Malware is an abbreviated term meaning "malicious software". This software has a capability to gain access or infect a system without the knowledge of the owner. In this paper, we have tried to provide brief information about different types of malwares known till date such as virus, rabbits, botnet, adware etc. Apart from those we have mentioned the cure to it i.e. intrusion detection. We have described various techniques of intrusion detection such as signature based, anomaly based, behavior based etc. Methods for implementing these techniques include neural networks, data mining etc. A brief description of Intrusion detection system is also provided which is a software application used to monitor the network and system activities and also to detect malicious actions. The objective of this paper is to provide complete study about the types of malware, techniques and methods of intrusion detection, challenges and applications.
