This was related to mvsync.sys I can find little information about this driver so it may be malware. I would run Malwarebytes and do a system file check
Please download the free version of Malwarebytes.
Update it immediately.
Do a full system scan
Let us know the results at the end.

Please run a system file check (SFC) & DISM (if necessary) if you are on win 8 or higher
All instructions are in our Wiki article below...
Should you have any questions please ask us.
