My friend says I've given him a virus. His wifi wouldn't work so we plugged his ethernet cable into my router to get online. He got a virus and says its my fault. I say if there is a virus he got it from the internet and not me.

Who's right?

If we are talking about strict definitions, then viruses don't leap across PCs. However, there are WORMS, which do spread from PC to PC, like the old "Code Red".

I know I can get a virus from another pc but I wasn't aware I could get one from an Ethernet cable. Are you sure about this?

Yes, there are worms that can spread from computer to computer on a network. I got infected by one several years ago and noticed when I would clean a computer and then another one, the worm was right back on the first one. It had me going for a while until I disconnected all computers from the network and cleaned them all before reconnecting them. In my case it was a worm that looks for computers with the administrator password blank.

Well the two computers weren't networked, per se That is, you can't see the contents of one pc on the other pc. I was not aware you could get a virus from JUST an Ethernet cable. That's a new one for me, thanks.

While there is malware that can spread over a network, it really isn't that common. Still, you couldn't spread the malware without file sharing enabled. The Internet is indeed a much more likely source for any infection. Personally, I believe that malware authors don't even have to spend any effort making their warez sneaky and stealthy; it's more cost effective to write simple programs and shotgun them all over the Internet.
