Can you access the PC? Are you able to use the internet i.e. to download and run tools? If yes, please follow this thread.
Sorry, was going to post something again until the computer died there.
If what Valinorum says, doesn't work, then try Safe Mode with Netorking, if that doesn't work. Download the files onto a USB using a second computer, then boot into Safe Mode with Command Prompt. When the CMD pops up, type "explorer.exe" (Without the quotes!). Then transfer the files and post back the logs so Valinorum can remove it
