What is “application/gas-events-abn” object in Wor

Question

I'm using Wordpress to create a blog and I noticed that when I save a post multiple times, a weird element appears in the code, creating a big white space in the bottom of the post.

The code looks like this:

...post content

 

<object id="ba7ab859-2a8a-9fa1-988a-4a9938aba59b" width="0" height="0" type="application/gas-events-abn"></object>

Every time I edit a post I have to remove it. With Joomla sometimes used to happen the same thing. What can I do to solve this?

Answer 1

Your site (or browser) has been hacked. You can find the same string with varying id in some forums:

• social.msdn.microsoft.com
• social.technet.microsoft.com
• answers.atlassian.com
• forum.dancehallreggae.com
• many more.
