Hello,

 

I have a year old laptop that has been great, but about an hour ago it had an extremely bizarre slowdown after waking up from a 2 hour sleep/hibernation.  I could not get Task Manager to End Task of any of the two programs that were active, so I forced it to restart from C+A+D.  After restart it seemed to return to normal but I realized my only security/protection has been Windows Defender.  I started a full scan, which it is still currently doing.  The ETR keeps fluctuating while the file scanned number keeps increasing.  Right now it is over 1million files scanned.  Now the computer is only a year old, and I understand when it's scanning its scanning hidden and system files as well, but I find it surprising that I have this many files.

 

I did a quick google search to see if there was a way to have my computer's files counted and found this command line dir /s /a-d c:\  which I ran and it came up with a total file count of 646,729.  Why the discrepancy?  Is that command not including a large portion of files or is something else going on?

 

Thanks for your help!

I believe that command...only pertains to the C: partition...while a scan of the system would pertain to all partitions, if the AV/AM program is configured to scan a system with multiple partitions.

Yes, it's only the C: drive.

 

Another reason: you can only list files inside directories you have the rights to.
