Setting Up Your Computer

So you got a new computer and you want to know how to keep it safe. How do you protect against spyware, adware, viruses, trojans, phishing sites, worms, and all those other diabolical programs? First, if you're not sure what these threats are, go to these PC Security, Spyware and Viruses pages to learn more. What's important to understand is that these programs can affect you in any of the following ways:

  • Exposing your personal information to people who shouldn't see it (whether a thief or your little brother).
  • Slowing down or crashing your computer.
  • Installing software that causes your computer to do things without your knowledge, like joining a zombie network and sending out spam.
  • Installing spyware that keeps track of everything you type and everywhere you browse on the Internet, and then sending the information off to someone else.

Whether it's a phishing site that steals your credit card number or a virus that crashes your computer, these threats are real, and you can help protect your computer from them.

But That's Not Going To Happen To My Computer

Probably every person who ever had a problem hit their computer thought it wouldn't happen to them. That's why it's important to set up your computer security from the start.

Ok, but where do these threat come from?
  • Web sites - Visiting the wrong Web site can change your Web browser settings or secretly install programs on your computer.
  • Pop-up ads - Clicking the close button in some pop-up ads can open new ads or cause programs to download
  • Instant messaging file transfers - Hackers have even invaded the IM world. This means that you can't always trust files that are sent in IM messages.
  • E-mail attachments - Even when it looks like a friend is sending you an attachment, the e-mail could be from someone impersonating your friend.
Is it hard to set up this security?

Not at all. Follow these four steps:

  • Make sure you have a firewall installed and switched-on. Most new computers come with a built-in firewall to ensure that outsiders can't get into it. Double-check that the firewall is enabled and then use it. If you don't have a firewall as part of your operating system, many antivirus products include firewalls.
  • Take advantage of automatic security and software updates. Typically, new computers include an automatic update feature, so make sure it's enabled and that you use it. Run an update the first time you use your computer on the Internet, and then update regularly afterwards.
  • Install and use antivirus software. A trial version is often included with your computer. If not, buy and install a reputable program before you go online. If you install trial versions of antivirus software, mark on your calendar when they will expire and be ready to re-subscribe before that date.
  • Install anti-spyware software. Spyware tracks what you do on your computer, and tries to sell you things through annoying pop-up ads that slow your computer down. Anti-spyware software helps ensure spyware doesn't have the chance. As with antivirus software, make sure that you keep it up-to-date.
Is that everything?

Well, those are your first defenses against online threats. Keep this stuff in mind too:

  • Download only from trusted sites, and consider paying for software instead of downloading the "free" version, which may contain spyware.
  • Check your browser settings to make sure your pop-up blocker and your phishing filter are set.
  • Read the fine print when you see an "I Agree" button. This is what software companies call the EULA or End User License Agreement.
  • Use common sense when opening file attachments. Make sure they are part of a legitimate e-mail message from someone you know. Even if the attachments look legitimate, sure your antivirus software is set to scan the attachment before it is opened. Also, use your e-mail spam filter to keep unwanted e-mails to a minimum.
  • Create and use passwords that are hard to guess on everything with sensitive information. It's best to use passwords that don't contain understandable words and have a mixture of letters, numbers, and upper and lower case - such as A8lp0Cu3N. And don't tell your password to anyone. Some things are better kept to yourself.

Of course the best defense against any online threat is your own common sense. As with non-computer life, it's your best bet for staying safe. Any time you stop to think before entering your credit card number or downloading files, you're being that much safer.
