What is Antimalware Doctor?

The Malwarebytes research team has determined that Antimalware Doctor is a fake anti-malware application. These so-called "rogues" use intentional false positives to convince users that their systems have been compromised. Then they try to sell you their software, claiming it will remove these threats. In extreme cases the false threats are actually the very trojans that advertise or even directly install the rogue. You are strongly advised to follow our removal instructions below.

How do I know if I am infected with Antimalware Doctor?

This is how the main screen of the rogue application looks:

How did Antimalware Doctor get on my computer?

Rogue programs use different methods for spreading themselves. This particular one was spread using an exploit on an infected site.

How do I remove Antimalware Doctor?

Our program Malwarebytes' Anti-Malware can detect and remove this rogue application.
  • Please download Malwarebytes' Anti-Malware to your desktop.

  • Then click Finish.
  • If an update is found, it will download and install the latest version.
  • Once the program has loaded, select Perform quick scan, then click Scan.
  • When the scan is complete, click OK, then Show Results to view the results.
  • Be sure that everything is checked, and click Remove Selected. Reboot your computer if prompted.
  • When completed, a log will open in Notepad. The rogue application should now be gone.

Is there anything else I need to do to get rid of Antimalware Doctor?

  • No, Malwarebytes' Anti-Malware removes Antimalware Doctor completely.

How would the full version of Malwarebytes' Anti-Malware help protect me?

We hope our application has helped you eradicate this malicious software. If your current security solution let this infection through, you might please consider purchasing the FULL version of Malwarebytes' Anti-Malware for additional protection.

Still a leftover I'm afraid. Probably uninstalled or removed incomplete.
Should be easy to fix, if you post your logs in a new thread here:

Not here Steve. In the appropriate forum.

And I think the OTL log would be more helpful in a case like this.

Please go to the malware forum and follow the instructions at the top....Especially the CLICK HERE.

That will give you several steps that will help you clean up 70 percent of all problems by yourself. If at the end of the process you are still having difficulty--and you may not be-- then post an OTListIt log in THAT forum.
