[comp.virus] Possible virus or trojan

     I've got a strange Mac problem and need help.  Monday night, one
  of my colleagues allowed a friend in to the office to steal Mac software
  (using his old Mac disks, of course).  After the appropriate cussing-out
  and running-off, the machine in question (Mac SE, 20Mb hard disk, System
  6.0.3) started acting funny.  Symptoms:

       a.  We can't find any virii on it with Disinfectant 1.6 or 1.8
       b.  Suddenly icons can't find their applications
       c.  Applications are increasingly unable to open data files or
           find them
       d.  The parameters of applications like Versaterm are unaccountably
           changing themselves i.e. the baud rate changes itself or the
           Kermit parameters change for no known reason
       e.  The options of the System and Desktop are unaccountably changing
           themselves i.e. the sound bar is turned up without anyone having
           done it.
       f.  There are more system bombs, and other disk and ram error messages
           than I've ever seen before in two years of working with Macs.

      We're to the point now of chucking months worth of data and reformating
  the hard disk and starting over.  Any suggestions?  Any help?
  Anybody seen anything like this before?
