Finally, I fixed the problem that some pages were accidentally closed due to the "sysfader: assumer.exe" error.

Sysfader.exe is attached to the NVIDIA graphics card driver.ProgramIs used to process the fade-in/fade-out effects of the desktop and the balloon prompt bar. Normally, it will not cause errors during the process.
1. If your system is windows, right-click "properties"> "effects"> "Visual Effects" on the desktop. the fade-out effect is canceled.
2. If your system is Windows XP, right-click "my computer" and click "properties/advanced". In the "performance" column, click "Settings/Visual Effects" to cancel all special effects.
3. If you have used a third-party theme or modified the icon, restore the Windows default.
4. You can try to reinstall the video card driver.
5. Scan and kill Trojans.

I used the "360 security guard" scan to find "winp advertising software ":
(1) the "clean now" here cannot be cleared directly.
(2) The Trojan is located in C:/program files/ywhn by using the kill tool, but the trojan cannot be cleared.
(3) Restart to secure mode to delete the virus directory and then use "360 security guard" to clear the directory!

Conclusion: In security mode, use "360 security guard" to clear it.
