We’ve been served a “programmatic” ad with malicious software. We’ve shut down all such ads until we can identify and eliminate the culprit. It does NOT put software onto your hard drive, but it will lock your browser. If so, DO NOT CALL THAT NUMBER! Close and reopen your browser. [Note: Although this is not strictly related to the issue we identified with your help, I recommend downloading and then running the free app formerly known as AdWare Medic on a regular basis.] You can now use TTAG in completely safety. We apologize for the inconvenience.
