Somehow the "mouse over" links have returned. If you see a green highlighted word or phrase it is a link. If you mouse over it it pops up a description. These are ads or something which I did not put here, they are spam! I haven't figured out how to get rid of them yet.
DON'T CLICK ANY OF THE LINKS!!
I had the same issue a few weeks ago. As it turned out my issue was a "plug-in" into my browser causing the "problem". I just removed the plug-in and the issue disappeared. I've not seen any since.
Now I don't see them on my work pc. I'll try on the laptop later.
Stop surfing those tool sites in the red light district. Your 'puter will catch sumpthin and brig it home ;P
Didn't it turn out to be a add-on tool bar?
Havent seen any, but I will let you know if I do.
