Generally speaking yes, most viruses are either.exe or screensaver programmes disguised as something else or part of another programme but they generally need to be run in order to do anything. Most antivirus programmes will alert you that a program is infected with a virus and prevent you from running it.

How virus can enter in a computer?
A computer virus is a computer program that can copy itself and infect a computer without the permission or knowledge of the owner. 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] In order to replicate itself, a virus must be permitted to execute code and write to memory. For this reason, many viruses attach themselves to executable files that may be part of legitimate programs. If a user attempts to launch an infected program, the virus' code may be executed simultaneously. Viruses can be divided into two types based on their behavior when they are executed. Nonresident viruses immediately search for other hosts that can be infected, infect those targets, and finally transfer control to the application program they infected. Resident viruses do not search for hosts when they are started. Instead, a resident virus loads itself into memory on execution and transfers control to the host program. The virus stays active in the background and infects new hosts when those files are accessed by other programs or the operating system itself. http://en.wikipedia.org/wiki/Computer_virus#Infection_strategies

Short answer: possibly.First of all, to contract AIDS, the person must be infected with the HIV virus. If the person is infected with the HIV virus (which causes aids) and you get their blood on an open wound, or a mucus membrane such as the mouth, it is possible. If you get some infected blood on normal skin that is healthy, the chances of you contracting the HIV virus are slim to impossible (?).
