Thanks, David. It does raise the question of what "infect" means. <br><br>I take it to mean that the malware copies <b>itself</b> to the file in order to propagate. But I always believed worms were self-contained and did not travel as a parasite. (And I'd disagree that worms are "very similar to viruses" in that sense. It is this distinction that separates viruses from worms.)<br>
<br>This is getting to be a sticky question...<br><br><div class="gmail_quote">On 18 November 2011 12:35, David Dawson <span dir="ltr"><<a href="mailto:David.Dawson@wesleycollege.net">David.Dawson@wesleycollege.net</a>></span> wrote:<br>

WHAT IS A WORM?<br>
A worm is a malicious self-replicating computer program designed to infect multiple remote computers in attempt to deliver a destructive payload. A typical worm spreads by e-mail, in file sharing networks or through unprotected network shares. Widely spread complex parasites usually propagate themselves by exploiting certain security vulnerabilities in the targeted remote system. Most worms can infect and corrupt files, degrade overall system performance and security, steal user sensitive information or install other dangerous parasites such as backdoors or trojans. Worms are very similar to regular computer viruses and therefore can have different malicious functionality.<br>

Do worms infect files? Option D requires that.<br>

The answer is D.<br>
Worms travel across networks unrestricted especially LANs - without user actvity.<br>

Hi,<br>
<br>
I don't like Question 15, as all of the answers, not just C, refer to "infected files". From Wikipedia:<br>
<br>
"A computer worm is a self-replicating malware computer program, which uses a computer network to send copies of itself to other nodes (computers on the network) and it may do so without any user intervention."<br>
<br>
I think it is D, as there should be other ways for a worm to spread other than email (and that requires a user). I am doubtful that Question 20 is B, as that would require the user to have knowledge of where the country is.<br>
<br>
Regards,<br>
Julian<br>
<br>

Great as always Mark,<br>
<br>
I still have my money on scrollable list for question 20, because you don’t need to know where the country is located (which I guess would be one of the facts). Given the question info mentions 200 countries may indicate they want you to think a scrollable list will be too long. However, my iPod song list suggests 200 is catered for easily in a list. We will have to wait and see.<br>
<br>
I’m still thinking about what the main purposes of including the different languages in the question is. Is it just to help you decide not to do C or D or is there more to it? Would you have a different answer if they left this info out?<br>
<br>

A few interesting questions.<br>
<br>
I'm starting on Section B - and looking forward to that ridiculous B5 question with the big clown nose. It's monumentally absurd!<br>
