Computer viruses consist of malicious programs designed to modify programs by injecting malicious code into an infected computer. Virus attacks usually use self-replication over the network. Successful virus replication leads to a higher level of infection on a computer system connected to an infected network.
Cyber Criminals create computer viruses for a variety of reasons. The best of them sabotage the network to deprive the organization of essential services, make a monetary profit, and prove that a secure IT environment can be hacked. Attackers use new technologies to develop and execute more complex computer virus attacks.
Statistics show that at least 6,000 new viruses are created every month.
