So I have an extremely resilient Trojan horse and malware on my pc. I do not know what day or how I got it there so I can't backup. To give you an idea of how powerful this virus is, it has installed a program to multiply in the task manager and it takes up all my CPU usage. Then this virus has somehow disable me being able to use advanced startup (it just restarts pc, doesn't bring me to troubleshooting menu) Then also any antimalware or anything that could possibly wipe it out has been blocked. If I try to run malwarebytes or any programs like adwcleaner etc, it gives me the error "the requested resource is in use" This applied for kaspersky rescue disk. I had to create the USB on another pc. But when I boot into my bios (cmos setup utility) and change the boot sequence to the USB first, then cd-rom, then sata drive. When I boot up I just get a blank screen. There is no cursor but there is this white underscore line that blinks, like I'm supposed to type something. How do I fix this?
