Hi,
Following instructions assume you have recovery console installed (there should be microsoft recovery console option selectable when you boot the system). Please print/save these so you have access to them while system is not online.
1. Restart your computer
2. Before Windows loads, you will be prompted to choose which Operating System to start
3. Use the up and down arrow key to select Microsoft Windows Recovery Console
4. You must enter which Windows installation to log onto. Type 1 and press enter.
5. At the C:\Windows prompt, type the following bolded text, and press Enter:
copy C:\WINDOWS\system32\drivers\volsnap.sys C:\WINDOWS\system32\drivers\volsnap_old.sys
You should see "1 file(s) copied." message as an output. Let me know if something else happened.
6. At the next prompt, type the following bolded text, and press Enter (allow overwriting when prompted):
copy C:\WINDOWS\system32\dllcache\volsnap.sys C:\WINDOWS\system32\drivers\volsnap.sys
Again, the same thing should happen as after the previous step.
7. If no issues with that then at the next prompt, type the following bolded text, and press Enter:
exit
Windows will now begin loading. Please run GMER again and post back its report.
