Antimalware is a scareware program that displays fake scan results, does not allow you to run your normal programs, and hijacks Internet Explorer to display fake security warnings when visiting web sites. When Antimalware is installed on your computer it will be configured to start whenever you run an executable in Windows. Once started, it may automatically open sites such as viagra.com and adult.com. It will then perform a fake scan of your computer and state that there are numerous infections presents. If you try to remove these infections with the program, though, it will state that you first need to purchase it before you will be allowed to do so. As none of the detected files are infected or even exist on your computer, please ignore the results and do not purchase the program.

To protect itself from anti-virus programs and to make you think your computer is seriously infected, Antimalware will also terminate any application you try to run on your computer. When this infection terminates a program it will display a message similar to the following:

Virus Alert!
Application can't be started.
The file notepad.exe is damaged.
Do you want to activate your antivirus software now?

While running, this virus will display numerous security alerts and warnings that are designed to scare you into thinking your computer is infected. One of these alerts include:

Antimalware Alert
Infiltration Alert

Your computer is be attacked by an internet virus. It could be password-stealing attack, a trojan-dropper or similar.

Finally, Antimalware will display a security warning when you browse harmless web sites in Internet Explorer. This warning will state that the site you are visiting is unsafe and that you should purchase Antimalware to protect yourself. The text of this alert is:

Internet Explorer Warning - Visiting this web site may harm your computer!

Most likely causes:

  • The website contains exploits that can launch a malicious code on your computer.
  • Suspicious network activity detected
  • There might be an active spyware running on your compute

Just like the scan results, these fake warnings can safely be ignored.

As you can see, Antimalware was created for the sole purpose of scaring you into purchasing the program by making you think your computer is infected. It goes without saying that you should definitely not purchase this program, and if you already have, please contact your credit card company and dispute the charges stating that the program is a scam and a computer virus.

Automated Removal Instructions for Antimalware using Malwarebytes Anti-Malware:

 

  1. Print out these instructions as we will need to close every window that is open later in the fix.

  2. Reboot your computer into Safe Mode with Networking. To do this, turn your computer off and then back on and immediately when you see anything on the screen, start tapping the F8 key on your keyboard. Eventually you will be brought to a menu similar to the one below:


    MalwareBytes Anti-Malware Screen

    Using the arrow keys on your keyboard, select Safe Mode with Networking and press Enter on your keyboard. If you are having trouble entering safe mode, then please use the following tutorial: How to start Windows in Safe Mode

    Windows will now boot into safe mode with networking and prompt you to login as a user. Please login as the same user you were previously logged in with in the normal Windows mode. Then proceed with the rest of the steps.

  3. Now we must first end the processes that belong to Antimalware and clean up some Registry settings so they do not interfere with the cleaning procedure. To do this, please download RKill to your desktop from the following link.

    RKill Download Link - (Download page will open in a new tab or browser window.)

    When at the download page, scroll down and click on the click on the link labeled explorer.exe download link. When you are prompted where to save it, please save it on your desktop.

  4. Once it is downloaded, double-click on the explorer.exe icon in order to automatically attempt to stop any processes associated with Antimalware and other Rogue programs. Please be patient while the program looks for various malware programs and ends them. When it has finished, the black window will automatically close and you can continue with the next step. If you get a message that RKill is an infection, do not be concerned. This message is just a fake warning given by Antimalware when it terminates programs that may potentially remove it. If you run into these infections warnings that close RKill, a trick is to leave the warning on the screen and then run RKill again. By not closing the warning, this typically will allow you to bypass the malware trying to protect itself so that rkill can terminate Antimalware . So, please try running RKill until the malware is no longer running. You will then be able to proceed with the rest of the guide. If you continue having problems running RKill, you can download the other renamed versions of RKill from the rkill download page. All of the files are renamed copies of RKill, which you can try instead. Please note that the download page will open in a new browser window or tab.

    Do not reboot your computer after running RKill as the malware programs will start again.

  5. Download Malwarebytes Anti-Malware, or MBAM, from the following location and save it to your desktop:

    Malwarebytes Anti-Malware Download Link (Download page will open in a new window)

  6. Once downloaded, close all programs and Windows on your computer, including this one.

  7. Double-click on the icon on your desktop named mbam-setup.exe. This will start the installation of MBAM onto your computer.

  8. When the installation begins, keep following the prompts in order to continue with the installation process. Do not make any changes to default settings and when the program has finished installing, make sure you leave both the Update Malwarebytes Anti-Malware and Launch Malwarebytes Anti-Malware checked. Then click on the Finish button.

  9. MBAM will now automatically start and you will see a message stating that you should update the program before performing a scan. As MBAM will automatically update itself after the install, you can press the OK button to close that box and you will now be at the main program as shown below.

  10. On the Scanner tab, make sure the the Perform full scan option is selected and then click on the Scan button to start scanning your computer for Antimalware related files.

  11. MBAM will now start scanning your computer for malware. This process can take quite a while, so we suggest you go and do something else and periodically check on the status of the scan. When MBAM is scanning it will look like the image below.


    MalwareBytes Anti-Malware Scanning Screen

  12. When the scan is finished a message box will appear as shown in the image below.


    MalwareBytes Anti-Malware Scan Finished Screen

    You should click on the OK button to close the message box and continue with the Antimalware removal process.

  13. You will now be back at the main Scanner screen. At this point you should click on the Show Results button.

  14. A screen displaying all the malware that the program found will be shown as seen in the image below. Please note that the infections found may be different than what is shown in the image.


    MalwareBytes Scan Results


    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.

  15. 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.

  16. You can now exit the MBAM program.

  17. As many rogues and other malware are installed through vulnerabilities found in out-dated and insecure programs, it is strongly suggested that you use Secunia PSI to scan for vulnerable programs on your computer. A tutorial on how to use Secunia PSI to scan for vulnerable programs can be found here:

    How to detect vulnerable and out-dated programs using Secunia Personal Software Inspector

Your computer should now be free of the Antimalware 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.
