When did this start?
Any link I put in a gmail email is now re-written to point to google.com with a redirect out to the site I linked afterwards. I don't use gmail often but I just linked something to a friend and was surprised to see google redirect it through themselves first. Upon closer inspection ALL links are rewritten to point at google.com and are redirected afterwards.
Not sure I like this one bit. Is this a virus or intended behavior? My comp did not detect a virus but it's what a virus would do...
