How to remove ExpertAntivirus (Removal Instructions)

What this programs does: ExpertAntvirus, is a rogue anti-spyware program which displays fake and exaggerated scan results. When this program is installed on a computer it creates fake Windows Registry keys and fake files that are completely safe, but are reported by the program as malware. In this way, you can have a completely clean computer, yet the program will still find these files and Windows Registry entries and declare them to be malware related. In order to remove these fake infections you are prompted to purchase the commercial version of this software. Needless to say, you should not fall for this scam and purchase it. The guide below will walk you through the removal of the program and the fake malware files and entries it creates.

  7. Download FixEA.reg to your desktop by right clicking on the following link and then selecting Save Link As or Save File as, depending on your browser.

    FixEA.reg Download Link

    Confirm that the file FixEA.reg now resides on your desktop as we will need it later.

  8. Go to your desktop and double click on the FixEA.reg file that you downloaded earlier. When it asks if you would like to merge the information, press the Yes button and then the OK button.

  9. Click on the Start button and then select the Run option.

  10. Delete the following files and folders (Do not be concerned if a folder does not exist):

  11. Close all open Windows.

  12. We next perform an online scan with Panda to find any possible inactive remnants from this infection: Panda Online

    1. Once you are on the Panda site click the Scan your PC button

    2. A new window will open and you should click the Check Now button

    3. Enter your Country

    4. Enter your State/Province

    5. Enter your e-mail address and click send

    6. Select either Home User or Company

    7. Click the big Scan Now button

    8. If it wants to install an ActiveX component allow it

    9. It will start downloading the files it requires for the scan (Note: It may take a few minutes)

    10. When download is complete, click on Local Disks to start the scan
