Windows 10: Is it safe to let a full system scan run overnight?

So i'm suspecting there's some kinda malware on my computer and I wanna run a anti virus full system scan. Would it be safe to let a full system scan run overnight while I sleep? Power settings are set to never for when the computer will sleep after certain time of inactivity and my AV will shutdown my computer after scan ends.

:)

 

New FF - passwords

Hi:

If that setting is already enabled, then I suggest as the next troubleshooting step might be Mozilla Safe Mode (not to be confused with Windows Safe Mode)):

• Please report back and let us know the outcome, as it will dictate the next steps.
• Also: please tell us what AV/AM/firewall programs are you running on this system?

Thanks,

Defender getting turned off during overnight full scan. (Windows 10)

Hello,

Welcome to Microsoft Community.

I would like to ask you:

• What registry script did you use?
• What all troubleshooting steps have you tried so far?

I would suggest you to try the following methods and check if it helps.

Method 1

This issue may happen due to system file corruption. I suggest you to run System file checker. System File checker (SFC) scan is done to check if there are any corrupted system files that could be causing this issue. Kindly follow
the below given steps:

• 
  Press Windows key + X, select
  Command prompt (Admin) to bring up elevated Command prompt.
  
• 
  In Command prompt type
  sfc/scannow and press enter.
  
• 
  Restart the computer.
  
  If no corrupted system files were found in the previous state, then I suggest you to try the following steps:
  

• 
  Open command prompt by pressing Windows key + X and selecting “Command prompt admin”.
  
• 
  In command prompt, type the following commands and press Enter after each command:
  
  DISM.exe /Online /Cleanup-image /Scanhealth
  
  DISM.exe /Online /Cleanup-image /Restorehealth
  

• 
  Close the command prompt and restart the PC and check if it works.
  

Method 2

Please follow the below steps to set the right registry entry and check if it helps.

• Press Win key + R. This will open Run.
• Type "regedit" and hit enter.
• Navigate to these keys:
  
  HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender
  
  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender
• Change value of 'DisableAntiSpyware' and 'DisableAntiVirus' from '0' to '1'.
• After changing the values go to 'C:\Program Files\Windows Defender' and open 'MSASCui.exe' file.

To do so: Important this section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For
added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft
Knowledge Base:

How to back up and restore the registry in Windows

If the issue persists, I would suggest you to run a system restore and restore the system to a previous date when it was working fine.

• Open Start menu.
• Type System Restore and hit enter.
• Follow the prompts and select a restore point when your PC was working fine.

Disclaimer: When you use System Restore to restore the computer to a previous state, programs and updates that you installed are removed.

Hope this information was helpful.
