My fiancée's mother exchanged her laptop for a pawn loan 3 months ago and she bought it back today. The laptop had no password on it. Just turn on the power and your in. Now she is staying with us for a bit and wants our WiFi password so she can connect to the internet with it.
The problem is I am very worried about her laptop compromising the security/safety of my family and their devices. (I.e., In 10 seconds couldn't the pawn owner turn it on and install spyware that could spread to everyone's devices connected too it?!)
I Just wanted to get some feedback from professionals out there on what you would do in my scenario, what are some worst case scenarios and how likely are they too occur? Would you let her login too your WIFI? (Part of me wants to just burn it and buy her a new one)
