I have a Desktop computer and have a tenant in my house who has a desktop computer. He is a computer geek and I had a few questions before I got in over my head. I offered to get a wireless router and he could get the USB card to get my internet service for free. This was before I knew that he would then have access to my computer.
I'm statring to do some research and need your help.
~ If we are on the same network, can he access my computer files (Especially considering he is a Computer geek).
~ Can I get a virus from him if he got one on his computer?
~ Is there any fool proof way to keep me safe from him entering my files?
~ Would I be better off just telling him that he'll need to have a new cable line run to the house for his own computer?
~ Or if you have any other ideas that I could offer, would be greatly appreciated.
Thank you in advance!
