80000064.@ Trojan detected


Avast found a Trojan on my brother's laptop and placed it inside it's chest. But he can't delete them.

He's tried a system restore point and the computer restarted saying that it was unsuccessful as the Windows/Installer file was inaccessible (this was one of the files that was infected)

Tried system image recovery - disk with files on isn't being recognised

Tried re-installing windows and it says no valid windows installation detected

Been trying to solve this for nearly a week.

Any advice would be very much appreciated.

  1. If you have Avast! try the boot-time scan.

    - Open main Window
    - Click Scan Computer
    - Click Boot-time Scan
    - Click Schedule Now
    - Restart the computer.

    This allows it to scan before Windows has loaded thus system files are not in use (ie. it can heal/delete them if necessary)
  2. I'm afraid that's already been tried and the problem has not been fixed.
    Avast was unable to repair or delete the infected file.
    Thanks for the suggestion.
  3. that is a rootkit, alueron or zeroaccess... can you reload?

    Removal is very tough.
  4. Tried R-Kill initially then conducted boot time scan with Avast.

    Haven't tried Malwarebytes yet though. That was gonna be the next step but I wanted to see if any other suggestions would appear first.

    So you suggest going ahead with R-Kill followed by Malwarebytes?
  5. Kaspersky has there rescue CD's you could download and use to try cleaning the system.
