Spyware Killer Pro uses four tools to combat programs that record information about the websites you view, usually in order to target you with pop-up advertising windows.

Spyware Scan searches your hard disk for malicious programs and deletes them. It picked up several items on our test PC, which were mainly tracking cookies and other relatively innocuous items.

It will also scan for junk files but this should be used with care, as it simply picks up files that match its list of suspicious names.

The Startup options are more useful, allowing you to check the bit of the Registry that deals with programs loaded automatically when you start the computer. This means you can see if anything suspicious is being loaded, without delving into the Registry itself.

Spyware Monitor watches your PC's goings-on to make sure no changes are made to settings, such as your Internet Explorer home page, without your knowledge.

The Pop-up blocker didn't block all ads and is somewhat redundant in the face of modern browsers which tend to come with their own effective blockers.

Finally, Anonymous Surfing makes sure you can't be tracked online, but is an unnecessary measure for most users.

This suite works but doesn't do much that you can't already do using built-in bits of Windows and free software like Spybot Search & Destroy.
