PC Security 2011 is a fake rogue anti-spyware program from the same family as Win7 AV. This rogue utilizes web pages that host exploit kits that attempt to exploit vulnerabilities in your Windows operating system or in programs that may be installed on your computer in order to install PC Security 2011 on to your computer without your permission. Once the rogue is installed it will be configured to start automatically when Windows starts. Once started it will scan your computer and display numerous infections, but will state that you first need to purchase the program before you can remove any of them. As these scan results are all fake, you should not purchase this program based on anything that is displayed.
In order to protect itself PC Security 2011 will also terminate many programs when you launch them. It does this in order to protect itself from security programs that you may attempt to run in order to remove this infection. When it terminates a program it will display the following alerts that states the program is infected or has crashed:
PC Security 2011 - Runtime protection
PC Security 2011 has blocked spyware activity for this program.
iexplore.exe is probably infected with Conficker.B virus. This worm attempts to send your personal information to remote host through iexplore.exe.
Windows TaskManager has encountered a problem and needs to close. We are sorry for the inconvenience.
Just like the fake scan results, these infection messages are just another tactic to protect itself and scare you into thinking your infected.
While running, PC Security 2011 will also display a continuous stream of security alerts and nag screens that contain messages that state your computer is severely infected or that applications are sending private information to a remote computer. The text of some of these alerts, including their spelling and grammatical errors, include:
Warning! Adware Detected!
Netsky.Q.adware has been detected on your PC. A is a spyware program that may perform opening of a number of website popup's and ad's.
Windows Defender Warning

In order to ensure that your Windows system has highest level of protection, you should update your security software regulary.
Sality.AM virus Spyware detected.
Spyware try to hide associated malicious programs.
All of these alerts should be ignored when you see them as they are just trying to scare you into purchasing the program.
Without a doubt, PC Security 2011 was created for one reason; to scare you into thinking your computer is infected so that you will then purchase the program. It goes without saying that you should absolutely not purchase this program, and if you already have, you should contact your credit card company or payment company and dispute the purchase stating that the program is a computer virus and a scam. Finally, to remove this infection and related malware, please use the removal guide below.
Self Help Guide
If you are uncomfortable making changes to your computer or following these steps, do not worry! Instead you can get free one-on-one help by asking in the forums.
- Print out these instructions as we will 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 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.
- Now we must first end the processes that belong to
PC Security 2011
and clean up some Registry settings so they do not interfere with the cleaning
procedure. To do this, please download RKill to your desktop from the following
RKill Download Link - (Download page will open in a new tab or browser window.)
When at the download page, scroll down and click on the click on the link labeled eXplorer.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
icon in order to automatically attempt to stop any processes associated
PC Security 2011
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
PC Security 2011
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
PC Security 2011
. 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.
- 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)
- Once downloaded, close all programs and Windows on your computer, including
- Double-click on the icon on your desktop named mb3-setup-1878.1878-18.104.22.1689.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.
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.
- 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 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,
PC Security 2011
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:
- 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.
Windows XP HOSTS File Download LinkYour Windows HOSTS file should now be back to the default one from when Windows was first installed.

- 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 PC Security 2011 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.
