John is complaining that his contacts are receiving continuous e-mails sent from his ID without his intervention. Which of the following could have caused this?
  1. A DoS attack
  2. A back door attack
  3. TCP/IP hijacking
  4. A computer worm
Explanation
Answer: D - If there is an issue with continuous e-mails being sent from an ID unknowingly, the computer is most likely infected with a worm.

Key Takeaway: A worm attempts to replicate using whatever means available. In this case, the worm may not even reside on John’ssystem. The worm may have been in a system with the hisname in the address book. Perform a thorough scan to remove the worm.
