Spyware Doctor removes and provides real-time protection against just about any threat you can think of including spyware, adware, trojan horses, keyloggers, browser hijackers, phishing attacks and other malware threats. For Internet Explorer users, it also provides a built-in popup blocker and malicious site guard.

Scanning is quick and covers many areas of your PC including Windows registry, file system, processes and tasks, browser, network configuration and cookies. Since the scan is pretty quick, the most effective way to use it is to install it for use on Windows startup to ensure that your system is clean before every use. However, this will make your boot-up time longer and can sometimes be frustrating as you wait for Spyware Doctor to report that there's nothing new to remove since yesterday anyway. You may also find that it conflicts with other anti-virus or anti-spyware programs and you may be prompted to remove them or find that they have been effectively disabled by Spyware Doctor.

It's also important to ensure that Spyware Doctor has constant access to the internet as it is updated daily with the latest threats. However, these threats can sometimes be exaggerated out of proportion such as in the case of keyloggers which Spyware Doctor may warn you is a high threat but in reality, is benign.
