SPTD.SYS - problem, system won't boot

[SARS]

I have two computers, one with DAEMON [called Computer A],
and one without DAEMON [called Computer B]
(Both Windows XP, A is SP1, B is SP2)

one day, I realized my computer A was slow
so I ran anti-virus and spyware search.
SPTD.sys file was found infected so I tried to fix it and failed.
tried to rename and failed, so I just erased it.

next thing I know, when I tried to log on to dif. account,
I automatically logged out. And was back to WELCOME page
of Windows XP (page that shows all the user accounts)

so I reinstalled Windows XP on Computer A, thinkning it was Windows problem.
but it couldn't find "SPTD.SYS" and showed me the
BLUE SCREEN OF DEATH!

I thought it was a virus so I put the Hard Drive of Computer A [called, E drive] into Computer B [called, C drive],

Computer B is currently running on C Drive.
and E Drive is just connected as a secondary Drive
after 15 minutes of internet searching,
I found out SPTD.SYS is for DAEMON tool.

So I figured.
"If I uninstall DAEMON from Drive E, everything will be fine"

WRONG!

I coudln't uninstall it because
the uninst.exe file didn't work with error message
"Setup is unavailable to validate installation"
and I can't boot from Drive E
because I'm missing SPTD.sys

Can anybody help me out?
[It is DAEMON 4.8]

Thanks in advance

P.S: it does not show up in Add/Remove program either.

If SPTD layer is not present, Daemon Tools won't work, thus you can just delete its installation folder.
Did you try to install SPTD layer v1.47 yet?

I cannot boot from a drive with DAEMON.
how am I supposed to install SPTD and
register it in registry if I can't boot from the disk with DAEMON?
