If you are new to the Web and the Internet, this book suggests how you can protect yourself against the various types of malware lurking out there in the Net. Like beware of downloading attachments from unknown senders. These might be viruses that could ruin your machine. It is recommended that you install an antivirus program, that can keep an eye out for the latest viruses.
And be careful of the numerous phishing emails that purport to be from eBay, Paypal or your bank, urging you to login to your account. The book gives no effective technical means to detect phishing. Instead, you are urged to manually exercise caution when getting one of those messages. This advice is typical of what is currently considered standard wisdom in antiphishing. Few, including the book's author, appear to have conceived of a simple antidote.
