  12. Removing a Virus – Safe Mode • Safe Mode is a basic configuration of Windows – used primarily for debugging • Minimum number of items are loaded • This means no extra programs can start – AIM, AOL, or viruses! • If a virus doesn’t start up, you can find the file and delete it

  13. Removing a Virus – System Configuration Editor • A look at system files • Look for ‘run=‘ and ‘load=‘ lines that might initialize a virus

  14. Removing a Virus – System Configuration Utility • A more intuitive look at system startup • Interesting tab is ‘Startup’ • Shows you programs that load automatically – do any look out of place?

  15. Removing a Virus – Registry Editor • Difficult – not for the faint of heart! • Must be very careful in the Registry • Viruses often affect the same Registry locations <HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run> - Startup <HKEY_CLASSES_ROOT\exefile\shell\open\command> - Executables
