WinFixer

Behaviour
This misleading application can be manually downloaded and installed.

The program falsely reports a number of infected objects on the computer.



The program reports the following items as System threats:

• Invalid explorer extensions
• Invalid system files

It then prompts the user to purchase a registered version of the software in order to remove the reported threats.

Next, the program creates the following registry entry so that it executes whenever Windows starts:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\"WinFixer 2005" = "C:\Program Files\WinFixer 2005\WFX5.exe"

The program then creates the following registry subkeys:
