sfc \scannow
restart after finishing the test
if there were errors, do it once again
Do a check disk from command prompt in the same manner:
type:
CHKDSK C: /F /R
Click OK to start test by restarting the system
Do a full malware scan- use MalwareBytes Free version - download & update it to latest version, then do the scan.
