What is Wolfram Antivirus?

The Malwarebytes research team has determined that Wolfram Antivirus 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 Wolfram Antivirus?

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

How did Wolfram Antivirus get on my computer?

Rogue programs use different methods for spreading themselves. This particular one was installed by a trojan.

How do I remove Wolfram Antivirus?

Our program Malwarebytes' Anti-Malware can detect and remove this rogue application.
  • Please download Malwarebytes' Anti-Malware from here
    If you are unable to do this from the infected computer directly, transfer the file from another computer.
  • Download the mbam-setup.exe to your desktop.
  • Now make sure extensions are shown. To do this, please look here
  • Then rename the mbam-setup.exe: Posted Image to iexplore.exe
  • Then launch iexplore.exe in order to install Malwarebytes' Anti-malware
  • Once Malwarebytes' Anti-Malware is installed, navigate to your Program Files\Malwarebytes' Anti-Malware folder and locate the mbam.exe in there:

  • Click the "Update" tab and click the "Check For updates" button.
  • Once the program has loaded and updates were downloaded, select "Perform Quick Scan", then click Scan.
  • The scan may take some time to finish,so please be patient.
  • When the scan is complete, click OK, then Show Results to view the results.
  • Make sure that everything is checked, and click Remove Selected.
  • When disinfection is completed, a log will open in Notepad and you may be prompted to Restart, so please allow MBAM to restart.
  • The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.

Is there anything else I need to do to get rid of Wolfram Antivirus?

  • No, Malwarebytes' Anti-Malware removes Wolfram Antivirus 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.

As you can see below the full version of Malwarebytes' Anti-Malware would have protected you against the Wolfram Antivirus rogue. It would have warned you before the rogue could install itself, giving you a chance to stop it before it became too late.
