After removal of malware from computer Windows XP SP3 will not boot. Error message C:/windows/system/ command.com improper parameter.

The answer to the related question didn't work. I tried to repair the xp installation, but the same error "C:/windows/system/ command.com improper parameter" appeared  about 1/3rd of the way through the repair process and cannot continue.

I installed SP3, and after removing some Malware and running CCleaner in safe mode, the subsequent reboot yielded this error message.

any ideas?

It sounds like one these files has become currupted (command.com, msdos.sys, io.sys or drvspace.bin).

If you are using the original windows XP CD then the files may be different versions to those created by Windows XP Service Pack 3.

I would try and roll back to before you installed windows xp service pack 3 and then run ccleaner again and re-install service pack 3.

If that still doesn't work i would try rolling back to xp sp2 and use the windows xp service pack 2 boot disk (utility available from http://www.microsoft.com/downloads/details.aspx?FamilyId=535D248D-5E10-49B5-B80C-0A0205368124&displaylang=en).

Once you get to the command prompt, type sys C: and press enter.
