    Hello, any help would be appreciated. I was downloading something only to realize later that people said some files were infected with BackDoor-AWQ.b!efs. Now my computer wont start, it goes into repair mode and is not able to repair. I have tried booting in safe mode but it still goes to the blue screen trying to repair the computer and is unable to.

    I have 2 hard drives and my 64-bit OS and programs are installed on my SSD and most of my files are on my regular HD. I have tried making a Kaspersky USB rescue disc 10, but when I try to boot from it on my infected pc I get a "invalid or damaged bootable partition" error. I did go into my BIOS and changed the boot priority to cdrom/usb like the instructions asked. I made the rescue disc on my older 32-bit laptop so I'm not sure if thats an issue. I didn't see any Kaspersky iso's differentiating b/w the two so I assumed it would work for both.

    Any advice on what I should do? Thanks

    Just an update, I created the same Kaspersky rescue usb on my friends 64-bit windows 7 and still got the "invalid/damaged partition" error. I also tried copying the iso onto a cd and tried to boot from there since the boot order said "usb cdrom" but that didn't work either.

    Please do the below so that we can boot to System Recovery Options to run a scan. There will be two options to choose from. One if you do not have your Windows 7 boot DVD and another when you have your DVD.

    For x32 (x86) bit systems download Farbar Recovery Scan Tool and save it to a flash drive.
    For x64 bit systems download Farbar Recovery Scan Tool x64 and save it to a flash drive.

    Plug the flashdrive into the infected PC.

    Option1: Enter System Recovery Options from the Advanced Boot Options:

    • Restart the computer.
    • As soon as the BIOS is loaded begin tapping the F8 key until Advanced Boot Options appears.

    • If prompted, press any key to start Windows from the installation disc. If your computer is not configured to start from a CD or DVD, check your BIOS settings.
    • Click Repair your computer.
    • Select US as the keyboard language settings, and then click Next.

    • In the command window type e:\frst.exe (for x64 bit version type e:\frst64) and press Enter
      Note: Replace letter e with the drive letter of your flash drive.
    • The tool will start to run.
    • When the tool opens click Yes to disclaimer.
    • Press Scan button.
    • It will make a log (FRST.txt) on the flash drive. Please attach this file to your next reply. (See: How to attach)

    I am not finding any malware in your log. I suggest you post in the software forum to try to get your system to boot. Then you can return here to continue with any malware that may not have shown up in that log.
