worm
It is a destructive virus that rewrites itself and is an executable program with its own code. It usually destroys the program it infects.
emulator is a program that allows a computer to emulate another program . This usually does not cause a virus
It will, if you (or the virus) tells it to. However, even if a virus is transferred to another computer it will not run on that computer unless you or another program executes it, or unless the virus is able to exploit some security vulnerability in another program in order to run. A router will not transfer viruses to another computer on its own.
It is a virus that is buried inside another program. SO when the program is run the virus does its thing. That is why a good virus detection software package is important and it is kept up to date.
Host Program
Host Program
Generally, a computer virus attacks a file/program, and then injects a bunch of complex direction codes that make the program a zombie. So the virus basically kills and then mutates the code of a program, either making that infected program another copy of the virus that attacked it, or a powerhouse factory that automatically makes copies of the virus, which means that the program now is like a mass production factory making copy after copy after copy of the virus.

The anti virus program called AVG can be downloaded for free from Cnet's website. AVG's website is another place where the anti virus program can be downloaded from.
"True" viruses replicate by injecting their code into another executable program. Most likely, the "host" program is a commonly used application such as Microsoft Word so that this guarantees the virus is able to successfully replicate. When the infected program is executed, control diverts to the virus, which the copies and infects another program, and then returns control back to the host program. Long loading times for programs are a common sign of virus infections.
You can get a USB anti-virus program using another computer then you can plug it into your computer with the virus and then perform a scan and it should be completed by removing or to quarantine the virus and your computer should not have the virus anymore.
