Resource summary

1 Worm Virus
1.1 A worm is a small program that moves through a computer system and memory randomly changing or overwriting pieces of data as it moves. It spreads around the computer network trying to make as much damage as possible.
2 Trojan Virus
2.1 A Trojan horse is a standalone malicious file or program that does not attempt to inject itself into other files, unlike a computer virus, and often poses as a real file or program. Trojan horses can make copies of themselves, steal information, or harm their host computer systems. You won’t notice it being there, it will sit in there, until it gets all the information it needs. It will look like it is meant to be on your computer.
3 Viruses
3.1 A computer virus is a computer program that can copy itself and spread from one computer to another. Anti-virus programs check for a great many problems, and generally protect your computer very well. But when your computer is infected, it’s always a good idea to occasionally use a second program to get a second opinion to make sure your system is free of malware that anit-virus programs don’t always detect.
