AntiVirus System 2011 is a rogue anti-spyware program that displays fake scan results and alerts in order to trick you into thinking your computer is infected. This program is installed through Trojans that download and install the program on to your computer without your permission. When installed, the rogue will also create numerous files in your Windows Temp folder that will then be detected as malware when AntiVirus System 2011 attempts to scan your computer. If you attempt to remove any of the programs it states are infections, it will state that you need to purchase the program first before it will allow you to do so. The reality is that these files are harmless, or do not even exist, and are only being shown to scare you into purchasing the program.
While running, AntiVirus System 2011 will also display fake security alerts on your computer. These alerts are designed to make you think that you have a severe computer infection or that your computer is sending private data to a remote location. The text of these alerts include:
Unauthorized remote connection!
Your system is making an unauthorized personal data transfer to a remote computer!
Warning! Unauthorized personal data transfer is detected! It may be your personal credit card details, logins and passwords, browsing habits or information about files you have downloaded.
To protect your private data, please click "Prevent Connection" button below.
Security Center Alert
To help protect your computer, Security Center has blocked some features of this program.
Just like the fake scan results, these alerts are fake as well and only shown to scare you into purchasing the program.
Without a doubt, this program is a scam that was developed to scare you into purchasing it. Therefore, do not purchase AntiVirus System 2011 for any reason, and if you already have, please contact your credit card company and state that the program is a computer infection and a scam and that you would like to dispute the charge. To remove this infection and related malware, please follow the steps in the 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 may need to close every window that is
open later in the fix.
- 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
AntiVirus System 2011
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
AntiVirus System 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
AntiVirus System 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
AntiVirus System 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-1878.1878-188.8.131.529.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 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 AntiVirus System 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.
