82 Occasionally the text "welcome datacomp" appears in my Mac documents without me typing it. Is this a virus?
Most likely not. This phenomenon has been reported for a particular
make/model of third-party Macintosh-compatible keyboard. It appears to
be a practical joke, coded into the keyboard's ROM, that causes the
keyboard to output that text (as if it was typed) after a period of
keyboard inactivity. The only practical fix is to replace the keyboard.
This is, in effect, a hardware (technically "firmware") Trojan Horse--
the keyboard has features or functions that are not advertised and that
will be performed without the owner's or user's wish or permission.
