What is System Protector?
System Protector is a rogue anti-spyware program that is
installed and promoted through the use of Trojans. These Trojans will display
fake security alerts and warnings on your computer, and then when clicked on,
will download and install System Protector without your permission. Once installed,
the program will be set to start automatically and to scan your computer. When
the scanning has finished, it will state that your computer has numerous infections
and will not remove them unless you purchase the program. These infections,
though, are all false and do not even exist on your computer. System Protector
also utilizes built-in removal protection by blocking proper access to certain
anti-malware sites and tools. In order to bypass this protection you simply
need to end the program's process so that you have proper functionality of your
browser. Our guide below will explain how to do this. When the program is running
you will also constantly see nag screens appearing stating that your computer
is infected or has another problem. These nag screens are all fake warnings
and should be ignored as well.
Some installations of System Protector include a DLL that is loaded via the
Winlogon Notify key. This DLL has a random name and is located in the C:\Windows\System32
folder. If this DLL is loaded it will make it so you cannot run numerous anti-malware
programs on your computer. An example HijackThis entry for this type of DLL
O20 - Winlogon Notify: aeefaaeeafcbba - C:\WINDOWS\system32\aeefaaeeafcbba.dll
If you have problems starting anti-malware utilities or if they shut down automatically
when you start them, then you may have this module installed. If this is the
case you will need to delete this file before following the rest of the steps
in this guide. For help removing and identifying this DLL, we suggest you ask
about in the forums. Otherwise, please use the following guide to remove System
Protector and any associated malware for free.
