Windows XP the Safer Way
You may be surprised to learn Windows XP has a built-in feature that offers considerable protection from spyware, adware and such.Most operating systems make a distinction between Limited users, who run programs and work with documents, and Administrators, who change the way the computer works. Limited users can't make changes that affect the entire computer, only their own folders, desktop and settings.
It may sound inconvenient, but it's really a wonderful safety net. I've been an Administrator on many, many computers over the years, but still login as a Limited user 90% of the time. It protects me from making stupid mistakes. But these days the best part is it stops spyware, adware, and similar attacks dead.
