By the way, you should be able to run that script (It's just a text file I call "exp.cmd") by putting it in the "Startup" directory under the Start Menu.
I also run a shutdown script. It takes longer, which is why I only run it on shutdown (to run at night, for example).
Here's the contents:
@echo off
echo running F-PROT virus scan...
C:\F-PROT\F-PROT.EXE /AUTO /DISINF /RENAME /HARD /REPORT=C:\virlog.txt /TYPE /APPEND
echo running Spybot scan...
C:\progra~1\spybot~1\spybotsd.exe /autocheck /autofix /autoclose /taskbarhide
reg delete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce" /v SpybotSnD /f
C:\progra~1\eraser\eraserl -file "C:\Documents and Settings\All Users\Application Data\Spybot - Search & Destroy\Backups\*" -method DoD_E -queue -silent
C:\progra~1\eraser\eraserl -file "C:\Documents and Settings\All Users\Application Data\Spybot - Search & Destroy\Statistics.ini" -method DoD_E -queue -silent
echo clearing free drive space...
C:\progra~1\eraser\eraserl -disk all -method Random 1 -queue
As you can see, it combines a Spybot S&D scan (which wipes spyware as well as useage tracks), a virus scan and freespace wiping. The rest is to eliminate extra stuff Spybot S&D leaves behind when it runs.
