After running adware (on toshiba laptop win10 64 bit) it found a pup and when I clicked clean it required a reboot.  On reboot it black screen. I've tried turning off, waiting and turning back on. Black screen. I've tried f2, 8,10,12 with shift key and without when turning back on. Black screen. Help!!

Hello,

Do you remember what detection was it?

Do you manage to boot in safe mode? See: https://www.howtogeek.com/107511/how-to-boot-into-safe-mode-on-windows-8-the-easy-way/

If so, can you:

1. copy the folder C:\AdwCleaner to an USB key and send it to me from another computer,

2. Create a USB repair key as explained here: https://www.tenforums.com/tutorials/4200-create-recovery-drive-windows-10-a.html

Thanks,
