I was recently hit by a variant of Trojan.FakeAlert. It did a whole lot of things: it disabled the Security Center, it installed a proxy that limited access to the web, it kept generating annoying popups. However, the most annoying thing it did was associate all .exe files with itself. This meant that I could not run the task manager to stop the process, nor could I run regedit to restore the correct associations. I also could not get to this site, or to any anti-virus web site. I could not even find a copy of rkill.com that I could download from the Internet. I got it fixed by renaming system files and restarting my computer several times, but it was a huge, time-consuming hassle.

What would be wonderful is if there were a way to create a bootable CD that had just the necessary files to run MalwareBytes and to edit the registry. I started to fool around with this, but MalwareBytes needs to be installed (it won't run standalone), and although I could get regedit to open, it was looking at the copy of the registry from the boot CD and not the registry that was actually on the hard drive. Is there a CD that will boot up (to either XP or Linux), allow me to scan a Windows partition for malware (with MalwareBytes or a program that is as useful as MalwareBytes), and edit the infected Windows registry? If not, would anyone be interested in working with me to create such a CD? I think it would save a lot of people a lot of time to have a clean boot option with useful tools pre-installed.

Is this something like what you are looking for? Using Ultimate Boot CD for Windows® to Rescue Files from a Computer that will not Boot Correctly

Sort of, I guess. What I am really looking for is what used to be available until Windows 98 came out. THat is, my Norton Utilities program would create a bootable disk, with itself installed on it. If a virus hit my computer that prevented it from booting up for functioning properly, I could insert my bootable disk. It would boot up, Norton would run, it would fix the problem on the hard drive, and then I would restart the computer and everything would (usually) be back to normal.

I could rescue files simply by booting to a bootable linux CD, mounting the Windows partition, and copying the files I wanted to save. That seems to be all the Utlimate Boot CD does.

BartPE Bootable CD does all that. You can add plugins and edit registry.

I guess we shall have to make a plugin for MBAM too :thumbsup:

These are links to Anti-virus vendors that offer free LiveCD or Rescue CD utilities that are used to boot from for repair of unbootable and damaged systems, rescue data, scan the system for virus infections. Burn it as an image to a CD disk to get a bootable CD. All (except Avira) are in the ISO Image file format. Avira uses an EXE that has built-in CD burning capability.If you are not sure how to burn an image, please read How to write a CD/DVD image or ISO. If you need a FREE utility to burn the ISO image, download and use ImgBurn.

-- Note: In order to use a rescue disk, the boot order must be set to start from the CD-ROM drive. If the CD is not first in the boot order, the computer will attempt to start normally by booting from the hard drive. The boot order is a setting found in the computer’s BIOS which runs when it is first powered on. This setting controls the order that the BIOS uses to look for a boot device from which to load the operating system. The default will normally be A:, C:, CD-ROM. Different computers have different ways to enter the BIOS. If you're not sure how to do this, refer to:

Doesn't SARDU do all this too? I was looking at it trying to be proactive for future malware battles and it lets you add a bunch of utilities to it. There's a link to it from Gizmo's "Probably the Best Free Security List..." you can also pull numerous utilities from this list to add to the disk.

Another thought is to boot from a Linux distro to gain unrestricted access to Windows folders and registry,
where you can restore your registry from backup and run MBam using Wine. There's a tutorial on this at Windows7Forums.
If you can't find it let me know, I have it bookmarked on my home computer.
