A family member continually needs me to reinstall his PC after it gets viruses and spyware. He claims that he never downloads anything but evidence suggests otherwise. Unless there is some way that watching 'videos' can get spyware on there. AFAIK the computer is kept up to date.

Possible solutions?

1. Make a login where its impossible for him to install anything. Windows 7 standard account doesn't appear to be enough. Is a standard account enough here? I tried this once before and he still seemed to get IE toolbars installed up the wazoo
2. Somehow make an automated image where if he 'messes up' or even on log off the computer restores the whole drive image. Similar to what I've seen in Kinko's
3. Something I've not thought of....

And I know you are all going to say 'stop fixing it you are an enabler'... yes I know but I'm not going to have another fight with my wife over helping her family... right now I'm doing this to keep her happy not the idiot with the 'video' addiction ;-) So the name of the game is minimizing my overhead.
