To protect the files you have to :

1. Use anti adware and spyware programs. Examples: Spybot, Search & destroy, Pest Patrol, and Lavasoft’s Adware.
2. Keep windows as well as Internet explorer up-to-date by applying the latest security patches.
3. Maintain the security level of the Internet Explorer at medium. Users must not lower the security level.
4. Use firewalls and web proxies to block access to web sites known to carry spyware.
5. Install layered protection.
6. Update the antivirus program. An up-to-date program will stop spyware as well as Trojans.
7. Install a startup monitor to protect your system.
8. Never accept “free” as being free---check out free software and downloads, there will be a hidden surprise or catch.
9. Never download software from warez sites. Pirated software is always distributed along with adware and spyware.
10. Use Spy checker to determine if the download has spyware. This can be accessed from the free computer securities pages.

An anti-spyware coalition has been instituted by Microsoft, Earthlink, McAfee, and Hewlett-Packard. The sellers are working towards anti-spyware legislation and putting protection systems in place. A survey shows that 87% of users know what spyware is and of this 40 percent through firsthand experience. Protect yourself and your work; keep your system free of adware and spyware.
