Windows XP boots up normally then goes to grey screen

by akdilger / October 26, 2009 12:20 AM PDT

Yesterday, I contracted a virus, which showed up as msb.exe in my task manager. It installed a bunch of fake anti-virus software. I restarted the computer to try to remove it in safe mode, and after the computer booted (went throgh normal welcome screen and everything) the screen is just grey. I'm sure it's not a video card or anything because the graphics that do come up are fine.
On top this, I can not boot into safe mode either. The menu at F8 gives the option but then it does not boot up and returns me to the same screen. I can't use msconfig, because I can't get to my desktop, just the blank grey screen.

Any tips? I don't want to lose all the data on my computer, otherwise I would have re-installed XP by now.

Because It's Malware..
by Grif Thomas Forum moderator / October 26, 2009 9:50 AM PDT

Please follow the instructions below:

On a friend or family member's computer, download the Malwarebytes installer and update files from the links below, copy them to a CD or flash drive, then transfer the files to the problem machine and use them. If you can't start the computer into "normal" windows, try installing, updating, and running the scans AFTER the computer is started into Safe Mode.. I use the sites below to download the installer file and the manual updater:

Once downloaded and before transferring them to the problem machine, rename the program installer "mbam-setup.exe" file to something else like "Gogetum.exe", then copy the installer file and the update file to a CD or flash drive.. Transfer the file to the problem machine, then install the "Gogetum.exe" file, then run the update to get the program current.. After that, run a full system scan and delete anything it finds.

Malwarebytes Installer Download Link (Clicking on the links below will immediately start the download dialogue window.)
http://www.besttechie.net/tools/mbam-setup.exe

Malwarebytes Manual Updater link
http://www.malwarebytes.org/mbam/database/mbam-rules.exe

Next, download the SuperAntispyware program and the manual updater from the links below. After running the Malwarebytes tool above, if you still can't download and install it directly from the problem machine, download it on a friend or family member's computer as well. After installing and updating SuperAntispyware, run another full system scan and delete everything it finds as well. As before, you may need to rename the installer file to get the program to install.:

SuperAntispyware Manual Updater

____________

In a few situations, in order for the program to run, it was also necessary to rename the main "mbam.exe" file also after installing it.. It resides in the C:\Programs Files\Malwarebytes Antimalware folder....

Hope this helps.

That all requires me to be able to boot into safe mode, which I cannot do. It says it cannot get into safe mode and tells me to choose another option. None of them work either...

Then Don't Do It In Safe Mode..
by Grif Thomas Forum moderator / October 26, 2009 10:19 AM PDT

The key issue is to download the installer and updater files on a separate computer, then transfer them to the problem machine, install the program, update it, then run it.. If it only runs in "normal" Windows, do it.

Hope this helps.

With nothing but a grey screen, I'm not sure how to install and/or run anything.

Ahhhh.. A Clearer Explanation Would Have Helped...
by Grif Thomas Forum moderator / October 26, 2009 2:47 PM PDT

Unfortunately, you didn't indicate you couldn't run anything in normal Windows.. You only said you had a grey screen.

So...if you can't run anything in either Safe Mode or "normal" Windows, there are few options left.. So, to try a different fix, you'll need the help of a separate clean computer.. On the clean computer, click on the link below and create the Secured2K boot disc mentioned.. You'll then use the boot disc to start the computer with, then scan the computer outside of Windows and then run other scanning tools afterward. Read a few of the posts in the thread, (it's a McAfee forum) and follow the procedures mentioned by Secured2k..

Secured2k BootCD - Malware/Rootkit Removal

If you can't fix your issue, or at least get to the computer to boot into some sort of Windows, you'll have no other choice than to format the computer and reinstall the operating system, drivers, and all other software back to factory condition..

Hope this helps.
