System Restore error 0xc0000225 due to Anti Virus Update 0x80070005

0

Really need some advice, as I don't know what to do now!

I was using my computer as normal and had an Avast Anti Virus message pop up along the lines of, "Avast update restart computer?" I clicked on yes. On start up it showed a blue screen and the following system error 0xc0000225.

I then held down the power key and tried to trouble shoot by trying to restore the system to a previous date. I encountered the following error: "System restore could not access a file because an antivirus program is running on the computer. Temporarily disable your antivirus program and retry system restore. An unspecified error occurred during system restore (0x80070005)"

How would I disable the antivirus if I can't even get into my computer?

btw my operating system is windows 8.1

Thanks a million!

I had the same problem. I had a problem with my PC so I did a system restore without disabling Avast antivirus. I ended up getting a 0xc0000225 error, trying safe mode simply rebooted the computer. After doing every fix I could think of, system restore from boot drive, startup repair, chkdsk /r, sfc, manually copying system files.. all failed to fix the problem. I found a fix online that repaired the problem:

Boot from a recovery drive or DVD. (There are a lot of tutorials on how to do this.)

  1. Invoke command prompt.
  2. Run DISKPART and select your system drive (usually drive 0) with the command select disk 0 then enter the command list volume.
  3. Find the volume that is labeled "system reserved". It should be 100MB. Find the drive letter of this volume and select it with the command select volume # (replace the # symbol with the drive letter.).
  4. Assign it a new drive letter. Use any available letter, I will use X as my example. Enter the command assign letter x
  5. Exit diskpart. Enter the command exit This will get you back to the command prompt.
  6. Rebuild the system reserved partition. Enter the command bcdboot C:\windows /s x: /f uefi. Remember if you used a different drive letter than in my example, type it instead of X.
  7. Exit command prompt with the command exit and reboot the computer.

You will now have an additional option on your bootloader. You must select the new one that corresponds with the new system volume.
