I'd red your post, and badly I cannot reply there (since I just registered) but I'd wanted to let you know, that I have been dealing (as i think) with the exact same problem!
For me it worked this way:
- Boot up (after some seconds your whole desctop dissapears rite?)
- Press Ctrl+alt+del
- Go to the option "execute new task"
> then browse to either IE or Mozilla (if you want to go on the internet) or go to the disc where u have the files u need to get rid of the virus
What I did:
- (Read alot) and downloaded Malewarebytes Anti-maleware
-> installed
-> Scanned (quick scan should be enougt) then It detected around 18 trojans, -> stop scan and remove them. Two of them couldn't be deleted rite then, but on a reboot.
Reboot and then ur system should be 'normal'.
But this is only step one. After that the system will still be infected, so make sure to ask for help (since I don't know how to get totaly rid of it).

Well, good luck...
