Choosing an antivirus program The cost of this software is very small compared to cost of the time you can lose fixing your computer or redoing lost work. If your computer did not come with a virus protection program, you can buy the software either in a retail box with an installation disc or as a software download from a website. Or, you may be able to get it free or at a low cost from your Internet provider. Once you’ve installed it, you will receive free updates to the software for a set subscription period, usually a year. This subscription is a very important part of your protection. Just as Microsoft releases patches and updates on a regular Getting StartED with Windows 7 322 basis through Windows Update, your virus protection program checks for regular updates from the virus protection program service. Like Windows Update, most virus protection programs allow you to schedule these updates so that they download and install automatically in the background, without any action required on your part. Getting security software for free or cheap Many companies offer antivirus software separately or in security suites that include a firewall, antivirus software, and antispyware. You can purchase and download this software directly over the Web, through Microsoft’s referral site, or in a retail box from a store. However, you may be able to get this software for free or inexpensively. Make no mistake about this—you do need this software, and it is well worth it even if you have to pay for it. ExplainED Free or cheap still means a legal, licensed copy of the software. Borrowing, copying, or loaning software without a license for each installed copy is illegal. Tips for getting security software Here are some tips for obtaining security software:  Look for free versions already on your computer. Check your computer for free or trial versions provided by your computer manufacturer. Check the Programs menu, your desktop icons, or any extra program disks that came with your computer for antivirus, virus protection, or security suite programs. You may be eligible for a free 30-day to one- year subscription.  Get free software from your Internet service provider. Check with your Internet service provider or your broadband provider—many offer free security software with their service, which you can install on all your computers in your household.  Get free software through your work. Some companies buy a site license, which allows employees to install a copy of the software on their computer at home. If you use a computer at home for your work, your company may pay for the cost of security software even if they don’t have a site license. 323 Chapter 9: Safeguarding Your Computer  Purchase a family pack. Every computer in your home should have security software. Many security software companies offer a discount when you buy several copies at the same time. These “family packs” usually include three to five licenses so that you can install it on all of your computers. Most antivirus programs or security suites are available for multiple versions of Windows so that you can install it on your Windows 7 computer, as well as older versions of Windows such as Windows Vista or Windows XP.  Don’t overbuy. You need only one firewall and one antivirus program on each computer. If you run more than one of each of these, they will not work together, and you’ll have to uninstall or disable one. Microsoft already provides a good firewall, automatic updates, and antispyware program free with Windows. You really only need to purchase and install an antivirus program—if there aren’t any free ones available on your computer, from your Internet service provider, or from your employer. Getting antivirus software through Action Center If you do not have antivirus protection, Windows Action Center can help you locate third-party security suites, antivirus, and spyware protection. Action Center provides links to pages where you can purchase, download, and install this software without leaving your desk. Before you install any virus protection or security suite program, make sure you will be able to leave your computer on for several hours after installation. Typically, these programs prompt you to run a full virus scan when installation is complete. Some programs even run a scan before installation to make sure there aren’t viruses already on your computer that could block or interfere with your virus protection software installation. A full virus scan can take several hours, but it is really important that you run this as soon as possible. After the first full virus scan, you usually have an option to schedule quick scans daily or weekly. Even with frequent quick scans, it is a good idea to run a full scan once in awhile. Many people find it convenient to run the full scan overnight while they are asleep. 1. Right-click the notification icon in the taskbar, and then click Open Action Center. If you do not have a virus protection program installed, Action Center provides a link to obtain a program online, as shown in Figure 9-25. Getting StartED with Windows 7 324 Figure 9-25.

During installation, you may need to allow the program to shut down other programs that might interfere with the installation. If you already have another virus protection or security suite installed on your computer, you may be prompted to uninstall it. After you download and install the antivirus or security suite program, you will be prompted to run a full virus scan. Getting StartED with Windows 7 326 Using the Security Center from a third-party Internet security suites You don’t have to use Microsoft’s Action Center or security programs.
