What a ball-buster this one is!


Everytime I go to boot up win 98 my wallpaper comes up, no icons appear and then the starup menu (Explorer bar) flashes on then off for a brief second......Then nothing!

I have a compaq deskpro-EN that used to work just fine....
I don't have the original 98 CD-ROM
I've used every boot disk I could get online

I have tried so many things:

FDISK /mbr
xxcopy
Loading from boot disks
other DOS based Boot Sector tools

I can't figure what the heck went wrong.
There is also a message in one of the DOS lines while the machine trys to boot up that says Start-menu Trojan detected.

could this be it? Is there a MBR virus that is prohibiting the launch?
Is there a good anti-virus or other DOS Based program that can help me?
I can't even boot in safe mode so I can't use any Windows based apps to try and fix this thing

IT'S A NIGHTMARE!
Am I the only one having this problem???
