First I hope Microsoft gets thier act together and get a signature in
defender that will fix Qoologic & QoolAid.
You said defender found it but could not remove it. Try running the scan
again write down the files it detects and cannot remove, reboot in safe mode
and manually delete the files. Its worth a shot, I have not tested this
process.
Cause:
The missing or cannot find hal.dll, \windows\system32\hal.dll, or
\winnt\system32\hal.dll error message may be experienced on a Microsoft
Windows 2000 or Microsoft Windows XP system when the boot.ini becomes
corrupted or when a user is attempting to dual boot a computer.
Solution:
Verify that the computer boot.ini is present and not corrupted
Verify the boot.ini file is found on the computer by using a boot diskette
or use your Windows CD to get to the MS-DOS "C:\>" prompt.
From this prompt edit the boot.ini, verify that it is pointing to the
correct operating system, and that no anomalies are found within the file.
Additional information about editing the boot.ini as well as additional
information about its available options can be found on document CH000492.
Below is a listing of what to verify
If only one operating system is on the computer verify that the boot.ini
only has one operating system listed. In some situations an alternate
configuration line may be added for the same operating system, leaving the
improper line.
Verify that the "default=" line as well as the operating system line are the
same and that they are pointing to the correct operating system.
Verify that the computer has the hal.dll file
From the MS-DOS "C:\>" prompt quickly determine if your computer has the
"hal.dll" file by typing "dir hal.dll /s" at the prompt. If the computer
returns a "File not found" message, the hal.dll has been deleted.
To recover this file boot the Windows operating system CD and choose the
option to "restore", "repair", or "recover". This option will prompt you for
the Windows installation to use, the administrators password and will allow
you to restore the proper file. At the MS-DOS prompt type the below command.
expand x:\i386\hal.dl_ y:\windows\system32\hal.dll
In the above example "x" would be the letter of your CD-ROM drive and "y"
the letter of the drive your operating system is installed on. If you need to
determine the drive letters of your devices type "map".
Additional information about the expand command can be found on our expand
help page.
Reinstall the operating system
If the boot.ini is found on the computer and does not appear to be corrupted
and/or if the hal.dll file is missing it is recommended that you reinstall
your Windows operating system.
