GenEncSF.sys is associated with JetFlash220 (a USB flash drive with a fingerprint sensor).
Please uninstall that (the JetFlash220) software and remove the device from your system.
Feel free to install the latest, Win7 compatible version after the system has been stabilized again.
PTFD.SYS belongs to a program called VirtualDrive - but there's not much info available on that.
What do you have on your system that could contain it? Please uninstall that to see if it helps.
I suspect it's associated with the JetFlash220 because of this page: http://siteadvisor.es/sites/transcend.com.tw/downloads/34246646/
IMGSF.sys is unknown, but I also suspect it's associated with the JetFlash220 because of this page: http://siteadvisor.es/sites/transcend.com.tw/downloads/34246646/
EDIT: I'll be adding these to the DRT shortly.....
