When many computers have been hacked to turn them into zombies computers, we call such a group a Botnet. Those computers are being used by cyber criminals to send spam emails and/or to attack websites. If your computer is going to get infected by some “bots”, chances are it will become part of a Botnet and your PC will then be another zombie one of that group. Your computer will be controlled at distance by some hackers using a control server and bot-herder command. Those Botnets can hurt networks, websites, personal computers, and more. They are one of the most dangerous problems over the Internet. Problems like viruses, malware, spyware can also be distributed via those Botnets, besides all the spam emails. Another popular attacks on servers being done by those Botnets are the Denial of Service (DoS) and the Distributed Denial of Service (DDos). It is an attempt by those compromised computers to overload a website with many requests at once, thus trying to shut it down because of the excessive amount that the server cannot simply handle.
