I have read your thread and I do not believe you are a troll. I do believe
you have read quite a bit about computers and just because you posted an
intelligent question, but at the same time did not answer your own question
based on the knowledge presented, you might have a problem as pn one hand
you present a problem but take no action for yourself.

In answering I must do so without belief you have no knowledge because the
answer will run counter to what you have read. First and foremost - a
computer has two types of memory - ROM (read-only-memory) and RAM (random-
access-memory). Your ROM is within your Chip (Pentium, Celeron, Athlon,
etc). This ROM is virtually impossible to compromise. Your RAM can be
compromised, but only if an instruction to do so exists somewhere.

The only place code can be introduced is on your HD. Your comment about
wiping a HD is not correct. A HD can only contain information in binary
form. If you zero out your HD that means writing a 0 to every portion of
your HD nothing can exist except zeros. Period. A machine does not have a
spirit - it is a machine.

The trouble comes with using Windows programs. Use a DOS program to tell
every sector of your HD to contain ZERO and ZERO you will get. Windows
cannot do this as it relies on the HD for its program. Remember DOS means
Disk Operating System so it exists totally independent of the disk - it
tells the disk what to do and does not need the disk for anything.

You have picked up a bad bit of code and it is on your HD. The way to get
rid of it to drop to DOS from a floppy and ZERO your HD. I would post ZAP
a program from IBM, but you did not state what type of HD you have. Larger
HD's (Over 9GB approx) that do not use a standard 13h interface can get
destroyed by using such - especially SCSI drives. You can use ZAP - I have
two Seagate Barracuda's 7200 ATA's but you really need to know how to
handle the internal calls from BIOS.

The newer HD's are not friendly, but all of them are supported by
www.jetico.com in the form of BC-Wipe. Download the program and you will
find a DOS program called BCWIPEPD.EXE. Place this small program on a
bootable floppy and run it from DOS. It will totally ZERO out your HD and
unless you really are paranoid one pass is enough. Then re-install your OS
and use whatever protection you wish.

But remember you might run into this problem again - so create a dual-boot
HD if you can and from the alternate system make a zip copy of your
partition using WinRAR so in future if it happens again, you only need to
ZAP your drive and reload from a CD if you have a CDR.

Again, I will not be against you as you stated a serious problem, but you
stated it so well that folks have trouble thinking you can not see how easy
it is to resolve. Hope this helps.
