Free ad aware software for windows

Ad-aware is a small detection and removal tool that will comprehensively scan your computer for known Datamining, aggressive advertising, Parasites, Scumware, Keyloggers, selected traditional Trojans, Dialers, Malware, Browser hijackers and tracking components.
Installation Note: Uninstall any previous version before installing this one, as to avoid problems.
You can BUY the PRO or PLUS version.

Ad-aware Cloak is used to allow Ad-aware to open completely when there are items on the system which use to close Ad-aware when it attempts to start, such as some of the CoolWebSearch variants.. If Ad-aware opens and you are able to scan, then this program is not necessary.
To use Ad-aware Cloak, save it to your system, and run the program before opening Ad-aware. Once Ad-aware Cloak opens, click "Activate Cloak" and then open Ad-aware and scan as normal. When you are done using Ad-aware, close Ad-aware Cloak.
Ad-Aware is completely free! A Plus version is available for immediate download for $26.95 or CD On Demand for $9.95 which features real-time monitoring and blocking for your system. Not only can you remove privacy threats from your computing environment, you can also BLOCK them from invading your system in the first place.

With many files (cookies for example) theres no easy way to view any information about them.
The HexDump extension for Ad-Aware will let you view a hexadecimal version of a file turned up in a scan,and also an "English" translation of the hex code.
This can provide you with additional information you may find handy such as the URL of the originator of a cookie.
Access the HexDump extension at the "Scanning Results" screen; right-click on a file and choose "Extensions | Show Hexdump".
HexDump works with all versions of Ad-Aware.
