Today’s threat landscape is very complex. Cybercriminals use a wide range of threats to hijack people’s computers and to make money illegally. These threats include Trojans of many different kinds, worms, and viruses, and employ code that is designed to take advantage of vulnerabilities in the operating system or applications. Cybercriminals also employ a range of sophisticated techniques to hide malware activity or to make it difficult for anti-virus researchers to find, analyze and detect malicious code.
