Question

Quizplus · Accepted Answer

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.
