They can infect other files when an infected program is run from floppy, hard drive, or from the network. Many of these viruses are memory resident. After memory becomes infected, any uninfected executable file that runs becomes infected. E.g. Snow.A, Jerusalem, Cascade.

22. Macro Virus: Macro are mini-programs which make it possible to automate series of operations so that they are performed as a single action, thereby saving the user from having to carry them out one by one. Macro viruses infect files that are created using certain applications or programs that contain macros. They are platform-independent since the virus itself are written in language of the application and not the operating system. They infect documents created from Microsoft Office Word, Excel, PowerPoint and Access files. E.g.W97M.Melissa,Bablas,WM.NiceDay,W97M.Groov.

23. Trojan Horse Trojan horses are impostors that claim to be something desirable but, in fact, are malicious. Trojan horse programs do not replicate themselves. Trojan horses contain malicious code that when triggered cause loss, or even theft, of data. E.g. Trojan.Vundo Retrieving user’s critical information. i.e. name, password. Erasing or overwriting data on a computer. Spying on a user to gather his information like browsing habits, sites visited etc.

25. WORMS Worms are programs that replicate themselves from system to system without the use of a host file. The worms are spread through networks like LAN, WAN and also through Internet. There are various ways by which a worm spreads, through Internet like E-mails, Messaging and Chats. Worms almost always cause harm to the network, like consuming network bandwidth. E.g.W32.Mydoom.AX@mm

26. SPYWARE: It is a type of malware that can be installed on computers, and which collects small pieces of information about users without their knowledge. The presence of spyware is typically hidden from the user, and can be difficult to detect. Typically, spyware is secretly installed on the user's personal computer. ADWARE: It is any software package which automatically plays, displays, or downloads advertisements to a computer. It is a type of malware which steals information. Example Bonzi Buddy , an application marketed as an "I ntelligent Software Agent ", corrupted many of the user's system files, forcing the display of many obscene advertisements.
