Some people don't have time to invest in learning a new OS. Here's a couple tricks to use instead. Although FireFox is a damned good web browser there is still one better yet. Safari is a web browser designed to be used on Mac's. Mac has been so kind as to design a free version of Safari to be used on Windows. Safari is 1.9 X faster than IE and 1.7 X faster than FireFox. Cruising the Internet using Safari. Spyware, adware, and malware believe that you are a Mac user and 99.9% of the time leave you alone. Therefore more speed and more safety. Safari has very little limitations but they are there. FireFox is a good backup for the rare times that Safari is lacking.

This second is a little more interesting. I got this from the Kim Komando radio show
Along with e-mail, Web sites are hackers' favorite ways to spread their attacks. Some sites hide infections in downloads. Others can snag computers that simply surf to the site.
A near foolproof way to protect yourself is to surf the Web with a spare computer. If you run into trouble, simply reformat the hard drive. Trouble is, most of us can't afford a spare PC as virus fodder.
So try Sandboxie. This free program provides a safe space, or sandbox, on your computer. It's like having that spare PC. Sandboxie impersonates your hard drive. Downloads and infections are saved in Sandboxie instead of true hard drive.
If you run into trouble, simply empty Sandboxie. Infections and new downloads will disappear. Your Internet activity will disappear as well.
You can use Sandboxie for more than safe Web browsing. For example, you can run your e-mail program through Sandboxie. If you download a malicious attachment, empty Sandboxie and start over.
To run a program through Sandboxie, first open Sandboxie. Select Run Sandboxed>>From Start Menu. Then select the program you want. Start your Web browser this way to protect yourself on the Internet.
Sandboxie won't work for all situations. For example, you don't want your word processing documents to disappear. To ensure you're saving to the actual hard drive, simply start programs as you would without Sandboxie.
Sandboxie works with Windows 2000, XP and Vista.
Cost: Free
