Yes, see Jeff virus description (from http://www.teyko.com/View.aspx?id=297&name=Jeff+v1.31)

"While altering the startup-sequence the virus uses a very aggressive solution: The space which is needed to add the filename of the virus will be cut from the original startup-sequence at the end. Take a look at the following unaltered startup-sequence of an Amiga disk:

C:SetPatch QUIET
C:Version >NIL:

After alteration by the virus (assuming Aloisius as filename) the (above) startup-sequence looks like this:

Aloisius
C:SetPatch QUIET
C:Vers

As you can see the resulting startup-sequence is corrupted because the AmigaDOS will search for a command C:Vers instead of C:Version. This means that the last command won't be processed anymore but "ignored" (infact it will raise a command not found exception to be precise)."
