Computer users may be surprised to discover unwanted pornographic materials on their hard drive thanks to porn dialers like the CABDialer malware. The CABDialer hijacks the computer modem and changes its settings, allowing the modem to make unscheduled calls to expensive adult-content telephone numbers. Through these connections, the computer downloads illicit content and makes changes to the internet browser.

The source of these problems can be determined and eliminated from computers thanks to the advent of good anti-spyware technologies like those developed by the ZookaWare company. Blue Penguin has created a system known as SpyZooka, which is able to provide guaranteed service in detecting and removing porn dialers like CABDialer – and other malware – from computers with tremendous success.
