What is Win 7 Antispyware 2012 & Vista Antivirus 2012?

Win 7 Antispyware 2012, Vista Antivirus 2012, and XP Security 2012 are all names for the same rogue anti-spyware program. This family of rogues is promoted in two ways. The first is through the use of fake online antivirus scanners that state that your computer is infected and then prompt you to download a file that will install the infection. The other method are hacked web sites that attempt to exploit vulnerabilities in programs that you are running on your computer to install the infection without your knowledge or permission. Regardless of how it is installed, once it is running on your computer it will install itself as a variety of different program names and graphical user interfaces depending on the version of Windows that is running. Regardless of the name, though, they are all ultimately the same program with just a different skin on it. This rogue goes by different program names, which I have listed below based upon the version of Windows that it is installed on:

Windows XP Rogue Name
Windows Vista Rogue Name
Windows 7 Rogue Name
XP Antispyware 2012 Vista Antispyware 2012 Win 7 Antispyware 2012
XP Antivirus 2012 Vista Antivirus 2012 Win 7 Antivirus 2012
XP Security 2012 Vista Security 2012 Win 7 Security 2012
XP Home Security 2012 Vista Home Security 2012 Win 7 Home Security 2012
XP Internet Security 2012 Vista Internet Security 2012 Win 7 Internet Security 2012

When installed, this rogue pretends to be a security update for Windows installed via Automatic Updates. It will then install itself as a single executable that has a random consisting of three characters, such as kdn.exe, that uses very aggressive techniques to make it so that you cannot remove it. First, it makes it so that if you launch any executable it instead launches Vista Home Security 2012, XP Internet Security 2012, Win 7 Security 2012, or any of the other names it goes under. If the original program that you wanted to launch is deemed safe by the rogue, it will then launch it as well. This allows the rogue to determine what executables it wants to allow you to run in order to protect itself. It will also modify certain keys so that when you launch FireFox or Internet Explorer from the Window Start Menu it will launch the rogue instead and display a fake firewall warning stating that the program is infected.

  • Vista Antispyware 2012 Screen shot
  • XP Antispyware 2012 Screen shot
  • Windows 7 Action Center
  • Windows Vista Windows Security Center
  • Windows XP Windows Security Center
  • Security Hole Alert
  • Browser Hijack
  • Fake Firewall Alert
  • Fake Malware Intrusion Alert
  • Fake System Danger Alert

Once started, the rogue itself, like all other rogues, will scan your computer and state that there are numerous infections on it. If you attempt to use the program to remove any of these infections, though, it will state that you need to purchase the program first. In reality, though, the infections that the rogues states are on your computer are all legitimate files that if deleted could cause Windows to not operate correctly. Therefore, please do not manually delete any files based upon the results from this rogue's scan.

While running, XP Internet Security 2012, Win 7 Antivirus 2012, and Vista Security 2012 will also display fake security alerts on the infected computer. The text of some of these alerts are:

XP Home Security 2012 Firewall Alert
XP Home Security 2012 has blocked a program from accessing the internet
Internet Explorer is infected with Trojan-BNK.Win32.Keylogger.gen
Private data can be stolen by third parties, including credit card details and passwords.

XP Antispyware 2012 Alert
Security Hole Detected!
A program is trying to exploit Windows security holes! Passwords and sensitive data may be stolen. Do you want to block this attack?

Just like the scan results, these security warnings and alerts are all fake and should be ignored.

While running, Win 7 Home Security 2012, XP Antivirus 2012, and Vista Antivirus 2012 will also hijack Internet Explorer so that you cannot visit certain sites. It does this so that you cannot receive help or information at sites like on how to remove this infection. When you attempt to visit these sites you will instead be shown a fake alert stating that the site you are visiting is dangerous and that the rogue is blocking it for your protection. The message that you will see is:

Vista Security 2012 Alert
Internet Explorer alert. Visiting this site may pose a security threat to your system!

Possible reasons include:
- Dangerous code found in this site's pages which installed unwanted software into your system.
- Suspicious and potentially unsafe network activity detected.
- Spyware infections in your system
- Complaints from other users about this site.
- Port and system scans performed by the site being visited.

Things you can do:
- Get a copy of Vista Security 2012 to safeguard your PC while surfing the web (RECOMMENDED)
- Run a spyware, virus and malware scan
- Continue surfing without any security measures (DANGEROUS)

Just like the fake security alerts, the browser hijack is just another attempt to make you think that your computer has a security problem so that you will then purchase the program.

Without a doubt, this rogue is designed to scam you out of your money by hijacking your computer and trying to trick you into thinking you are infected. Therefore, please do not purchase this program , and if you have, please contact your credit card company and dispute the charges stating that the program is a computer infection. Finally, to remove Win 7 Antispyware 2012, Vista Antivirus 2012, and XP Security 2012 please use the guide below, which only contains programs that are free to use.

Win 7 Antispyware 2012 & Vista Antivirus 2012 Removal Options

Self Help Guide

This guide is intended for advanced computer users only. Please ensure your data is backed up before proceeding. If you’re uncomfortable making changes to your computer, consider having a professional help clean your computer or ask in the forums.
  1. Print out these instructions as we may 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. 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 Win 7 Antispyware 2012 & Vista Antivirus 2012 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 When you are prompted where to save it, please save it on your desktop.

  5. Once it is downloaded, double-click on the icon in order to automatically attempt to stop any processes associated with Win 7 Antispyware 2012 & Vista Antivirus 2012 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 Win 7 Antispyware 2012 & Vista Antivirus 2012 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 Win 7 Antispyware 2012 & Vista Antivirus 2012 . 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. All 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.

  6. As this infection is known to be bundled with the TDSS/Necurs rootkit infection, you should also run a program that can be used to scan for this infection. Please follow the steps in the following guide:
    How to remove Google Redirects or the TDSS, TDL3, or Alureon rootkit using TDSSKiller
    If after running TDSSKiller, you are unable to update Malwarebytes' Anti-malware or continue to have Google search result redirects, then you should post a virus removal request using the steps in the following topic rather than continuing with this guide:

    Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help Topic

    If TDSSKiller requires you to reboot, please allow it to do so. After you reboot, reboot back into Safe Mode with Networking again.

  7. 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)

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

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

  10. 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.

  11. 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.

  12. 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

  13. 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.

  14. You can now exit the MBAM program. If Malwarebytes did not prompt you to reboot your computer, please do so that you are back in normal mode.

  15. 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 Vista AntiSpyware 2012 & Win 7 Home Security 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.
