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.
