Smart Engine is a rogue anti-spyware from the VirusDoctor
family. This rogue is installed through the use of Trojans that impersonate
video codecs or software updates required to watch videos online. When you run
the program, though, it does not install any legitimate software but instead
downloads and installs Smart Engine onto your computer without your permission
of knowledge. While installing, Smart Engine will also create numerous harmless
files that are meant to impersonate virus infections on your computer. The names
of these files include:
%UserProfile%\Recent\ANTIGEN.dll
%UserProfile%\Recent\ANTIGEN.drv
%UserProfile%\Recent\cid.tmp
%UserProfile%\Recent\CLSV.exe
%UserProfile%\Recent\CLSV.sys
%UserProfile%\Recent\DBOLE.drv
%UserProfile%\Recent\delfile.sys
%UserProfile%\Recent\eb.sys
%UserProfile%\Recent\energy.exe
%UserProfile%\Recent\exec.exe
%UserProfile%\Recent\fan.drv
%UserProfile%\Recent\kernel32.dll
%UserProfile%\Recent\pal.exe
%UserProfile%\Recent\PE.dll
%UserProfile%\Recent\ppal.drv
%UserProfile%\Recent\tempdoc.tmp
Smart Engine will then be configured to start automatically when you login
to Windows. Once running, the program will scan your computer and list the files
listed above, which it created in the first place, as infections. Smart Engine,
though, allow you to remove anything until you first purchase the program. The
fact that Smart Engine detects the files it created in the first place as infection
shows that this program is nothing more than a scam and should be ignored.

There are a total of 7 images you can view.
While Smart Engine is running it will also display numerous fake security warnings
that contain messages that attempt to make you think your computer has a serious
security problem. The text of these messages include:
System Alert
malicious applications, which may contain
Trojans, were found on your computer and are to be removed immediately. Click
here to remove these potentially harmful items using Smart Engine.
System Alert
Firewall has blocked a program from accessing the Internet.
Internet Explorer
C:\Program Files\Internet Explorer\Iexplore.exe
Lsas.Trojan-Spy.DOS.Keycopy is suspected to have infected your PC. This type
of virus intercepts entered data and transmits it to a remote server. Data
interception was detected while visiting a website.
Warning
Warning! Virus detected
Threat Detected: Trojan-PSW.Win32.Delf.d
Just like the fake scan results, these fake security messages are all fake
should be ignored.
Without a doubt, Smart Engine was created to scam you into purchasing the program
by making you think your computer is infected. It goes without saying that you
should definitely not purchase Smart Engine, 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 any related malware, please follow the steps in the guide below.

Automated Removal Instructions for Smart Engine 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
Smart Engine
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
Smart Engine
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
Smart Engine
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
Smart Engine
. 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. Do not reboot
your computer after running RKill as the malware programs will start again.
If you continue having problems running RKill, you can download the other
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.
- 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
Smart Engine
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
Smart Engine
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 this infection also changes your Windows HOSTS file, we want to replace
this file with the default version for your operating system. Please note
that if you or your company has added custom entries to your HOSTS file then
you will need to add them again after restoring the default HOSTS file. In
order to protect itself,
Smart Engine
changes the permissions of the HOSTS file so you can't edit or delete
it. To fix these permissions please download the following batch file and
save it to your desktop:
hosts-perm.bat
Download Link
When the file has finished downloading, double-click on the hosts-perm.bat
file that is now on your desktop. If Windows asks if you if you are sure you
want to run it, please allow it to run. Once it starts you will see a small
black window that opens and then quickly goes away. This is normal and is
nothing to be worried about. You should now be able to access your HOSTS file.
- We now need to delete the C:\Windows\System32\Drivers\etc\HOSTS
file. Once it is deleted, download the following HOSTS file that corresponds
to your version of Windows and save it in the C:\Windows\System32\Drivers\etc
folder. If the contents of the HOSTS file opens in your browser when you click
on a link below then right-click on the appropriate link and select Save
Target As..., if in Internet Explorer, or Save Link As..,
if in Firefox, to download the file.
Windows
XP HOSTS File Download Link
Windows
Vista HOSTS File Download Link
Windows
2003 Server HOSTS File Download Link
Windows
2008 Server HOSTS File Download Link
Windows
7 HOSTS File Download Link
Your Windows HOSTS file should now be back to the default one from when Windows
was first installed.
- Now reboot your computer.
- 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
Smart Engine
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:
