Protect your computer
You can greatly reduce your risk of online identity theft by taking these four steps to protect your computer:
1. Use an Internet firewall.
2. Visit Microsoft Update to verify your settings and check for updates.
3. Subscribe to antivirus software and keep it current.
Create strong passwords
Strong passwords are at least 14 characters long and include a combination of letters (both upper and lower case), numbers, and symbols. They are easy for you to remember but difficult for others to guess.
4. Don’t share your passwords with friends.
5. Avoid using the same password everywhere. If someone steals it, all the information that password protects is at risk.
