Extra Antivirus is a rogue anti-spyware program from the same family as Virus Sweeper. Coincidentally, S!RI reports that another rogue with the same name was released at the same time that belongs to the family of rogues that include MS AntiSpyware 2009 and P Antispyware 09. Though this guide will remove both versions of Extra Antivirus, we will focus on the Virus Sweeper clone for the rest of this guide. I have, though, included images of both variants of Extra Antivirus in the screen shots below.
The virus sweeper family of rogues has the unique characteristic of using a legitimate service as a way of distributing its files. This service is Google Code, which is a repository for programmers to store their programming source code and projects. When the Trojan is executed it will first connect to Google Code in order to try and download the entire Extra Antivirus program. If these files are not available it will then try to install the program via other servers under the malware developer's control.
When the program is installed it will be set to automatically start on your computer. The installer then create numerous files that are used impersonate infections. These files, though, are harmless and cannot even be executed. Therefore, they pose no risk to your computer. The list of fake infections that are created on your computer are:
When the program executes it will scan your computer and display the files listed above and state they are infections, but will not remove them until you purchase the program. While the program is running you will also see nag screens or security warnings appear on your desktop. These screens will pop-up over your existing applications and will not go away until you acknowledge them. These warnings are a further attempt by Extra Antivirus to convince you that you are infected. The text of one of these alerts is:
malicious applications, which can contain trojans, were found on your PC and need to be immediately removed. Click here to remove these potentially harmful items using Extra Antivirus.
If you are infected with Extra Antivirus, please do not purchase the program. Instead use the free removal guide below. If you have already purchased this product, we suggest you contact your credit card company to discuss disputing these charges as it is a scam.
Self Help Guide
This removal guide may appear overwhelming due to the amount of the steps and numerous programs that will be used. It was only written this way to provide clear, detailed, and easy to understand instructions that anyone can use to remove this infection for free. Before using this guide, we suggest that you read it once and download all necessary tools to your desktop. After doing so, please print this page as you may need to close your browser window or reboot your computer.
To terminate any programs that may interfere with the removal process we must first download the Rkill program. Rkill will search your computer for active malware infections and attempt to terminate them so that they wont interfere with the removal process. To do this, please download RKill to your desktop from the following link.
When at the download page, click on the Download Now button labeled iExplore.exe. When you are prompted where to save it, please save it on your desktop.
Once it is downloaded, double-click on the iExplore.exe icon in order to automatically attempt to stop any processes associated with Extra Antivirus and other malware. 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 a log file will open. Please review the log file and then close so you can continue with the next step. If you have 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.
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:
Once downloaded, close all programs and Windows on your computer, including this one.
Double-click on the icon on your desktop named mbam-setup-bc.1878-126.96.36.1994.exe. This will start the installation of MBAM onto your computer.
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.
MBAM will now start and you will be at the main screen as shown below.
We now need to enable rootkit scanning to detect the largest amount of malware that is possible with MalwareBytes. To do this, click on the Settings section at the top of the MalwareBytes application and you wil be brought to the general settings section.
Now click on the Detection and Protection settings category on the left sidebar. You will now be shown the settings MalwareBytes will use when scanning your computer.
At this screen, please put a checkmark in the option labaled Scan for rootkits. If you do not see this option, please make sure you are using the latest version of MalwareBytes.
Now that you have enabled rootkit scanning, click on the Scan button to go to the scan screen.
Make sure Threat ScanStart Scan button. If there is an update available for Malwarebytes it will automatically download and install it before performing the scan.
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.
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.
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.
You can now exit the MBAM program.
As many malware and unwanted programs 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:
