PC Magazine Fighting Spyware, Viruses, and Malware (0764577697) cover image
Think there's no malicious software on your computer? PC Magazine thinks you should think again.

Scans by ISPs have revealed as many as twenty-eight spyware programs running on the average home computer--like yours. That's a lot of people prying into what's on your PC, and a DSL or cable connection is a virtual welcome mat. But by following Ed Tittel's advice, you can learn how invasions occur, spot an infestation, repair damage that's already done, and slam the door on those who want to hijack your PC--along with your wallet.

Here's how you can
* Learn to recognize when a Trojan horse, a virus, adware, or spyware has invaded your PC
* Get the tools that can cure an infection
* Dig into the Windows Registry to remove the nastiest of bugs
* Prevent a recurrence with personal firewalls and protective software
* Deal with the onslaught of spam
* Keep your defenses up-to-date


Give it the boot

If you believe you've caught something and you're willing to kiss everything goodbye that you've added to or changed ... since the last time you booted up your computer ... try this. While Windows is first booting up, hit the F8 key .... Choose the Last Known Good Configuration option, and Windows should boot running the version of the Registry that existed the last time your system booted--that is, before you got infected.

Online Content

In my book PC Magazine Fighting Spyware, Viruses, and Malware, you have no way to link directly to online content, nor can I take you there in any kind of meaningful way. Here, however, you need only follow my links -- which I maintain and update on a quarterly basis -- to jump directly from mention of any item to the item itself. In this online information, I follow the same layout and structure as in Appendix B of my book, which provides pointers to everything mentioned in the book that's available online. I hope you'll find this useful, and ask for your input and feedback, as well as your suggestions for items that should be added to this list (as well as items that should be removed, as long as you can give me a reason why this is a good idea). To that end, send me your comments, questions, suggestions and so forth via e-mail at etittel@lanw.com.

Can't Find Something?

If you find yourself clicking a link that doesn't take you where you think it should, or just plain doesn't work, there are a few things you can do about it. First, please e-mail me using the email address I gave earlier to let me know what's not working. Second, try visiting the root URL for the site to see if it's working (in other words, if something at Microsoft.com isn't available, try going to the home page at http://www.microsoft.com/ to see if it's available). If that works, and there's a search engine on the site, try using it to get as specific as you can to find what you seek. If that doesn't work, try a general search engine like Ask.com, Google, or Yahoo! and see if you can do any better. Ultimately, if you let me know what's going on, I'll figure things out and fix or replace them, but these strategies should serve you well in the meantime if you try them for yourself.
