Yesterday, I had a few malwares and trojans infecting my computer, after i removed them with Malwarebytes' Anti-Malware a pop up which says;
Bad Image
The application or DLL C:\PROGRA~1\KASPER~1\KASPER~1\mzvkbd3.dll is not a valid Windows image. Please check this against your installation diskette.
This error message constantly appears every time I start up my computer or open up every application or program.
I downloaded DDS and analyzed my PC. Here's my log;
