Since I can't know what apps you installed or what malware is on this PC, 2 ideas.
1. Run CHKDSK /F /R /X on all disk drives.
2. Scan and remove malware with Grif's help at http://www.cnet.com/forums/discussions/how-to-remove-pup-option-603542/#post-f742c795-5881-433b-a29b-6d758efe5cd3
Randomly show this error "Attribute utility has stopped working"
How can I solve this issue?
Os-win10 pro 64bit build 1703.
