System Care Antivirus is a computer infection from the Rogue.WinWebSec family of rogue anti-spyware programs. This program is categorized as a rogue because it pretends to be an anti-virus program, but instead displays fake scan results, fake security alerts, and blocks you from running your normal applications. This program is distributed through hacked web sites that exploit vulnerabilities on your computer and as Trojans disguised as a program that is necessary to view an online video. This particular variant is also known to be installed with the ZeroAccess rootkit, which makes it harder to remove and clean your computer.
Once installed, System Care Antivirus will be configured to start when you login to Windows. Once started, it will perform a fake scan of your computer that will state that numerous infections are present. If you try to clean these infections, though, System Care Antivirus will state that you first need to purchase the program before being able to do so. As all of the scan results displayed by this program are fake, please ignore any prompts to purchase the program.

Guide Updates:
04/09/13 - Initial guide creation.
- Print out these instructions as we may need to close every window that is open later in the fix.
- 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: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 ModeWindows will now boot into safe mode with networking and prompt you to login as a user.

- 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.
- Before we can do anything we must first end the processes that belong to System Care Antivirus 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.
- Once it is downloaded, double-click on the iExplore.exe icon in order to automatically attempt to stop any processes associated with System Care Antivirus 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 System Care Antivirus 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 System Care Antivirus . 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. Do not reboot your computer after running RKill as the malware programs will start again.If you continue having problems running RKill, you can download the other renamed versions of RKill from the RKill download page. Both of these 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.
- Now you should 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)

- Double-click on the icon on your desktop named mbam-setup.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 both the Update Malwarebytes Anti-Malware and 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 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.
- 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 System Care Antivirus related files.

Please note that the infections found may be different than what is shown in the image.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.
- 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.
- You can now exit the MBAM program.
- 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.
