Tips that can help you keep your computer – and the personal information it stores – safe.

Virus protection software should be updated regularly, and patches for your operating system and other software programs should be installed to protect against intrusions and infections that can lead to the compromise of your computer files or passwords. Most Internet Service Providers will allow you to download antivirus and privacy protection software for free. Check your service provider’s website for details.

Do not open files sent to you by strangers, or click on hyperlinks or download programs from people you don't know. Be careful about using file-sharing programs. Opening a file could expose your system to a computer virus or a program known as "spyware," which could capture your passwords or any other information as you type it into your keyboard.

Use a firewall program, especially if you use a high-speed Internet connection like cable, DSL or T-1 that leaves your computer connected to the Internet 24 hours a day. The firewall program will allow you to stop uninvited access to your computer. Without it, hackers can take over your computer, access the personal information stored on it, or use it to commit other crimes.

Use a secure browser – software that encrypts or scrambles information you send over the Internet – to guard your online transactions. Be sure your browser has the most up-to-date encryption capabilities by using the latest version available from the manufacturer. You also can download some browsers for free over the Internet. When submitting information, look for the "lock" icon on the browser's status bar to be sure your information is secure during transmission.

Before you dispose of a computer, destroy all the personal information it stored. Deleting files using the keyboard or mouse commands or reformatting your hard drive may not be enough because the files may stay on the computer's hard drive, where they may be retrieved easily. Use a "wipe" utility program to overwrite the entire hard drive.

Look for website privacy policies. They should answer questions about maintaining accuracy, access, security, and control of personal information collected by the site, how the information will be used, and whether it will be provided to third parties. If you don't see a privacy policy or if you can't understand it consider doing business elsewhere.
