ABSTRACT
Antivirus software is one of the most widely used tools for detecting and stopping malicious questionable and unwanted files. However, the long term effectiveness of traditional host-based antivirus is. Antivirus software fails to detect many modern threats and its increasing complexity has resulted in vulnerabilities that are being exploited by malware. These limitations motivate a fundamentally new deployment model for malware detection provided by antivirus software. We advocate a new model for malware detection on end hosts based on providing antivirus as an in-cloud network service. This new model provides several important benefits: Better detection of malicious software: Antivirus engines have complementary detection capabilities and a combination of many different engines can improve the overall identification of malicious and unwanted software. This model enables identification of malicious and unwanted software by multiple, heterogeneous detection engines in parallel, a technique we term N-version protection. Eliminating the impact of antivirus vulnerabilities: By moving the complexity of antivirus engines to the network service and isolating the engines within virtualized environments, CloudAV eliminates the impact of the numerous vulnerabilities present in antivirus engines that may be leveraged by an attacker to compromise a host. Retrospective detection of previously infected hosts: When signature updates are received, previously analysed files can be re-scanned, allowing the detection of malicious software and identification of hosts that have been infected by them. Enhanced forensics capabilities: Information about what hosts accessed what files provides an incredibly rich database of information for forensics and intrusion analysis. Such information provides temporal relationships between file access events on the same or different hosts. ii

CHAPTER 1
INTRODUCTION
A life without computers cannot be imagined in the present life style where it plays a very important role though it might be any field one chooses from the millions. Computer is vulnerable to attacks which are most dangerous and hard to handle with. Just like humans even computers are attacked by "viruses". A virus can be in a form of worm, malware or Trojan horses anything that infects the computer. The common source of these viruses is World Wide Web where a malicious person can spread the malware very easily. Many researchers found many methods or procedures to stop the attacks of virus that came up with many techniques or software to remove the viruses which are called "Anti-Virus" software. A computer virus spreads into the computer through emails, floppy disks, internet and many other sources. The spreading mechanism is usually from one computer to another where it corrupts data or deletes the data from the computer. The viruses mostly spread through internet or through emails which may have some hidden illicit software where the user unknowingly downloads the material into the computer. A virus can attack or cause damage to boot sector, system files, data files, software and also on system bios. There are many newer viruses which attack on many other parts of the computer. Viruses can spread by booting the computer using the infected file, executing or installing th...
