Lavasoft Ad-Aware is one of the pioneering companies for the removal of adware, spyware and malware. The free version of Ad-Aware allows for updates to the latest definitions and program updates. Ad-Aware is also a very easy program to use, simply install and tell it to scan. When it is finished, you can either choose what to remove or have the program remove all of the detected infections.

Don't confuse Ad-Aware with an Anti-Virus software. The difference between the free and pay versions is simply real-time monitoring. The free version requires a manual scan of the computer where the pay version automatically detects and prevents problems.
