I say do a quick scan just to see if you're getting anything here--just in case.

I looked through the dw_news posts at one point, and there was no mention of a high number of cookies (35 in 30 minutes on LJ, one time) or Adware because of anything--however, in the comments to one post, I believe someone actually mentioned the problem and never got a response about that. I don't know which post now, though.
