This free utility scans your PC to identify and remove any adware or spyware components.

For the uninitiated, adware or spyware is unwanted software that can be installed on your PC, either with other software or when you visit websites (cookies etc).

They can track your surfing habits, push aggressive advertising at you, and generally abuse your privacy.

This new version completely overhauls the scanning engine, which results in more accurate scanning methods and an all-new program architecture. This new version now supports the detection of embedded malware, including known and emerging threats.

The new TrackSweep module will control privacy by erasing tracks left behind while surfing the web through Internet Explorer, Firefox, and Opera, with one easy click.

You decide exactly what is scanned on your PC, from a single folder to the complete system. Files larger than a specified size can be skipped, making for a quicker scan. Flagged components can be quarantined, letting you restore them if their removal causes problems.

Note that the free version is for personal-use only. You can purchase the Pro version for only $39.95.
