Renee, if I'm reading Igor's post correctly, well, I think it's not good to leave a live link to an infected file here...
People could click unadvertisely in it
Ktl, if the system restore is infected you will 'bring back' the infection when you try to restore your 'things' of an earlier time...
Maybe you can clean both of them (in the computer and in the system restore) at a time, but, only maybe... we can't be sure.
System restore could fail in most times when you need a 'deep' restore back (programs). It's not a tool for that. You need a backup tool. Microsoft is selling apples intead of oranges with this tool
