Good morning everyone!
Remembering that my language is not English. . . which may hinder a little communication.
Dell Inspiron N4050, Windows 7-64, Home basic.
Initially "C" (system), increased from one moment to another, the volume.
Observed that it was one of the restore points, which used no less than 30 GB, only he, and all together, used 90 GB. After that point and excluded from some other "C" has returned to normal.
Observed protection system that it found itself changed, using configuration, approximately 98 GB, because usually, I leave an 8 GB for restore points.
The system creates the restore point, changes the amount of GB available, but when I try to use the "apply", have the following information:
"Could not create the scheduled task for the following reason: Access is denied 0x80070005" and unexpected error in the property page
Deactivating and reactivating system protection, same error. Make changes, but it has this error.
Used Combofix, Malwaribytes and other good scanners but nothing relevant was found. . . imaginos then it is not difficult for malware.
Was also used SFC, CHKDSK C: f / r /.
Please positioning.
