I was on this site...
RangerRequirements looking for a picture for the "find a pix again" and I right clicked, then left clicked ( a feature in Avant, to go back a page) and I got a "please do not attempt or your browser will lock up " warning. Well being a knucklehead I had to try it a couple of times, and it sure did lock it up. Now there were no images on the site, so whats the point of disabling right click, and then being malicious on top of that.
