Pop up ads that just wont go away?

[Mr.Chang]

Ok, I've got pretty good security, I go to clean sites, just mainly use my computer for music or blog or just plain random searches on familiar sites...But I have seem to acquired a virus that just simply wont go away, I have add blocker and everything and my spyware doesn't seem to pick it up...Heres a link of a picture i took of this annoying devil...

Now if there is anyone that can tell me how to get rid of this, you will literally be my hero cause this is getting extremely annoying and keeps popping up in EVERY site i go to, and seems to be followed by three more just like it, one that looks like a facebook I.M. and another that is flash videos and quiet rarely porn ads....Please help and hopefully the answer can help others with this problem
P.S (its the second blue link)
