Scam call - someone was stating there is something wrong with my computer

Called saying something is wrong with my computer asked how they got my number and he said my ip address is attached to my phone number.  I told him our computer is in girlfriends name so that doesn't make sense and he asked if he was talking to myself so he ķnew my name somehow and when I said no he hung up.

Trying to rip you off by placing virus on your computer. These clowns should be shot!

I don't answer unknown numbers. They didn't leave a message.....
