|You're not screwed...Tap f8 on startup and then choose safe mode with networking.|
If you can get in to safe mode, click start/run and type in msconfig. Once in there, turn off ALL of the start up items, don't reboot yet.,
Google for the following
Download these other free progs:
2- tdss killer
4- Trojan Remover
5- Hitman Pro.
Once they are downloaded install malwarebytes and do a quick scan and remove all it finds. Then reboot
Once you reboot to the normal scree,. run rkill.exe to shut down the process
Then run tdss killer
Now run Malwarebyes again, only this time do a full scan and remove all it finds.
Then run the last two on the list untill they are clean.
If by chance safe mode with networking does not work, use a different PC and put those utilities on a thumb drive and then install them on your laptop.
The best advice when you run in to a problem like you have...be sure NOT to click on anything on the desktop as it will get embedded in your registry.
Just shut down your PC and reboot and it will be gone.
