While most viruses eventually cause direct damage, many modern malware suites are extremely subtle in their attacks. The goal is to infect as many systems as possible, steal information and allow the author to take over the subverted "zombie" systems for his own use.

Once a malware author has a large number of systems under his control, he can use them to attack servers by flooding them with requests from hundreds or thousands of systems at once.
