Now, if you take the proper precautions, your exposure to viruses will be minimal, if not nil, and you will have very little need for the auto-protect feature of your antivirus software. Naturally, whether you disable your antivirus software’s auto-protect feature is up to you, but if you keep the following practices in mind, you should be able to effectively eliminate your computer’s susceptibility to viruses.
If you don’t download any documents or applications from the Internet, if you’re not connected to a local network, if you have a firewalled connection to the Internet, and the only type of software you install is off-the-shelf commercial products, your odds of getting a virus are pretty much zero.
Viruses can only reside in certain types of files, including application (.exe and .scr) files, document files made in applications that use macros (such as Microsoft Word), Windows script files (.vbs), and some types of application support files (.dll, .vbx, .vxd, etc.). And because ZIP files (described in Chapter 2) can contain any of the aforementioned files, they’re also susceptible.
