Adaware has no affiliation with "registry mechanic" that I know of. That was probably just a pop up ad that came up coincidentally. The Registry Mechanic is also highly regarded, but helps diagnose and repair the system Registry file, which holds many of the system settings. Most people won't need this program.
Adaware has a free version for non commercial use. I usually download it from
www.download.com. Search for "ADAWARE" and the link comes up to download it.
Adaware handles "Scumware" (aka SPYWARE or ADWARE):
By definition "Spyware" refers to files that are downloaded with an application frequently without the consent or knowledge of the user for the purpose of reporting information back to the application's creator or some third party. The idea behind "spyware" is that your surfing habits, computer habits and who knows what else, are sent over the Internet to be seen by someone else for marketing purposes or other less than ethical reasons. (including credit card #s etc) Riding piggy back with legitimate programs at times, "spyware" is difficult to locate, and works in the background.
"Adware" works like spyware in that it transmits information to another person, persons or group. With adware you are sent advertisements based on your surfing habits. Adware can come bundled with legitimate programs and services on the Net. Like spyware, both are difficult to locate and operate covertly. They tend to slow computers down and cause instability.
Unlike viruses, anti-virus programs cannot locate these intrusions. Since spyware and adware are not technically viruses, and they do operate in different manners, they go undetected by these applications. The same holds true for firewalls. They cannot stop this type of software either.
The MOST important protection is a good virus scanner, such as Symantec's Norton AntiVirus. It's also healthy to check
WINDOWS UPDATE every week to get any security patches that are made available. XP can be set to do this automatically.
Most of the lil critters (excluding the recent Blaster and Welchia) come in through email. There are about 200 new trojans and viri weekly, but only a few make the news every year. Nothing will truly protect you, but a weekly Adaware scan, weekly Windows Update, and weekly updates to your virus scanner will greatly help.
Some other options are a piece of equipment called a "router" which goes between your computer and the cable/dsl modem, and acts as a firewall; or a software based firewall, although less effective. There are programs to monitor what your computer is sending OUT as well, which alert you of anything out of the ordinary.
I'm sorry for such a long response.

PS: I believe the one Katman is referring to is W32.Sobig.F@mm. It's not too out of control, but spreads in the traditional way through email, sending itself out to anyone in your contact list, etc. The message will have a file attached and may say "see the attached file for details". This one self destructs itself shortly before 9/11/03.
