Probably downloaded it
Their friend probably downloaded the malware. There is a basic difference in core system used by Apple and Linux - both Unix based.Windows 7 still uses a lot of the "exe" and "dll" files that were on early systems - sure they may have been tweaked and upgraded, but probably some haven't been changed in years. When you build on a bad base, you get a bad system. Now if IBM's mainframe S/W could be made "PC friendly", I don't think you would see much in the way of malware (unless someone downloaded it). I remember an article in 2600 a while back where they tried to hack into IBM's VM system and could not. It seems all the "hacking" is predominantly done to Window systems or through the backdoor via a WIndows work station with access to a secure mainfram (even those used by the government).
