The other day I got the password for our school's Wifi but even though that's the case, I still can't connect. So I visited the guys at my school's IT department and they said they need to borrow my laptop so I can connect to the network. I gave it to them.
Few minutes later it was returned to me and true enough I was able to connect to the network.
But I'm very worried about what they did to my laptop. I was unable to ask them and I'm not going back there anytime soon.
If they installed something, how do I know? (No new programs listed on control panel, but I still have doubts). I'm really worried they installed something that will allow them to control my laptop.
How do make sure nothing was installed?
I'm thinking about using AVG antivirus to check, is it good enough?
What do you think are the things that they have done that they hope I won't notice?
