Mobile malware is getting lots of attention these days, but you can’t forget about your PC’s security—after all, you probably still use it to pay bills, shop online, and store sensitive documents. You should fully protect yourself to lessen the chance of cybercriminals infiltrating your computer and your online accounts, capturing your personal information, invading your privacy, and stealing your money and identity.

You need to guard against viruses, of course, but not all antivirus programs catch all threats, and some do better than others. You have to watch out for many other types of threats, too: Malware invasions, hacking attacks, and cases of identify theft can originate from email, search engine results, websites, and social networks such as Facebook. They can also come in the form of links or advertisements for phishing and scam sites. But with some education on the topic, and the right tools, you can identify such scams and avoid falling victim to them.

Protecting your data from computer thieves and from people who tap in to your Wi-Fi signal is also important. Encrypting your computer is the only way to ensure that a thief cannot recover your files, passwords, and other data. And unless you password-protect and encrypt your wireless network, anyone nearby can connect to it, monitor your Internet usage, and possibly access your computers and files.
In this book, we cover the security threats you should watch for, and the tools you can use to protect against them.
