I noticed that the iframe that LinksAlpha creates on your site contains this code:
which is a script that creates an invisible 1px x 1px iframe which loads a url from from a subdomain on the same domain:
pro-market.net is a known spam server.
To see this, right click in the widget area and select:
This Frame => Show only this frame
On the page that opens, right click and select:
Scroll down to where you see:
paste that url into your browser address bar.
Inspect the code:
document.write("<IFRAME WIDTH='1' HEIGHT='1' .......
I'd like to know how why this code is being snuck onto our web sites.
