How to Disable My Computer So No One Can Log Onto It But Me

Your private data might be compromised if the necessary precautions are not applied.

Computers hold private data. Users want to keep their information hidden from the public eye. Corrupted technical people, however, can use advanced devices to invade a password-protected network and even overwrite the login screen that exists in most Windows machines. Computer owners, with some basic software knowledge and a security device, can overcome those obstacles and sleep peacefully at night, knowing that their secrets are safe with them.

Things You'll Need

• Cable lock
• Compact discs
• BIOS password
• Mozilla Firefox
• Firewall
• Router

Instructions

1. Get a cable lock. A Targus or Kensington cable lock shackles your computer in one location. Be sure to check the compatibility of the connectors to your machine before your purchase.

2. Save your documents and other confidential data on compact discs. Then keep the discs in several safe locations. Thieves will find it more difficult to search for your information rather than looking for it in the most obvious location: the hard drive. Another benefit: If your system fails, you have backups.

3. Create an administrator BIOS password and a separate boot one that combine letters, numbers and special characters. Record both passwords on a piece of paper and store them out of sight. For most computers, pressing F2 or F12 will give user access to the BIOS system.

4. Install Mozilla Firefox for Internet security. You decrease your chances of getting a virus or trojan by using this alternative browser as it gives you immediate warnings of possible detections.

5. Use a software firewall. This application will prevent network sniffers from touching your computer's ports and other online privacy features.

6. Activate your router's firewall as well. Applying this extra precaution with a reputable and quality antivirus/antispyware suite will guarantee you the type of security you desire.

Tips & Warnings

• If your computer is a laptop, carry it in a backpack rather than a regular notebook case.

• Send your confidential emails with encryption.

• If possible, configure your computer to go to the login page after exiting standby or hibernate mode.

• Do not leave your computer in a public place.

• Avoid connecting to wireless networks that are not protected by a password, unless they belong to reputable sources.
