Redirect Ads showing up

Is anyone else getting these redirects when logging into or navigating the website? Sometimes I click on the Show Posts or login link or some other link and I get redirected to some ads page.

Yes, I get them a lot. Sometimes they open a new window and I can just close it. Other times they take over the existing window and become more of a problem to close.
All seem to come from or something similar.

Huh, I thought this was fixed months ago (and I haven't seen them since then)... Though I did have to clear cache after the fix to get rid of them.
