Firefox: Disable virus scan
You can switch off the virus scan integrated in Firefox, since most virus programs automatically check downloaded files for viruses. This prevents a double scan and saves resources.
How to switch off the virus scan
- In Firefox, navigate to the address line and enter the text "about: config". Confirm the security notice.
- Enter "Scan" in the "Search:" field.
- The first entry found is "browser.download.manager.scanWhenDone". Under "Value" this entry is set to "True".
- To set this entry to "False" and thus deactivate the scan, double-click on the entry.
