Green links at homepage

I don't know if this goes here, but what's about these green links appearing at homepage and widgets? When i hover them, they are showing text about some survey "win an ipad", there's the same thing on this forum... What I mean is what's the cause for that to show up and how to remove it?

This forum doesn't have those links so it must be generating from malware on your computer. Run a good program to scan ans remove the malware.

Yep, it was just some extension in Chrome (greatsaver) making the problem... Deleted it, problem solved. Thank's.
