What are Botnets?

The objective of most of today's malware is no longer to damage a PC but rather to penetrate a computer and make it part of a "bot net".

Botnets are networks made of thousands of malware-infected computers, which become bot net nodes or "zombies'. These networks are the foundation of a massive online criminal activity.

Those who control botnets can either use the CPU power and bandwidth of these compromised computers for their own purposes, or rent them out to others, usually to send out enormous amounts of spam, attack websites, or carry out a myriad of other illegal activities.
