Internet Antivirus Pro is a new rogue anti-virus program that uses false information and aggressive tactics in order to scare people into purchasing it. Most people see ads for Internet Antivirus Pro as they browse the web. Certain sites will display a pop-up ad stating that your computer has infections, even though the web site has no way of knowing that, and then pretends to be a program scanning your computer for malware. Once this ad has finished with its act you will see another popup stating that a variety of infections were found and that you should download and install Internet Antivirus Pro.

If you decide to download and install the program, Internet Antivirus Pro will be set to automatically run when your computer starts. Once started, it will scan your computer and display a variety of legitimate programs and folders and state that they are infection. These infections, though, can't be removed unless you first register the program. This act of displaying legitimate entries as malware is being done to scare you into purchasing the program. In fact, if you deleted all of the files and folders that it stated were infections, your computer would not run properly.

Another side effect of this program is that it will inject fake warnings into the web sites you visit, display fake warnings when you browse to various web sites, and issue popups stating that your computer has a variety security risks. These popups and warnings can cause your computer to slow down and not run as efficiently as it should.

    You should now click on the Remove Selected button to remove all the listed malware. MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so. Once your computer has rebooted, and you are logged in, please continue with the rest of the steps.
    
    
12. When MBAM has finished removing the malware, it will open the scan log and display it in Notepad. Review the log as desired, and then close the Notepad window.
    
    
13. You can now exit the MBAM program.
    

Your computer should now be free of the InternetAntivirus Pro program. If your current anti-virus solution let this infection through, you may want to consider purchasing the PRO version of Malwarebytes' Anti-Malware to protect against these types of threats in the future.
