Well first I'd start by identifying whether the OS is capable of hosting the virus  |
Easy to say. Not so easy to do.. I can think of one way they can do it remotely. When you access something with a browser, your browser sends a series of headers that include the platform, OS and browser sending the request. You could (theoretically) check for all Windows PCs this way.
I can think of two problems with this.
- It relies on the application accessing the net actually sending these headers. I am pretty sure that only web browsers do.
- It is easy to forge/alter these headers. Opera does this so that it can appear to be Internet Explorer. I am pretty sure virus writers would find a way to use these headers to make it appear the machine being checked is running Linux.
