Defraggler stops working While defragmenting C drive

Well, it works fine in D drive, but at some point when defragmenting C drive it just halts and then Windows instantly declared it dead.

I restarted Defraggler and tried to defrag C drive again. It went on with the pre-defrag analysis and then it crashed.

Defraging from the file list tab seems to work and not crash at all, except for a few files which it couldn't defrag: (But I doubt this course of action is recommended, right?)

  • {(numbers)}, 3.9GB [c:\System Volume Information\]

    From what I understand, this is the system restore savepoints?

  • 7 AVG9 log files

What do I do from here....?

Specs:

Windows 7 x64

Defraggler version: v1.19.192 x64
