I discovered a virus on the bootrecord of my machine.
This virus is the Quandary Virus.

I have tried three virus checkers and they have all said they cannot 'kill' or 'remove' this virus.

I need some help, as writing to any kind of disk causes it to also write the virus to the disk.

Formatting both my hard drives is an option, but i don't want to lose the data on both of them.
does anyone have any suggestions to getting the data off and not the virus, or just killing the virus altogether.

Mabyee if i can delete my bootsector?

Help me!!

(p.s. i can only offer 75 points as thats all i have)

try this if you are using any of the windows 95, or 98 version. Using a bootdisk that can be obtain from www.bootdisk.com boot from the floppy. Make sure you obtain the current os version. Type fdisk/mbr to restore your system mbr and then sys c: to recreate the system file. Hope this will work. Sometimes the boot sector virus can be very nasty.

According to:
http://securityresponse.symantec.com/avcenter/venc/dyn/32585.html
- Area of Infection: Floppy Boot Sector, Hard Disk Boot Sector, Master Boot Record
 Characteristics: Memory Resident

Then kahlean' clean should suffice, where you boot system from a known good boot diskette for the O/S version that is installed on HD. (you should always have one handy, Now you know one reason why)

Deleting your boot sector would work, but then you'd have to know how to do that, and then rebuild the entire HD.

Do not forget to clean any diskettes that have been infected and don't boot them until you do. Where did you get the bugger?
