im just gonna say this once
theres not a virus or a computer problem that i couldnt solve in my 20 years of experience, by goggling.
goggle shit up and if it doesnt work, try again tomorrow. im 200% sure someone has fucked those virus makers already with a good solution.
or, id fix the thing for you, id virus myself if need be to find the solution, id charge you $100 paypal. i have a reputation here. have fixed other people's shit before. 82[is] paypalled me $60usd to fix his video card problem about 3 years ago... you can ask
but, i can think of something that may work that you can try. i stumbled into an encrypting virus once.
all i had to do was, download a linux distro, boot with it, and all the files were readable and copyable. (were in a diff folder tho)
you could try with a small short linux like "Damn Small Linux" which is about 50megs but its somewhat limited, and unfriendly
i recommend, WIFIWAY or KALI LINUX
for making the usb bootable, again.. use goggle.... kali linux usb etc..
or use a program called, UNETBOOTIN to make the usb from the images
