Recently I have found KernelFalseCheck MS-Dos Batch file in my start up of windows with the command %systemroot%\system32\dumprep.exe 0 -K . And I noticed that everytime I opened programs, it shows as microsoft error report msg pop up and couldn't able to open programs. Finally I have to reboot with bootable disk to command prompt..then I had to use Debug Dos command to clean out Harddisk Volume 1. Then using FDISK command to delete partitions and create new partition. After that I had to format harddisk to reinstall windows. But the thing is as soon as you are on network, those backup files reinstall and replace that ms-dos batch file in start up again. I have tried so many times to clean that file but finally I had to wipe the whole harddisk again and reformat and reinstall windows then configure setting to block ports in firewalls 0-65535 TCP/UDP incoming Local and Remote Ports. Since then, I haven't got same problem on my machine.d
