What is Internet Antivirus Pro?

The Malwarebytes research team has determined that Internet Antivirus Pro 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 Internet Antivirus Pro?

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

How did Internet Antivirus Pro get on my computer?

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

How do I remove Internet Antivirus Pro?

Our program Malwarebytes' Anti-Malware can detect and remove this rogue application.
  • Please download Malwarebytes' Anti-Malware to your desktop.
  • Double-click mbam-setup.exe and follow the prompts to install the program.
  • At the end, be sure a check-mark is placed next to the following:

    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • 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 Internet Antivirus Pro?
  • The rogue intercepts calls to your task manager. You can download Process Explorer. Run it and click "Options" > "Replace Task Manager". Enjoy the added value that Process Explorer has over your standard Task Manager.

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 Internet Antivirus Pro rogue. It would have warned you before the rogue could install itself, giving you a chance to stop it before it became too late.
