    How to Make a Boot Floppy

    I got this "WYX" virus in boot of my WIN2K. I tried to remove it with Dr. Solomon but it says that I need to first boot with clean disk. My question is how to make a boot disk for WIN2K?
    Thanks

    Re: How to Make a Boot Floppy

    Many thanks for your detailed and informative answer. This is what I like about Woddy's Lounge!
    Well you have scared me more. What I was planning was to make boot disks from my desktop and then use them on the laptop to clean up the system. But I guess that may not be possible?
    I wish there was another way of killing this virus as I got lot on the hard disk.
    On the other hand why not I fly back to NY and shoot the publisher who gave me this virus on a floppy <img src=/S/smile.gif border=0 alt=smile width=15 height=15>

    Hi

    1. <LI> You need 5 empty formatted diskettes.
      <LI> Go to Start, Programs, Accessories, System Tools and click Backup
      <LI> Click 'Create Emergency Repair Disk' icon.
      <LI> Insert a blank disk when asked and click OK.
      <LI> When complete, remove and label the disk Emergency Repair.

      <LI> Insert another blank formnatted disk.
      <LI> Insert your Windows 2000 CD
      <LI> Click Start, Run and type in the box :

      d:bootdiskmakeboot a:

      (d = drive letter of your CD-ROM drive )

      <LI> You will eventually be asked for the next, and you will need four in all
      <LI> Label them Set Up 1,2,3,4 (with the appropriate date)
    What this back-up set of 5 disks allows you to do is to Restore your Registry. You will need the ERD made in parts 1-5, your 4 set-p disks and your Windows CD.
    Using the ERD restores your settings to the time you first installed Windows 2k. Using the Set-Up disks restores the settings to those current when you last updated the disks.

    However, in your case, you have already got a virus infection, and some of your vital files may have been corrupted. In that case your set-up discs may well be useless.
    I'm afraid you may need to delete your Windows directory and start from scratch. In fact, I'd re-partition and re-format the hard disc first. Sorry, but that's the sort of inconvenience viruses cause if your'e not prepared for, and protected from, them.
    I know it's probably too late, but browse over to my web site and read the page 'Attack and Defence'.

    If there is anybody reading this who does NOT have a set of clean disks, as outlined above, DO IT NOW. Run a full virus scan first. And read the page mentioned above.

    Re: How to Make a Boot Floppy

    Hi
    ...now that solution, I like <img src=/S/grin.gif border=0 alt=grin width=15 height=15>.

    I should make sure, if you haven't done so already, that they know about what they've done in no uncertain terms : their carelessness could have infected hundreds of their clients. Heads ought to roll - or at least be caught in a basket.
    Fortunately, for them and anybody else who caught it, this boot-sector virus does not carry a harmful payload and cannot be caught if one adopts clean habits : virus scan strange floppies before using them.

    If you're quite certain your desktop system has not been infected (you never read the floppy in the drive?) you could try making the disks as outlined. Once you've booted your bad system from a clean set the damaged MBR will have been replaced, and hopefully the CMOS restored so your virus scanner will run again. It may get you far enough into your system to clear anything affected. You would not then need to do anything as drastic as reformatting your HD.

    If your'e about to grind down to bare metal, you can try anything that won't cause an explosion. Back up unique data first, of course. If there's anything diseased in there, it won't be affecting your system files, and you can pick it up later. In this particular case, you only have to repair the MBRs of any affected disks, hard or floppy. I'm fairly sure after that your virus scan program will run. If not, re-install it.

    This is what Norton have to say :

    To repair this virus:

    1. Run LiveUpdate to make sure that you have the most recent virus definitions.
    2. Close all programs, shut down the computer, turn off the power, and wait thirty seconds. You must do this to clear memory.
    3. Do one of the following, depending on your version of Norton AntiVirus (NAV):
    NAV 2001. Follow these steps to run the DOS scanner:
    1. Restart the computer using a clean DOS boot disk or a NAV 2001 Emergency Disk that you created on an uninfected computer.
    2. Run Navdx.exe (the DOS scanner):
    If you are using a boot disk, run it from the from the Norton AntiVirus program folder using the /boot and /repair switches. For example:

    C:> progra~1norton~1navdx.exe /cfg:a /boot /repair


    If using the NAV 2001 Emergency Disk, type the following at the Emergency Disk command line:

    navdx.exe /cfg:a /boot /repair

    3. Press Enter and follow the prompts if any.
    NAV 2000 and earlier. Versions of the Emergency Disk program that are included in NAV 2000 and earlier may not be able to remove this virus. You need to download the free, updated version of the DOS scanner. See the document How to create Emergency Disks by downloading a program from the Symantec FTP site.

    After you have created the Emergency Disks on an uninfected computer, follow these steps to run the DOS scanner:
    1. Restart the computer using the Emergency Disk.
    2. At the Emergency Disk command line, type:

    navdx.exe /cfg:a /boot /repair

    3. Press Enter, and follow the prompts.


    In Sympathy
