3. Use anti-virus and anti-spyware software, as well as a firewall, and update them all regularly.
Dealing with anti-virus and firewall protection may sound about as exciting as flossing your teeth, but it's just as important as a preventive measure. Having intense dental treatment is never fun; neither is dealing with the effects of a preventable computer virus.
Anti-virus Software
Anti-virus software protects your computer from viruses that can destroy your data, slow your computer's performance, cause a crash, or even allow spammers to send email through your account. It works by scanning your computer and your incoming email for viruses, and then deleting them.
To be effective, your anti-virus software should update daily with antidotes to the latest "bugs" circulating through the Internet. Most commercial anti-virus software includes a feature to download updates automatically when you are on the Internet.
What to Look For and Where to Get It
You can download anti-virus software from the websites of software companies or buy it in retail stores. Look for anti-virus software that:
- Removes or quarantines viruses.
- Updates automatically.
Anti-spyware Software
Installed on your computer without your consent, spyware software monitors or controls your computer use. It may be used to send you pop-up ads, redirect your computer to websites, monitor your Internet surfing, or record your keystrokes, which, in turn, could lead to the theft of your personal information.
Clues that spyware is on a computer include:
- A barrage of pop-up ads
- A hijacked browser — that is, a browser that takes you to sites other than those you type into the address box
- A sudden or repeated change in your computer’s Internet home page
- New and unexpected toolbars
- Unexpected icons on the system tray at the bottom of your computer screen
- Keys that don’t work
- Random error messages
- Sluggish or downright slow performance when opening programs or saving files.
You can take steps to limit your vulnerability to spyware:
- Update your operating system and Web browser software. Your operating system (like Windows or Linux) may offer free software “patches” to close holes in the system that spyware could exploit. Make sure to set your browser security high enough to detect unauthorized downloads.
- Download free software only from sites you know and trust. It can be appealing to download free software like games, file-sharing programs, customized toolbars, or other programs that may change or customize the functioning of your computer. Be aware, however, that many free software applications bundle other software, including spyware.
Firewalls
Don't be put off by the word “firewall.” It's not necessary to fully understand how it works; it's enough to know what it does and why you need it. Firewalls help keep hackers from using your computer to send out your personal information without your permission. While anti-virus software scans incoming email and files, a firewall is like a guard, watching for outside attempts to access your system and blocking communications to and from sources you don't permit.
Some operating systems and hardware devices come with a built-in firewall that may be shipped in the "off" mode. Make sure you turn it on. For your firewall to be effective, it needs to be set up properly and updated regularly. Check your online "Help" feature for specific instructions.
If your operating system doesn't include a firewall, get a separate software firewall that runs in the background while you work, or install a hardware firewall — an external device that includes firewall software. Several free firewall software programs are available on the Internet.
Don't Become a Zombie Drone
Some spammers search the Internet for unprotected computers they can control and use anonymously to send unwanted spam emails. If you don't have up-to-date anti-virus protection and a firewall, spammers may try to install software that lets them route email through your computer, often to thousands of recipients, so that it appears to have come from your account. If this happens, you may receive an overwhelming number of complaints from recipients, and your email account could be shut down by your Internet Service Provider (ISP).
