Antivirus 360 is a rogue anti-spyware program that uses false
scan results and aggressive advertising in order to promote itself. This rogue
is advertised by the Vundo
Trojan and is replacing the Antivirus 2009 rogue program that Vundo has
been aggressively advertising. If you are infected with the Vundo Trojan you
will see a large amount of pop-ups stating that your computer is infected and
that you should install Antivirus 360 in order to protect yourself. If you click
on the ad, Antivirus 360 will be downloaded to your computer and you will be
prompted to install it.
Once installed, Antivirus 360 will be configured to start automatically when
you start Windows. Once started, the program will perform a scan, and when done,
will list a variety of legitimate or nonexistent files as infections that cannot
be removed unless you first purchase the program. What is so dangerous about
these scan results is that the files that Antivirus 360 states are infections
are actually legitimate Microsoft files, that if deleted, will cause Windows
to become unusable. Therefore, if someone believes the results from this program
they may manually delete the files thinking they are infections and cause their
computer to no longer function. Some files that it states are infections are:
While running you will also see a constant barrage of false security alerts
stating that your computer has a variety of security risks. These risks range
from files being modified to private data being sent to a remote host. These
alerts, though, are false and are only being shown to further scare you into
thinking your infected, when in fact the Antivirus 360 program is the actual
infection. Unfortunately, these alerts coupled with the Vundo Trojan will affect
your computer's performance and you will notice that it begins to operate slower.

Automated Removal Instructions for Antivirus 360 using Malwarebytes Anti-Malware:
- Print out these instructions as we will need to close every window that
is open later in the fix.
- 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 mbam-setup.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 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
- You can now exit the MBAM program.
Your computer should now be free of the Antivirus 360 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.
