FakeAlert!PCVirusless trojan or virus

How serious is this Trojan?…how can it be removed without harming the System32\at171.dll? Thanks! Can I do it with the Super AntiSpyware Free Edition 4.48.1000? Should I just rebuild the dll with RestoreGuard At171.dll Repair tool?

    I have the exact same virus and received the exact same response using Stinger.

    I’ve run the latest version of Stinger on 5 machines today all of them came up with this virus. One of the machines was a new install and so I am of the opinion this is a false positive. Very rare for Stinger but even the best scanners blow it sometime. If the McAfee guys want to prove me wrong I’ll be happy to listen but for now I’m just ignoring this message.

    McAfee checked my machine remotely and said that there was “no virus or Trojan”. However, everytime I use my att.yahoo email account I get re-directs to fake websites that tell me my computer is infected, or want me to answer a questionnaire. Anyone have any ideas about what is going on?
    My McAfee AntiVirus still comes up with (1) Trojan everytime it scans….

    Try Malwarebytes found at malwarebytes.org. Hopefully that will do it. I still think Stinger is not working properly at the moment. Good luck hopefully someone smarter than myself can help.

    I ran the free version of Malwarebytes and it did not find the trojan mentioned above, nor did it fix the problem.

    This issue has been fixed . Please check stinger again!.

    I bought Webroot and it cleaned up my (2) trojans and (1) malware. The actual name was not the FakeAlert!PCvirusless mentioned above, but completely different names.
