    I doubt this would work.  To introduce a virus into the system, it has to
    be loaded into memory as an active program, not just written to disk.  As
    soon as the virus-infected file/program was launched (and thus became
    active), the A/V program should/would detect its presence and alert the
    user.
    
    The reason pagefile.sys and recycle bins are not normally included in
    default scanning is precisely because in_those_locations a virus is
    essentially benign.  If one were to try to activate it, normal detection
    routines should discover its presence and remove it before any infection of
    files takes place.
    
    Furthermore, only pagefile.sys on specific drive letters is excluded from
    scanning.  So your proposed technique of writing to a non-existant pagefile
    would be precisely the same as writing to disk, which is a detectable
    activity.
