A: A virus attack is when a program or macro is executed and the virus is implanted into another executable. A virus can be used to implant the code for the illicit server attack, but the actual illicit server attack is when the service or daemon is running.
B: A hijacking attack is when someone gets in the middle of a transaction and takes over the transaction, spoofing himself as the original transaction partner.
C: A man-in-the-middle attack is also when someone gets in the middle of a transaction between two servers and intercepts the transaction flow. This differs slightly from the hijacking attack. In the hijacking attack the man-in-the-middle actually cuts in and impersonates one the partners, but in a man-in-the-middle attack, the intervening party only eavesdrops and listens to the stream.
