Recently, there were more than 1 million malware including computer viruses, worms and Trojans circulating in the internet from the Symantec bi-annual Internet Security Threat Report. These might be resulted from a huge numbers of new malicious codes being created by the cyber crime groups.

One of the reasons is criminals increasingly using Trojans as their main tool to gain access to other computer and use that route to download and install a variety of other malicious programs. Besides, some malicious installations happen when websites are visited or programs, such as online games are started up. There is also a growth in professional digital criminal underground, these experts are expected to be paid to steal information and aiming for new victims.

Besides, most of the malicious codes are targeted on Microsoft Window's based PC. These malware will utilize popular communication tools to spread worms by sending through email and instant messages, Trojan horses dropped from websites and virus-infected files downloaded from p2p connections. Malware will also seek for vulnerable systems, making their entry quiet and easy.
