This rootkit has been very fun to follow thus far.
The CLSID / user-mode backdoor only variant does some interesting stuff to certain anti-malware tools, like OTL and MGtools. I took some footage here
Attaching a log from MGtools that gets messed up due to this variant. Enjoy!

Is detected but does not appear to exist (as an image only) Combofix logs in the list but does not find the file to delete it

Is the user's internet broken? According to yorkyt, afd.sys is present (but do not know if it is legit copy). Do you need help or are you just pointing out the .vir and .org extensions to afd.sys?
Last I checked, yorkyt adds a .bad extension to the files (not .vir or .org)
Side note: Looks like the user installed Norton midway through procedure (according to ComboFix2.txt).

The afd.sys.vir and afd.sys.vir was present before the use of yorkyt
First combofix log (combofix.txt) and MSE detections were run before asking for help online, as were TDSSkiller, spyhunter Hitmanpro and whatever else,
Order oldest to newest log at bottom
combofix.txt
MSE Detections.txt
aswMBR.txt
yorkyt.exe.log
combofix2.txt
The user has the internet.
I am just point it out at the moment
FSS.txt attached, afd.sys is legit
