PCoptimizer 2010 is a rogue security program that pretends to analyze your computer for virus infections and system errors. When installed, PCoptimizer 2010 will issue an alert that states that one of your running processes is a security issue and will then prompt you to clean your computer. Regardless of what you press on the alert you will be brought to a screen where PrivacyGuard will pretend to scan your computer for viruses and other system errors. When finished it will state that it has fixed these errors and viruses, but that there are other issues it could not fix until you license, or purchase, the program. This is obviously a scam and you should not purchase the program regardless of what it tells you.

PCoptimizer 2010 will also randomly terminate programs when you attempt to run them. When it terminates a program you will be shown an alert that states that the program is trying to perform some sort of malicious activity. The text of these alerts include:

Security alert
Name: taskmgr.exe
Location: C:\WINDOWS\System32
Attempt to modify register key entries is detected. Register entries analysis is recommended.
Deny or Enable Protection.

Security alert
Name: taskmgr.exe
Location: C:\WINDOWS\System32
Potentially harmful script execution is detected. It is strongly recommended to run total System scanning.
Deny or Enable Protection.

Regardless of the button you press, you will be brought to the main PCoptimizer 2010 screen where it will prompt you to purchase a license of the program.

Without a doubt, PC optimizer 2010 was created to display fake security alerts in order to scare you into purchasing the program. It goes without saying that you should definitely not purchase this program, and if you have, you should contact your credit card company and dispute the charges stating that the purchase was actually a computer infection and a scam. To remove this infection and related malware, please follow the steps in the guide below.

Automated Removal Instructions for PCoptimizer 2010 using Malwarebytes Anti-Malware:

  1. Below are the steps to remove PCoptimizer 2010. BleepingComputer has always prided itself on its trusted online support. We are excited to recommend Online Virus Repair Inc. for the same trusted support via telephone. If you are having trouble with the below steps or if you would prefer to speak to someone over the phone, you can contact Online Virus Repair at the below number.

    Premium Phone Support
    Otherwise, as always you can always ask us for further help in the forums.

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

  3. It is possible that the infection you are trying to remove will not allow you to download files on the infected computer. If this is the case, then you will need to download the files requested in this guide on another computer and then transfer them to the infected computer. You can transfer the files via a CD/DVD, external drive, or USB flash drive.

  4. Before we can do anything we must first end the processes that belong to PCoptimizer 2010 so that it does 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, click on the Download Now button labeled iExplore.exe download link. When you are prompted where to save it, please save it on your desktop.

  5. Once it is downloaded, double-click on the iExplore.exe icon in order to automatically attempt to stop any processes associated with PCoptimizer 2010 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 PCoptimizer 2010 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 PCoptimizer 2010 . 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.

  6. At this point you should download Malwarebytes Anti-Malware, or MBAM, to scan your computer for any any infections or adware that may be present. Please download Malwarebytes from the following location and save it to your desktop:

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

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

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

  9. 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 Launch Malwarebytes Anti-Malware checked. Then click on the Finish button. If MalwareBytes prompts you to reboot, please do not do so.

  10. MBAM will now start and you will be at the main screen as shown below.

    Malwarebytes Anti-Malware

    Please click on the Scan Now button to start the scan. If there is an update available for Malwarebytes it will automatically download and install it before performing the scan.

  11. MBAM will now start scanning your computer for malware. This process can take quite a while, so we suggest you do something else and periodically check on the status of the scan to see when it is finished.

    Malwarebytes Anti-Malware

  12. When MBAM is finished scanning it will display a screen that displays any malware that it has detected. Please note that the infections found may be different than what is shown in the image below due to the guide being updated for newer versions of MBAM.

    MalwareBytes Scan Results

    You should now click on the Remove Selected button to remove all the seleted 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.

  13. You can now exit the MBAM program.

  14. 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:

Your computer should now be free of the PCoptimizer2010 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.
