Wat. Do you know what that means? That sounds like the name of a generic virus. You can't just magically send viruses/virii to people. You need the host of the virus whether that be a rouge executable or some other infected source.

If you have possession of this virus then you still wouldn't be able to just up and send it to someone and expect it to cause damage. They would need to download it and they would need it to successfully execute in order to infect this person.

If you mean a way to automatically infect someone with a virus through Skype that would be impossible without some form of exploit in Skype. So if you don't have that you're out of luck either way you look at it. This act is unethical anyway, so yeah.
