Tutorial: Virus Scans & System Cleanup (PC)

1. Running a Virus Scan with Windows Defender (Microsoft Defender Antivirus)

Windows 10/11:

1. Click the Start Menu and type Windows Security. Open it.

2. In the Windows Security window, click Virus & threat protection.

3. Under Current threats, click Quick Scan to immediately scan important areas of your computer.

4. For a deeper scan:

   • Click Scan options under the Current threats section.

   • Choose Full Scan and click Scan Now. (This may take 1-2 hours.)

Notes:

• Ensure that Windows is fully updated by checking Windows Update.

• Threats found will be quarantined automatically or prompt you for action.

Fix the "Virus Scan Failed" download error in Google Chrome, and the "Couldn't Download Virus Scan Failed" error in Microsoft Edge

1. Locate the following registry subkeys:
   \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Attachments
2. If you do not see the "Attachments" subkey, create it by right-clicking on "Policies", selecting "New", then clicking "Key", and then typing "Attachments" as the key name.
3. Right-click "Attachments", select "New", and then click "DWORD (32-bit) Value".
4. Type "ScanWithAntiVirus" as the value name, and then press Enter.
5. Right-click the new "ScanWithAntiVirus" DWORD value, and then click "Modify".
6. In the "Value data" box, type 1, and then click OK.
7. Exit the Registry Editor.
8. Restart your computer, and then log back into Windows to have the registry change take effect!

The download error(s) should be now resolved in both Google Chrome and Microsft Edge!
