is currently listed as suspicious and may be dangerous. Use with extreme caution.
I also left a message with Avast to check into it as well. I'm not sure if this pxl.ibpxl.com is something normal for your forum and for some reason, maybe an update, is now trying to block it, or if this is a redirect thing going on that your forum doesn't know about?
Anyway let me know so I can take action to stop it from dinging me each time I try to do something in this forum.
