Follow these tips to protect yourself from identity theft when using the Web this holiday season. By Kimberly Lankford, Contributing Editor November 26, 2007 I'm about to start spending a lot of time on the computer, doing most of my Christmas shopping online this year. What do I need to do to protect myself from identity theft?The Monday after Thanksgiving is called "Cyber Monday" because so many people return to their offices after the long weekend and use their computers to start shopping for the holidays. And because so much money is changing hands online, it's also where many scam artists are going to reel in new victims. The crooks continue to get more creative. Most people now know not to respond to random e-mails asking them to send money to Nigeria or open strange attachments that could expose their computer to a virus. But the next generation of phishing scams may not be so obvious. Protect your identity. Even if a site looks legitimate, always type in the name of the Web site yourself rather than clicking on a link from an e-mail, which could lead you to a fake version of the site. And be careful of pop-ups from legitimate sites, too, which could send personal information to ID thieves.

And remember that legitimate businesses don't send e-mails asking a customer to update personal information -- no matter how real the message may seem. Watch out for "free" downloads, such as e-card sites and screensavers, which may include hidden spyware and adware programs that can monitor keystrokes, track Internet logins and transmit confidential information, warns Shane Keats, research analyst at the computer-security firm McAfee. Scam artists are also sending Christmas cards that load malicious software onto your computer when you click on the attachment. Know the source before opening online cards.

"They're creating pixel for pixel replicas of real Web sites, but they're made-up charities that sound official," Keats says. Not only do you end up giving money to a fake charity, but also you may be giving your credit-card and personal information to a criminal gang in a foreign country. "You've given them the first building block to your complete identity," Keats says. Before you give to any charity online, check it out at the Better Business Bureau's Wise Giving Alliance, and type the name of the charity in yourself in a new browser. Protect your computer. Because scam artists keep improving their pitches, it's important to protect your computer even if you're very careful. Install anti-virus software and a firewall, and update them regularly.

Several companies also offer programs that help assess the security of Web sites. McAfee's SiteAdvisor, for example, tests millions of sites and gives them a green, yellow or red safety rating. A site gets a red light if the test computers ended up with viruses, adware, spyware or unwanted programs after downloading from the site. Sites are also checked to determine whether they attempt to gain your personal information fraudulently, whether they have excessive pop-ups and whether their e-mail registrations lead to unwanted spam.
