AV Security Suite is a scareware and ransomware program from
the same family as Antivirus
Soft and AntiSpyware
Soft. The developers of this program are distributing AV Security Suite
through the use of hacked sites, spam, and Trojans that install it onto your
computer without your permission. Once installed AV Security Suite will be configured
to start automatically when your computer starts. Once started it will scan
your computer and state that there are numerous infections, but will not let
you remove any of them until you purchase the program. All of these scan results
are fake and are only being shown to trick you into purchasing the program,
which you should obviously not do.
If you are running older software, and not updating Windows, you may find
that you will be able to remove this program, but then become infected again
within a short period of time. This is because the malware developers are hacking
legitimate sites or inserting malware ads that use vulnerabilities in common
programs such as Adobe Reader, Flash, and Windows to install the malware onto
your computer. If you do not update your programs to remove these security holes
then the next time you visit a hacked site distributing this rogue, AV Security
Suite will be installed on to your computer. A great tool that can be used to
scan your computer for outdated and vulnerable programs is the free Secunia
Personal Software Inspector program. When you scan your computer with this program
it will display a report showing all programs and Windows updates that should
be installed in order to fix security holes and vulnerabilities. It is advised
that all users scan their computer with this program in order to prevent your
computer from being infected again after you clean it. A guide on how to install
and use this program can be found here:

When AV Security Suite is running it will also block you from running normal
tasks in order to make it harder to remove the program from your computer. First,
it configures Windows to use a proxy server that points back 127.0.0.1:1041.
A proxy server is a program that listens to requests from your web browser and
then handles the request itself rather than your browser talking directly to
a site. As AV Security Suite is set to be your proxy server, any time you browse
the web using Internet Explorer it will intercept the request and display a
fake security warning that states that the site you are visiting is infected.
The message it will display is:
This website has been reported as unsafe
We recommend that you do not continue to this website. This website has been
reported to Microsoft for containing threats to your computer that might reveal
personal or financial information.
Once you disable the proxy server all web requests will go directly to the
site you wish to go to and you will see the legitimate content. Please note,
though, that the next time AV Security Suite is started it will configure your
computer to use the proxy server again.
The second method that AV Security Suite protects itself is to block applications
from running while stating that they are infected. It does this to stop you
from running anti-virus programs that can be used to remove this malware. When
you attempt to run a program you will instead see the following message:
Windows Security alert
Application cannot be executed. The file mbam.exe is infected.
Do you want to active your antivirus software now?
Application infected! The file rundll32.exe is infected. Do you want to ALLOW
this application now?
When you see these infection alerts do not be concerned as your programs are
not infected. It is only showing this to further scare you into thinking you
have a computer security problem.
While started, AV Security Suite will also display fake security alerts that
contain warnings that malware has been detected or that malware is attacking
your computer. These messages are all fake as well and only being shown to further
convince you that your computer is infected. The text of these messages are:
Windows Security alert
Windows reports that computer is infected. Antivirus software helps to protect
your computer against viruses and other security threats. Click here for the
scan your computer. Your system might be at risk now.
Antivirus software alert
Your computer is being attacked by an internet virus. It could be
a password-stealing attack, a trojan-dropper or similar.
Last, but not least the rogue will also display a fake Windows Security Center.
This fake Security Center will look exactly like the original one except that
it states that you should purchase AV Security Suite to protect yourself.
As you can see, AV Security Suite was created for one reason only; to scare
you into thinking your computer has numerous infections so that you will then
purchase the program. It goes without saying that you should definitely not
purchase this program, and if you already have, please contact your credit card
company and dispute the charges stating the program is a scam. Finally, to remove
this infection please use the removal guide below to remove it for free.

labeled iExplore.exe download link. When you are prompted
where to save it, please save it on your desktop.

and do steps 3-6 again and make sure the infection has not reenabled the proxy
settings. You may have to do this quite a few times before you can get RKill
downloaded. If you still cannot download the RKill program on the infected
computer, you should download it to a clean computer and copy it to the infected
one via a USB flash drive or CDROM.
- Once it is downloaded, double-click on the iExplore.exe
icon in order to automatically attempt to stop any processes associated with
AV Security Suite
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
AV Security Suite
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

renamed versions of RKill from the RKill
download page. Both of these 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.

location and save it to your desktop:
Malwarebytes Anti-Malware Download Link
