[A] AVG threat detected: Trojan horse Crypt.AQLW, system crashing

  1. Hi guys,

    This is my first post here and I would really appreciate your assistance.

    I'm running Windows 7 on a Dell Latitude E6400 with AVG Internet Security 2012. AVG has today identified 'Threat Detected' alerts stating threat name "Trojan Horse Crypt.AQLW" and "win32/Sirefref.ER".

    They appear "C:\windows\system32\(different letters each time).dll". I have moved them to the Quarantine Vault with no success. I have run Malwarebytes and Spybot S&D which identified and removed some items. However, the computer is still not responding and keeps identifying the same threat.

    I can no longer access anything on my computer in normal mode as it keeps crashing but I can start safe mode.

    I really do appreciate your assistance and look forward to your advice.
