Manually
removing viruses and malware from your computer. If you want to use an
anti-virus program instead, please check out this tutorial written by
Burritobob. This tutorial's best intention is focused around removing RAT and
Keylogger viruses.
Step
1
Run
msconfig and look for suspicious files. Here we see one. It’s unknown, and it
also has a startup key that we’ve never seen until recently. Uncheck it from
start up and/or from services.
If
you think you are being monitored. Open Command Prompt and do the following
Step
2
Boot
into safe mode. This can be done by checking the box in the “boot” tab in
msconfig.
Step
3
Run
msconfig in safe mode and we can see it’s checked because the virus is
persistent. The virus will not be running however, due to the fact that we
are currently in safe mode.
Step
4
Navigate
to the registry. We are doing this in safe mode because some viruses disable
the registry.
Note:
Be sure your folder options are set to show hidden files and folders
Step
5
Navigate
to the location of the virus. If you are not sure which one is a virus,
locate to all of the following possible locations:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServicesOnce
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Runonce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunServices
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunServicesOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\Run
Step
6
Section
a) if you are unsure if it is a virus of not, right click the suspected
file{s} and click modify
Since
you are unsure of the integrity of the file, put a “:” in front of the value
data. This will disable the start up of the virus but it will still be in
your computer.
Section
b) if you are certain that you’ve found the virus (like I have in the
picture) you can delete the registry entry.
Step
7
Be
certain it is gone; it shouldn’t even be listed as a startup item anymore.
Step
8
To
be certain, use CCleaner to scan the registry and fix any issues there are.
