Zombie is one such threat against which the computers must be secured. Many times your computer does not show any abnormal behavior like corrupting files or deleting information but would show all your confidential information to some others to which you are connected. Such a computer is termed as a zombie in computer science language. The zombie would get compromised with a hacker on the internet to do whatever he says. This can be done using the Trojan horses to perform any tasks on some other computers. This means unauthentic access and the user is completely unaware of it. Botnets of these zombies are used to spread emails and spam on the network which can later be used to launch attacks like the denial of service attack. The users are not known about their situation and hence they are termed as zombies which mean something done without self awareness. McAfee antivirus is the best tool to prevent zombie in your computer. You can always use a McAfee coupon code to get the cheapest price.
The botnets are the main base of making a zombie. The bots means a malware type which helps the attackers to completely control the infected computers. The computers are known as zombies that are infected by the bots. There are nearly thousands of the computers over the networks which are affected by the bots. The attackers can easily gain the list of all such computers and they can launch the denial of service attacks to activate them. If anybody tries to trace the hacker by attacking in return then they would find a victim and not the real attacker. This is the benefit to the attackers that they can attack any computer without the fear to get caught. More details:
