Firefox crashes when attempting to perform a virus scan

With some antivirus programs, the virus scan after files are downloaded may cause Firefox to crash. You can disable virus scanning in Firefox with the following steps:

  1. In the address bar, type about:config and press EnterReturn.

    • The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!I accept the risk! to continue to the about:config page.
  2. Locate the browser.download.manager.scanWhenDone preference and double click it to change the value to false.
