While checking your work e-mail, you have received an e-mail warning you about a virus that is currently doing the rounds. What should you do now? Forward it to everyone in your address book.
Forward it to your tech administrator.
Ignore it, as virus checking is handled centrally.
Do an extensive web search to learn if it is a real virus.

D) Do an extensive web search to learn if it is a real virus.

Logical explanation: In the example, it is not a pop-up that you have a virus and instead an email that you have a virus. There is a very likely way that it could be a prank, scam, or a hacker.

Elimination explanation: If we look at all the answers:

A (Forward it to everyone in your address book) makes no sense, so A is eliminated.

Then with B (Forward it to your tech administrator) makes sense because if it was a real virus they may know what to do, but as my 'Logical explanation' explains, it may not be.

Finally with C, it's very irresponsible and should not be done. If it was a real virus there is a possibility it could be someone trying to steal information and more.

This leaves only option D left. :)
