If you're storing personal information such as SSNs, financial records, tax returns, birth dates, or bank account numbers in your computer, the following tips can help you keep your computer and your personal information safe from intruders:
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. 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 Aspyware, at 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.
Try not to store financial information on your laptop unless absolutely necessary. If you do, use a strong password B a combination of letters (upper and lower case), numbers and symbols. A good way to create a strong password is to think of a memorable phrase and use the first letter of each word as your password, converting some letters into numbers that resemble letters. For example, "I love Felix; he's a good cat," would become 1LFHA6C
Before you dispose of a computer, delete 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
