Viruses in different platforms
PC viruses
Viruses are mostly written for PC-computers and DOS environment. Even though viruses are made for DOS environment, they are working also in Windows, Windows95, Windows NT and OS/2 operating systems. Some viruses like boot sector viruses, do not care what about operating systems.[1]
Macintosh viruses
Macintosh viruses are not as a big problem as PC viruses are. There are not so many viruses in Macintosh operating system. Macintosh viruses has been found mostly from schools.
How many Mac viruses there are? I found out that there are about 2-300 Mac-specific viruses. There are virtually no macro viruses which have a Mac-specific payload, but all macro viruses can infect on Macs and other platforms which runs Word 6.x of better.

Other platforms
Viruses can be found from in almost any kind of computer, such as HP calculators used by students like HP 48-calculators and old computers like Commodore 64 and Unix computers too. [1]
In general, there are virtually no non-experimental UNIX viruses. There have been a few Worm incidents, most notably the Morris Worm,. the Internet Worm, of 1988.

There are products which scan some Unix systems for PC viruses. Any machine used as a file server (Novell, Unix etc.) can be scanned for PC viruses by a DOS scanner if it can be mounted as a logical drive on a PC running appropriate network client software such as PC-NFS.

Intel-based PCs running Unix e.g. Linux, etc. can also be infected by a DOS boot-sector virus if booted from an infected disk. The same goes for other PC-hosted operating systems such as NetWare.

While viruses are not a major risk on Unix platforms, integrity checkers and audit packages are frequently used by system administrators to detect file changes made by other kinds of attack.

A computer virus is a computer program that can copy itself and infect a computer. The term "virus" is also commonly but erroneously used to refer to other types of malware, adware, and spyware programs that do not have the reproductive ability. A true virus can only spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.[1][2]

The term "computer virus" is sometimes used as a catch-all phrase to include all types of malware. Malware includes computer viruses, worms, trojans, most rootkits, spyware, dishonest adware, crimeware, and other malicious and unwanted software, including true viruses. Viruses are sometimes confused with computer worms and Trojan horses, which are technically different. A worm can exploit security vulnerabilities to spread itself to other computers without needing to be transferred as part of a host, and a Trojan horse is a program that appears harmless but has a hidden agenda. Worms and Trojans, like viruses, may cause harm to either a computer system's hosted data, functional performance, or networking throughput, when they are executed. Some viruses and other malware have symptoms noticeable to the computer user, but many are surreptitious or go unnoticed.
