I know I should know this by now, but I am not sure. I know it's better to ask than to asume Whatever.

I have a friend who lives on campus(FAU) and the university shut her off of the network(basicly - no Internet), because they believe her PC has a virus. She doesn't have an antivirus software installed, so I figured since she is already infected(according to the university), then installing one will probably not do much good, because the virust woun't let me install it anyway. In any case, what I was thinking I should do is get my laptop, hook them up with an ethernet cable and just scan her hard drives using my machine. Is there any chance that I get that same virus if I do that, with the understanding that I woun't be opening any files(except to share her hard drives which I'll do before connecting the PCs)? If anyone believe this will put my machine at risk please speak out . And if anyone has better/more ideas how to fix her PC(or at least scan it) please speak out as well.

Thank you.

P.S. : "Format C:\" is my last resort ). Of course it's the easiest as well.
