    Hello,
    My brother and I share a laptop computer and my brother has recently downloaded quite a few games. MSE detected threats called sirefef, at first MSE removed them but different variants shown back up almost immediately. After a few tries of this the computer starts to display a emergency shutdown 1 min then reboots. I've read the guidelines and cant complete any of the (RougeKiller, Malwarebytes, Hitman Pro, and MG tools) because of the 1 min reboot. I also have DEAMON tools but because of the 1 min reboot im haveing trouble disableing it in normal and safe mode.
    Help greatly appreciated ~ Keenan​

    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.
    • Use the arrow keys to select the Repair your computer menu item.
    • Select US as the keyboard language settings, and then click Next.

    • 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.
    • Select the operating system you want to repair, and then click Next.

    • The notepad opens. Under File menu select Open.

    • 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)

    Please download ComboFix to your desktop and run it. Do not do anything while it runs. Attach the log when it is finished.
