Thanks, that's pretty helpful. I'm glad that there are some free programs out there . . . It helps that I've gotten to be quite the safe surfer in my time. When I first came to college, I didn't even know that spyware existed, and I didn't realize how easy it was for your computer to get a virus. I had some problems my first two years, but my former boyfriend (a complete computer wizard) straightened me out. So it looks like a free program will work for me. Thanks!
