WinFixer (also known as the Vundo Trojan) is
related to Adware. Adware comes through corrupt sites and
installs itself without the users' agreement. Adware parasites
perform actions related to data recorded about the user.
Gathered information can be related to browsing
history, the most visited pages, the products bought and more...
Adware has the opportunity to update itself without user consent
and attack you with newly updated ads in an ongoing cycle.
WinFixer behavior and symptoms are:
· Browser performance can be slow
· Possible pop-up ads display, search redirects
· Windows errors can be caused
· System crashes and restarts can occur
Every time the computer is booted up, WinFixer
pops up and tries to run its installer. It can be closed, but
sometimes that does not work, or if accidentally the wrong
button is pressed WinFixer begins the installation process.
Rebooting while it is trying to install is the only thing that
will stop it. The process starts all over again after computer
restart. WinFixer shows popup ads even if the main product is
not running. Removing it multiple times using Add/Remove
programs does not help, because it keeps coming back.
Here's the worst part: WinFixer is one of the
more serious viruses affecting your registry and system files,
and making removal much more complex.
If you are familiar with computers, and are able
to edit your registry the removal steps are listed below - if
you are not this familiar with computers, please see someone who
is, or take it to a retailer.
Removal steps for WinFixer are as follows:
-
This guide fits for Windows 2000 and XP
versions. Firstly you have to create Hijackthis log.
(Download
HijackThis)
-
Locate O2 - BHO: MSEvents Object line in the
log. If such line is not found terminate reading this
paragraph and jump to Manual WinFixer removal on the bottom
of the page.
-
O2 - BHO: MSEvents Object is the line where
WinFixer is hiding. Whole line should look like this O2 -
BHO: MSEvents Object -
{827DC836-DD9F-4A68-A602-5812EB50A834} -
C:\WINDOWS\system32\zxcvb.dll, but the
{827DC836-DD9F-4A68-A602-5812EB50A834} and
C:\WINDOWS\system32\zxcvb.dll parts can be different from
the lines you can see on your log file. All you have to do
is write the second part (C:\WINDOWS\system32\zxcvb.dll)
down and use it INSTEAD of C:\WINDOWS\system32\zxcvb.dll in
the future
-
Download
VundoFix.exe to your desktop and run the file to
extract VundoFix. All extracted files will be located on the
desktop.
-
Reboot the computer into safe mode by
choosing "Restart" option and pressing F8 key until menu
appears. Choose "Safe Mode" and hit "Enter".
-
After computer is booted up, go to VundoFix
folder and run KillVundo.bat file. First a caution window
will appear - press "Enter". Further you will be asked to
enter the line that you have written down in the third step.
After the line is entered press "Enter". A message "Please
type in the second filepath as instructed by the forum
staff" should appear.
-
Now type the same line as you did before,
but the "zxcvb" part (you have to use your own discussed in
third step) writing in reverse order - "bvcxz" and replacing
"dll" extension with *. So the final line will look like
C:\WINDOWS\system32\bvcxz.* Press "Enter".
-
Finally HijackThis will be launched
automatically (if not - start it manually). After scan if
you can locate lines
O2 - BHO: MSEvents Object -
{827DC836-DD9F-4A68-A602-5812EB50A834} -
C:\WINDOWS\system32\zxcvb.dll
O20 - Winlogon Notify: C:\WINDOWS\system32\zxcvb.dll
Check them and press "fix checked".
ATTENTION! the C:\WINDOWS\system32\zxcvb.dll part on the
both lines has to be the same as you have written down in
the third step.
-
Reboot the computer
