Solution for The system is not suitable for running MS-DOS and Microsoft applications error. We cannot run MS DOS application such as Command.com, Foxprox, Edit, etc. Some of the cause is virus such as vjirh.exe and autorun.inf that found hidden in C:\.
The solution is running Windows XP in Safe Mode and delete those file. Restore file config.nt, autoexec.nt, and command.com that found in C:\windows\system32.
I have seen the corrupt command.com file is more than 1,000,000 bytes while it should be around 50,620 bytes only.
