Security Essentials can't remove/quarantine "Adware:Win32/FastSaveApp"
Each time I switch on my PC Security Essentials flags up an medium alert (status active) concerning a detected item - "Adware:Win32/FastSaveApp".
I've applied the action "Quarantine" and "Remove", each time Security Essentials completes the operation and tells me to restart my PC.
Upon restart FastSaveApp is back again.
I have tried CCleaner and Malwarebytes but they don't pick it up. I've check to see if it has installed anything in Chrome and IE9, it hasn't as far as I can tell.
This is the first time that I've come across something that Security Essentials couldn't deal with. Any suggestions as to how I can remove this pest please?
