Internet security suites combine several of the most important types of security software -- including antivirus, antispam, anti-spyware and firewall program -- into one unified package. But choosing a security suite is only one component of a good online safety plan. Experts recommend keeping these factors in mind when selecting and using security software:

  • Consider supplementing with extra anti-spyware software. See the ConsumerSearch reports on anti-spyware and antivirus software for recommendations, including some free options.
  • Experts recommend using a router with an integrated firewall as the first layer of protection, and a software firewall as the second. Hardware firewalls are more effective than software ones, experts say, and many routers include one.
  • Though you have security software installed, you must still monitor your Internet behavior. Be careful before clicking on an ad or a download link, and don't open e-mails or attachments that look suspicious. The mainstream media now has good coverage of the latest Internet dangers.
  • Disable file- and printer-sharing options if you aren't using these features. Remote file sharing is a common vulnerability that hackers use to access the contents of a hard drive.
  • When choosing Internet security software, be sure to check system requirements. Pick the correct version for your operating system. All Internet security suites are compatible with Windows XP and Vista, except as noted in this report.
  • Consider using Firefox or Opera web browsers for most Internet surfing. Experts agree that these browsers offer more security than Internet Explorer, even though Internet Explorer 7, the current version, has better security features than previous versions. See the ConsumerSearch report on web browsers for more information.
  • Update Internet security software regularly. Be sure your software is set to check automatically for updates. Antivirus software needs to be kept up-to-date with frequently downloaded virus definitions, and patches are issued often for security software.
  • Scan e-mail attachments before opening them, and scan outgoing mail. Although it may slightly slow the sending and receiving of mail, the biggest virus threats still come via e-mail. Scanning outgoing mail is additional insurance that you aren't sending along infected mail. Most programs can be set to do this automatically.
  • Allow automatic Windows updates or frequently check the Microsoft website for security updates and patches to the Windows operating system. It doesn't take long for hackers to exploit vulnerabilities in Windows operating systems, and keeping your system up-to-date is the best foil.
  • Look for software with a multi-PC license if you have more than one computer to protect. Many Internet security suites are offered in versions that allow them to be installed on more than one computer, typically three. If you only need protection for one computer, however, less expensive versions that can be installed only on a single machine are usually available.

Many security suites have some antisocial behaviors. They are unwilling to share your computer with other security programs, and in some cases, they interfere with unrelated harmless programs. Since experts recommend using several anti-spyware programs, those who want full protection have a dilemma. Spy Sweeper and Spyware Doctor are highly regarded by reviewers. If you are already running one of those programs, your best bet is to consider a suite that won't conflict. User reviews are the best guide.
