What is Antivirus'09?

Antivirus'09, otherwise known as Antivirus 09 or Antivirus 2009, is a rogue anti-spyware program that was discovered by security researcher Bharath, This program uses aggressive advertising and false scan results in order to scare you into thinking you are infected. At this time Antivirus'09 is advertised through the use of pop-ups that appear when browsing the web. These pop-ups will state that your computer has a security issue and that you should run an online anti-malware scanner. You will then be brought to a page that displays an advertisement that impersonates an online anti-malware scanner, and when it has finished scanning will state you have a myriad of infections and that you should download and install Antivirus'09 in order to protect yourself. Though this program is not currently advertised or installed through Trojans, we expect that in the near future Antivirus'09 will start to be promoted via malware.

  • The Antivirus'09 Program
  • Antivirus'09 Scanning Screen
  • Results from scan
  • Antivirus'09 Security Center
  • Security Warning
  • Security Warning #2
  • Installer for Antivirus'09
  • Fake online anti-malware scanner
  • Online scan summary screen
  • Fake alert showing a harmless file as an infection

When the program is installed it will be set to start automatically when Windows starts. Then when you log into Windows, the program will automatically start and scan your computer. When the scan has finished it will display numerous infections that cannot be removed until you purchase a license of Antivirus'09. The infections it finds, though, are actually false and the files it shows are either legitimate or do not even exist. This is because the program is scripted to state that you are infected by a selection of over 3,000 infection types that it are hard coded into the program. That means that even on a freshly installed and clean computer, Antivirus'09 will still state that your computer is infected. If this program states that files are infected, please ignore what it says as you may accidentally remove a legitimate Windows program. A sample of the infections it states are on your computer are:

Detected As
Detected As
C:\Windows\System32\cmdial32.dll Spy-25079 C:\Windows\System32\\System32\cmd.exe Win32.Agent.btlj
C:\Windows\\System32\clbcatex.dll Trojan.Small-51-3 C:\Windows\System32\cleanmgr.exe Bagle.AP
C:\Windows\System32\chkdsk.exe Win32.Hupigon.ggsw C:\Windows\System32\cfgbkend.dll Win32.KGen.iqq
C:\Windows\System32\CeEPDefDat.dll VBS.SST-A.3 C:\Windows\System32\ccPasswd.dll Win32.Rbot.abfn
C:\Windows\System32\camocx.dll Win32.Midgare.uym Win32.Flicker
Doc1.doc Win32.Flicker Calculations.xls Win32.Flicker
Work.xls Win32.Flicker C:\Windows\System32\bitsprx2.dll Win32.Buzus.aoni

While the program is running you will also constantly see security alerts and nag screens appearing on your screen. These screens are very disruptive as they will stay on top of any running programs until you acknowledge them. These nag screens range from stating that you are being hacked to malware processes being detected running on your machine. An example of the type of alert you will see is:

Malware or Advertising item was detected Antivirus'09

Malicious object can corrupt your computer files and documents, and steel <sic> your personal data such as credit card info or email accounts!

Antivirus'09 also installs a program called C:\WINDOWS\system32\SysShield.exe that displays a fake Windows Security Center. This security center window will attempt to appear as a helpful screen showing the latest virus threats and the status of the security on your computer. In reality, though, all this program does is further try to convince you to purchase the program.

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

  5. 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.

    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.

  8. 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 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.

  9. You can now exit the MBAM program.

Your computer should now be free of the Antivirus'09 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.
