Foolishly let some girl charge her phone on my laptop, how do I make sure she didn't install a virus or steal files or something?
So I'm sitting at a cafe and some girls come sit down really close to me and start talking and one of them asks if she can plug her phone into my laptop to charge it. I'm bad with technology so I didn't even think for one second how it would probably be a bad idea to let a stranger plug a USB into my laptop. I let her charge her phone and then realized 5 minutes later. I didn't see her doing anything on her phone she just plugged it in and sat back down. Yeah it was really suspicious and weird but luckily there's no important data on my laptop I just play games on it and use the internet for school work. How do I make sure my computer is safe?
