We apologize for the ongoing perpetuation of unauthorized advertisements, such as drivecleaner.com, systemdoctor.com, or errorsafe.com in our network. We would like to notify you that in order to achieve a thorough and lasting resolution to this issue we have tightened restrictions around the submission of ad copy, begun scanning all advertisements for potential abuse, and forged partnerships with established anti-spyware and internet security companies to ensure detection and removal of these ads. Locating offending advertisers unfortunately continues to pose several difficulties. To that extent, if you are still experiencing problems with any advertisements that you believe to be abusing our network, we would appreciate any information you could provide about these ads.
