Virus Sweeper is a rogue program that is a clone of Virus
Alarm and Virus
Doctor. These particular rogues are notorious for their use of Google
Code to distribute its software. Google Code is a programming project repository
that allows programmers to host files related to their projects. Virus Sweeper's
installer then uses Google Code to download and install the program onto your
computer. Only when the program can't be downloaded from Google Code will it
then utilize other servers that are under the malware writer's control. When
the program is installed it will also create a variety of files randomly throughout
your computer. These files are harmless but will be used by Virus Sweeper to
be detected as infections.
Virus Sweeper screen
For more screen shots of this infection click on the image above.
There are a total of 6 images you can view.
Once the program is installed it will be configured to start automatically
when you log into Windows. When running, it will perform a scan and list a variety
of malware found on your computer, but will not remove them until you purchase
the program. The malware files it finds, though, are actually the harmless fake
malware files that it created on your computer in the first place. While running
you will also see nag screens and fake security alerts appear on your computer.
These alerts are being shown to further scare you into thinking your computer
is infected. Just like the scan results, any security warnings and pop-ups you
see from this program should be ignored. Instead, please use the removal guide
below to remove Virus Sweeper from your computer for free.

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.
- 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
Virus Sweeper
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 VirusSweeper 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.
Your computer should now be free of the VirusSweeper 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.
