A couple of weeks ago I was away from my 4-year old Acer Aspire ATC-605-UR1A Desktop PC for a couple of hours and when I returned there was a message in the lower-right hand corner of the screen that I'd never seen before that said something like "Super AntiSpyware has found a trojan and...." Before I could finish reading the rest of the message, my PC suddenly shut off by itself and I've been unable to reboot it ever since.
I'm using Windows 7 Pro 64 bit and I'm getting the 0xc000000d error message when I turn the PC on ["An error occurred while attempting to read the boot configuration data."]. I learned about the Hiren Boot CD, downloaded it and used the Rufus app to put HBCD on a USB flash drive, but the computer doesn't seem to recognize the flash drive even though I adjusted the BIOS to boot the computer from the USB device [or Removable Device]. It just keeps giving me this message: "Reboot and Select proper Boot Device or Insert Boot Media in selected device and press a key." I've already done that and I keep ending up back at that screen with that message.
Don't know what else to do. There have been no recent software changes on the computer. I need to rescue the files I worked on before my last backup. The SuperAntiSpyware trojan message that began all this might have been a coincidence. I also use MalwareBytes and ZoneAlarm antivirus software. I've already tried opening the computer and dusting inside and re-seating things to no avail.
Can anyone help?
