Today i had the pleasure of removing this infection from a computer. As a rule i remove these types of infections using instructions from the www.bleepingcomputer.com website.
This removal guide is provided by them on their website here….
What this infection does:
My Security Shield is a rogue anti-spyware program from the same family as Virus Doctor. This infection is promoted through web sites that show advertisements that pretend to be online anti-malware scanners. These scanners will then pretend to scan your computer, and when finished, will state that your computer is infected and that you need to download and install My Security Shield to protect yourself. The truth is that these online scanners are all fake and are only an advertisement. They have no way of knowing what is running on your computer.
Once My Security Shield is installed on your computer it will be configured to start automatically. It will also create numerous files that will be detected by the program as malware. Some of the files that are created are:
When the program scans your computer it will detect the files it created and state that they are infections. It will then prompt you to remove the files, but will not allow you to do so until you first purchase the program. This is a scam as the files are all harmless and are created by the My Security Shield program in the first place. Therefore, please ignore any of the scan results this program displays.
While My Security Shield is running it will also display fake security warnings that are designed to make you think that your computer has a severe computer security problem. The text of some of the alerts you will see are:
Warning! Access conflict detected!
An unidentified program is trying to access system process address space.
Process Name: AllowedForm
Warning! Identity theft attempt detected
Memory access problem
WindowsErrorForm has encountered a problem at address 0x1FC408.
We are sorry for the inconvenience.
If you see this error again, operational information can be irrevocably lost.
Warning! Virus detected
Threat Detected: Trojan-PSW.VBS.Half
Description: This is a VBScript-virus. It steals user’s passwords.
As all of these security alerts are fake, they should be ignored.
As you can see, My Security Shield is a scam and was only created to trick you into purchasing it. You should not purchase it, and if you have, you should contact your credit card company and dispute the charge. To remove My Security Shield and any related malware, please follow the steps in the removal guide below.
Automated Removal Instructions for My Security Shield using Malwarebytes’ Anti-Malware:
1. Print out these instructions as we may need to close every window that is open later in the fix.
2. 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.
3. Before we can do anything we must first end the processes that belong to My Security Shield so that it does not interfere with the cleaning procedure. To do this, download the following file to your desktop.
4. Once it is downloaded, double-click on the rkill.com in order to automatically attempt to stop any processes associated with My Security Shield 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 My Security Shield 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 My Security Shield . 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.com, you can download iExplore.exe or eXplorer.exe, which are renamed copies of rkill.com, and try them instead.
Do not reboot your computer after running rkill as the malware programs will start again.
5. 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)
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. If MalwareBytes’ prompts you to reboot, please do not do so.
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 My Security Shield 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.
12. When the scan is finished a message box will appear as shown in the image below.
You should click on the OK button to close the message box and continue with the My Security Shield 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.
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 this infection also changes your Windows HOSTS file, we want to replace this file with the default version for your operating system. Please note that if you or your company has added custom entries to your HOSTS file then you will need to add them again after restoring the default HOSTS file. In order to protect itself, My Security Shield changes the permissions of the HOSTS file so you can’t edit or delete it. To fix these permissions please download the following batch file and save it to your desktop:
When the file has finished downloading, double-click on the hostsperm.bat file that is now on your desktop. If Windows asks if you if you are sure you want to run it, please allow it to run. Once it starts you will see a small black window that opens and then quickly goes away. This is normal and is nothing to be worried about. You should now be able to access your HOSTS file.
18. We now need to delete the C:\Windows\System32\Drivers\etc\HOSTS file. Once it is deleted, download the following HOSTS file that corresponds to your version of Windows and save it in the C:\Windows\System32\Drivers\etc folder. If the contents of the HOSTS file opens in your browser when you click on a link below then right-click on the appropriate link and select Save Target As…, if in Internet Explorer, or Save Link As.., if in Firefox, to download the file.
Your Windows HOSTS file should now be back to the default one from when Windows was first installed.
19. Now reboot your computer.
20. 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 My Security Shield 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.
