What this infection does:
Antivirus7, or Antivirus 7, is rogue anti-spyware program
from the same family as the Antivir
rogue. This program is promoted through the use of web sites that pretend
to be online anti-malware scanners. You will typically get to these pages through
web pop-ups that state that your computer is infected and that you should run
an online scan. When you click on this pop-up you will automatically be brought
to a page showing an advertisement that pretends to be an online anti-malware
scanner. When this fake scanner finishes it will state that you are infected
and that you should download and install Antivirus7 to protect your computer.
When Antivirus7 is installed it will be set to start automatically when you
login to Windows. Once started it will scan your computer and state that there
are a variety of infections on your computer, but will not remove them until
you first purchase the program. These infections are all fake, though, and the
files it states are infected are actually legitimate Windows programs. Therefore
please do not manually delete any of the files it states are infections as it
may cause your Windows operating system to not operate properly.

For more screen shots of this infection click on the image above.
There are a total of 7 images you can view.
While Antivirus7 is running it will also display numerous fake security warnings
on your Windows desktop. These alerts will state that a virus has been detected,
that there was an Identity theft attempt, or that important critical updates
for your computer are ready to be installed. The text of some of these alerts
are:
Resident Shield: New virus detected
Warning! New virus detected
Please click "Remove All" button to heal all infected files and
protect your PC
Internet Shield: Identity theft attampt detected
56.12.121.12
Warning! Identity theft attempt detected
Please click "Prevent attack" button to heal all infected files
and protect your PC
Security advisor: Important updates available
Attention! New important updates available
Always install latest updates to enhance your computer secutity and performance
Just like the scan results, these fake security alerts are all fake and are
only being shown to further scare you into thinking that there is something
wrong with your computer. With this said, please ignore these messages.
As you can see, Antivirus 7 was created with one thought in mind; to scare
you into thinking you are infected so that you will then purchase the program.
Please do not purchase this program, and if you already have, please contact
your credit card company and dispute the charges. Finally, to remove the Antivirus7
infection, please use the steps in the removal guide below.

Automated Removal Instructions for Antivirus7 using Malwarebytes' Anti-Malware:
- 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
Antivirus7
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
Antivirus7
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
Antivirus7
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
Antivirus7
. 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.
- Now you should download Malwarebytes' Anti-Malware, or MBAM, 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
this one.
- 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 both the
Update Malwarebytes' Anti-Malware and 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 automatically start and you will see a message stating that
you should update the program before performing a scan. As MBAM will automatically
update itself after the install, you can press the OK button
to close that box and you will now be at the main program as shown below.
- On the Scanner tab, make sure the the Perform
full scan option is selected and then click on the Scan
button to start scanning your computer for
Antivirus7
related files.
- MBAM will now start scanning your computer for malware. This process can
take quite a while, so we suggest you go and do something else and periodically
check on the status of the scan. When MBAM is scanning it will look like the
image below.
- When the scan is finished a message box will appear as shown in the image
below.
You should click on the OK button to close the message box and continue with
the
Antivirus 7
removal process.
- You will now be back at the main Scanner screen. At this point you should
click on the Show Results button.
- A screen displaying all the malware that the program found will be shown
as seen in the image below. Please note that the infections found may be different
than what is shown in the image.
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.
- When MBAM has finished removing the malware, it will open the scan log and
display it in Notepad. Review the log as desired, and then close the Notepad
window.
- 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 7
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.
If you are still having problems with your computer after completing these instructions, then please follow the steps outlined in the topic linked below:
