SCSI Pass-Through Direct (sptd.sys), which is a deliberately misleading name
for how the product is actually used, is a kernel-mode driver installed by
several "cheater" products that attempt to hide an emulated CD/DVD drive
from being scanned. It is used to thwart some virulent seeker copy
protection schemes that try to hunt down if the program (usually a game) is
on a real CD/DVD disc or from an image of one (whereupon they attempt to
disable those emulated devices or simply refuse to start the program).
For example, Daemon-Tools comes with sptd.sys (and, as I recall, you didn't
have an option to not include it in the DT install). Also, when you
uninstall these products, often they do NOT uninstall the sptd.sys driver.
You have to do that manually to purge the remnant files and registry
entries, use an uninstaller that recorded the product's install (so it knows
what got changed to then remove it), like Zsoft Uninstaller, or use the
uninstaller provided for sptd.sys itself (but which is difficult to find
when you start hunting around for info on this driver).

Trying to find the uninstaller or even the author of this driver is
something of a creative and irksome exercise. They certainly seem to want
to hide who they are and the products that use them often do not provide
direct links to the author. The driver's author is at:

Read their FAQ page. This is also where they put the links to their removal
programs. If you are going to remove SPTD then you might as well as also
uninstall whatever product you installed that uses it.
