How to Watch for Identity Theft Using Google Alerts

Google Alerts is a great way to set up a virtual personal watchdog that will constantly look for attempts at identity theft. This is much better than checking these values by hand periodically, since Google Alerts lets you set it and forget it. You'll be notified as soon as a thief posts your data online for others to use.


Steps


  • Set up Google alerts for your key personal data. Here are some of the alerts you might consider running:
  • Your name
  • Your phone number
  • Your address (home and place of work)
  • Your date of birth (just to be safe)
  • Your license plate number
  • Your drivers license number
  • Your email address

  • Read the alerts that Google will email you when the information you listed becomes published anywhere on the web that Google crawls. If any of these alerts are sent to you in a way you think indicates a potential identity theft, take immediate action.
  • Check the link(s) provided in the Google alerts. Look for anything unusual either within the sites you're sent to, or look for a pattern in general relating to the type of sites you're being alerted to (such as financial institutions, sites that hold security information, etc.)
  • Be especially alert if the returns with your personal details suddenly spike. You might get an occasional ping with your personal details from Google Alerts but if you notice a sudden increase in the amount of returns reaching your in-box, this is a cause for concern and should be investigated quickly.

  • Seek help from a legal representative or the local police if you're not sure how to respond to an alert where identity theft appears to have occurred. You may need to respond quickly if it appears that fraud may be happening using your personal details. See the Related wikiHows below for further details on preventing and dealing with identity theft online.

Tips

Be careful about what warnings you set. Because your search history is saved, and Google alerts are sent to your email address, you can inadvertently expose information you want to keep private using these techniques if someone were to access your email. Some things to avoid using in these alerts:

  • Your social security number
  • Your credit card numbers
  • Your bank account numbers
  • Your mother's maiden name, since banks and some other institutions use this as an identity check.
Be aware of when you've put your own personal information out there on social networking sites, for domain addresses, etc. Try to be vigilant about checking privacy boxes to keep as much personal information as possible away from public eyes.

It is important to refine searches to help Google Alerts be the most efficient in returning the personal information. For example, you can enclose your name or address in quotation marks. You can also use plus and minus signs to narrow the returns to particular terms, names or information.

How to Update Your Computer's BIOS

A computer's Basic Input-Output System (BIOS) is embedded software on a motherboard that will control attached hardware. It provides an operating system with information about hardware, and is designed to support a specific range of components. The BIOS itself is typically an EEPROM, or Electronically Erasable Programmable Read-Only Memory, that is programmed with "firmware" and has the ability to save small amounts of information specific to user configurations. BIOS components are often soldered to the motherboard and therefore not serviceable by the user. Still some of these can be inserted into a socket, allowing its replacement.

All BIOS components are serviceable via a firmware upgrade that is known as "flashing" this process is called "updating the BIOS". The process itself is fragile since any power fluctuation during a flash may irrevocably corrupt a BIOS' firmware. Great care will need to be taken in order to safely accomplish this.

This guide will help you flash your BIOS by taking precautions and walking you through each step. Not all computers will have the same BIOS manufacturer, let alone the same process, but many have similar steps and precautions.

Steps

1. Determine your needs. Did someone help you update the BIOS last month? Maybe the BIOS has never been updated since you purchased your PC years ago. Will an updated version fix a problem you are experiencing? Answers to these questions will help determine if you need to verify version numbers and whether an update is necessary. Not all BIOS updates are necessary, but for the hardware enthusiast, obtaining the latest BIOS may equate to better performance.

2. Determine your system's origins. This is an important first step to determine where to locate and download the correct BIOS update version.

  •     For Desktops, did you purchase this computer as a bundled, pre-built system, or was it assembled from purchased components? The larger, more popular manufacturers and builders include companies such as Dell/Alienware, HP/Compaq, IBM, Lenovo, Sun, Gateway,Acer, etc. For these, visit the manufacturer's site. For a custom system built from purchased components, visit the motherboard manufacturer's website.
  •     For laptops, visit the laptop manufacturer's site, such as Dell/Alienware, HP/Compaq, Acer, Toshiba, etc.

3. Discover what update methods are available. Not all BIOS updates are performed in the same manner. The desktop or laptop system or motherboard manufacturer determined in the steps above provide support information about BIOS update methods they offer. Some motherboards can be updated by executing a program from the operating system level after booting from the hard disk. In other cases the system must be booted from a floppy disk; CD or USB thumb drive (using software supplied by the system or motherboard vendor). Some manufacturers will use their own custom application to update the BIOS, others will use a third party utility to update the BIOS while booted from the legacy DOS operating system. The latter may be split into two different files, or bundled together as a CD or floppy image with an extracting application. Download the appropriate updating software and BIOS from your manufacturer's website.

4. Backup your existing BIOS first! If using BIOS update software executed from Windows or another operating system, backup the existing BIOS image first. Some BIOS update software versions have this functionality built-in (e.g., "Save" or "Backup"), and will advise you to perform a backup first.

5. Perform the update. Run the downloaded installer or application executable for the BIOS updating software. If the software prompts you for a floppy, use a formatted 1.44MB 3.5" floppy disk. It doesn't matter if the floppy is blank or not because the data will be overwritten if you don't mind wiping the disk.

  •     If using a floppy, insert it into the drive and restart the system to boot from it. Some floppy images contain an "autoexec.bat" file to automatically run the BIOS update. Others will just have the update software, the updated BIOS image, and possibly a 'readme' text file containing directions. If there are no directions, but there are at least two files (ie: "A06_123.bin" and "awflash.exe"), follow this example: Enter a command such as "awflash A06_123.bin" and press enter. This will execute the update software and specify the A06_123.bin file to flash the BIOS.
  •     Compare the two versions. Most BIOS update software will read the existing BIOS image and determine its version, then compare this to the downloaded BIOS image. If the system's existing BIOS version is older, perform the update. The user interface of BIOS software may vary greatly, yet typically menu buttons or selections such as "Write", "Update", or "Confirm" will perform the BIOS update.
6. Power cycle the computer after the update is completed. Many update programs will automatically power cycle the computer. Some will request your permission to do so while others will warn about this before starting the update. A few will prompt you to power cycle the system yourself. If you're forced to handle this yourself:

  •     Completely power down the PC by either pressing the power button or initiating the power      off sequence from the operating system.
  •     Flip the master power switch on the back of your PC to the off position, if applicable.
  •     Wait a minute.
  •     Flip the master power switch back into the on position, if applicable.
  •     Power up the PC. 
7. Clear the existing BIOS settings. Only clear the BIOS if recommended. This is not always necessary, depending on what features have changed between the existing version and the updated version. When the PC is powering up, immediately initiate execution of the BIOS utility. For most systems, this is done by pressing
delete
on the keyboard within the first 2 - 10 seconds of turning the computer on. Other systems might use other keys such as
f2
f10
control
enter
, etc. If you don't know the keystroke sequence for entering the BIOS utility, watch the monitor to see if the computer displays it. To clear the BIOS settings, look for an option to "Restore Defaults" or "Load Fail-Safe Defaults". This may be on the main page of the BIOS utility or on the last page of a tabbed menu. Use the arrow keys to navigate, and follow the on-screen instructions. When complete, save the settings and exit the BIOS utility.

8. Configure the BIOS. If you know the settings you want, change them now. If you have never changed BIOS settings before, it is not required to do so. Most PCs will function just fine using the default BIOS settings

Tips

  1.  BIOS updates may be released to fix existing bugs, add support for new hardware and standards or add functionality. Read the release notes or other documentation for the BIOS update you're considering to see if the update will benefit your PC.
  2.   If your system is currently working well, perform a BIOS update only if you're willing to part with it (for an extended period of time) in the event of a critical failure. System builders and motherboard manufacturers will often repair systems and motherboards that failed to take a BIOS update, provided they are still under warranty. Yet, this process is a lengthy one, often involving the following steps:
  •   Contact technical support and verify the problem is related to the BIOS update.
  •   Obtain a Return Merchandise Authorization (RMA) or similar tracking number.
  •   Ship the product back to the builder or manufacturer.
  •   Wait for approval (testing) and repair or replacement.
  •   Wait to receive the product shipped back to you.
    If the BIOS firmware has become corrupted and you have a similar motherboard with the same CPU socket and a BIOS chip of the same type, you may be able to recover your corrupt BIOS

Warnings

    Make sure to obtain the BIOS upgrade software from a reliable source. Downloading a BIOS from sources other than the manufacturer's web site is risky. For example, versions from the same BIOS software developer for one manufacturer's motherboard may not work on a different manufacturer's motherboard. Using the wrong BIOS or version might "brick" the board, thereby requiring either a BIOS replacement or reprogramming of the BIOS by the manufacturer and rendering the computer unable to boot until that is done.
    Make sure the electrical power source is reliable when flashing a BIOS. Any sizable fluctuation or loss of power during a flash process can corrupt the BIOS. Therefore, never power down or reset a PC when flashing the BIOS. If flashing the BIOS from a booted OS, first disable all unnecessary applications and background processes.
    Avoid updating the BIOS unless you know exactly what you are doing. Failure to follow a manufacturer's directions and precautions may corrupt the BIOS as well.
