13. Security threats Most of the security threats mentioned involve a piece of malicious software (or code) that is intended to run on your computer without you knowing about it. Malicious software may be hidden inside another file or program, or run silently in the background. Most malicious software is designed to replicate itself and infect other files or computers. But what exactly the malicious code does to your computer depends on what it is and how destructive it is.

18. Sources of infection If you kept your computer in a sealed room, never linked it to a network or the Internet, and never inserted a CD or floppy disk, you would remain safe. But that would make your computer practically useless. So practice safeguards instead. As well as being wary of information coming into your computer, be careful when visiting Web sites that request information from you. Also ensure that you’re on a genuine site before entering any personal data.
19. Microsoft Update: an essential security precaution The most basic security step is to make sure your computer software is up to date. Microsoft releases regular updates—you may hear them called “patches” in the news media—to combat new threats as they appear. It’s wise to check for and install updates regularly. Updates for the Microsoft Windows® operating system and for Office are found on the Microsoft Update site.
20. Antivirus software Your most important and essential defense against viruses is antivirus software. Install it, use it, and keep it up to date. Antivirus software is designed to detect known viruses. Because new viruses are always being written, it’s essential to keep your antivirus software up to date. When a new virus hits the world, the antivirus software manufacturers typically have an update available for download on their Web sites within hours.
25. E-mail security After you’ve decided you want to open or save an attached file, you can do so by right-clicking its icon in the Outlook Reading Pane. If you’re still concerned that the message is infected with a virus or contains other malicious code, and if the sender is a friend or colleague, you can always ask for confirmation before opening it. If the message does turn out to be viral, delete it without opening it. And then delete it from your Deleted Items folder.

41. How to Delete Your Hard Drive Are you selling, recycling, or donating your old computer? Do you need to get rid of all the junk the kids have put on the hard drive from playing on the Internet? Is there objectionable content on your hard drive? Do you want to permanently delete data and files on your hard drive, giving your computer a "fresh start"? Wondering how to delete your hard drive? I know, by now you are probably saying "enough of the questions already!" Formatting does not permanently delete files on your hard drive. All formatting actually does is delete the addresses of the files on your hard drive. This leaves data from a formatted hard drive easily being recovered using data recovery software. This software is readily available on the Internet. Believe it or not, some data recovery software is even free of charge! A lot of people don't realize that Windows keeps every picture, web site address, video clip, email, and chat room conversation is written to your hard drive. Windows keeps the web browser cache, temp files, and other data. This is a very real threat to your Internet security and privacy.
