Just you, I think
I had something similar a few days back... from some guy's picture that was linked
from a site that required a username/password to reach. If you're getting it from one certain
thread, that could be it. If not, grab a program called "ad aware" off the net, and
scan your system for spyware. You probably picked up something, somewhere.
You can grab ad-aware
here
Edit... Wow. I was running version 5.0. 5.83 is now out.
Downloaded the latest, and it found/removed 9 new "bad cookies" I wasn't aware of,
along with an additional two registry entries made without my knowledge. Sweet!
You may find, as I have, that certain websites may require one or more cookies identified by ad-aware.
If that's the case, as in 3 on my machine... you can choose to exclude those from cleanup.
Just lettin ya know!
