have you asked your mom what she was doing/installing before this started?
have you even looked in "programs and features" to see if there's anything recently installed that looks fishy?
have you run a malware and virus scan?
have you tried a restore point?
She doesn't remember.
Most of the icons on the Desktop are MIA in Safe Mode, so can't even get to Control Panel.
AVG caught, and I quarantined 3 trojans, and MalwareBytes caught, and I quarantined another 10 trojans.
Going back the six months to the most recent Restore Point would wipe out a lot of her work, and is not acceptable to her.
I'm a Linux guy, so don't know this OS well enough to solve this but, is it possible that during the Boot Sequence something is going wrong that causes the boot process to move to safe mode, over and over again? If so, is there an Error Log that I could get to with a Keyboard Shortcut, where I could browse the latest error listings, as I probably can't touch the icon I need?
