Logic Bombs and Other Threats

Logic Bombs

Like other viruses, logic bombs are designed to cause harm to your computer. Logic bombs, however, only trigger when specific conditions are met. For example a computer programmer may insert code into a payroll program that deletes files if her name is not found on the list. In other words the files will be deleted if she is ever fired.

Other viruses, called time bombs, may only detonate on a specific date or time. An example of this is the Jerusalem virus which, every Friday the 13th, deletes all the files on an infected computer.
