On botnet

BotNet, zombie network and network of bots is a group of computers that are used for discrete data such as spam and send viruses to other computers on the Internet. These measurements are performed by malicious programs, without the knowledge of users. These malicious programs mainly consist of viruses, Trojans and worms.

The Botnets can also to attacks by denial of service used, including many robots at the same time on a specific server, so more than the bandwidth of the server and crashing this journal. This technique is particularly effective if the botnet is large and contains thousands of computers. Many advanced malware can even spread itself via e-mail while the malware for small computer networks zombies do not have this capacity.

BotNets are programmed so that it is difficult to find and analyze. Usually, they receive instructions from their creators by IRC (Internet Relay channels).

Therefore a day based on the best way to protect your computer is right, frequently analysis and update your antivirus and firewall software. Special sensors called "honeynets" on the Internet has established the characteristics of the computer with a known security vulnerabilities in an effort to mimic these networks to attract hackers and malware creator runway. She heard recently that Kaspersky Labs (creator of Kaspersky Anti-virus) stated that botnets are a threat to the Internet community over individual viruses and worms.
