"Enter Password" black screen login

Hey guys,

I tried booting up my PC which has Windows 8 installed and it was working fine until yesterday.

It has a "Enter Password" screen upon start-up and I think it's a virus because it only lets me enter 10 characters and even though, I do put in the correct password, it still says it's incorrect. The computer also shuts down after 3 unsuccessful attempts.

I have attached a picture of the screen.

Any help would be greatly appreciated!

I found out the issue is a BIOS password. I'm looking into making a HirensBootCD to get rid of it. Any suggestions?

I've now created the HirensBootCD and have it in my Toshiba laptop. I've tried booting to disk and accessing the BIOS but am unsuccessful even when I tried pressing and holding all of the F keys as well as ESC+F1...any ideas or suggestions are welcomed
