Background

In Firefox 3, if a Windows user has an antivirus program installed, it is launched to scan files when they finish downloading. During testing of the feature, concerns about delays and double-scanning files surfaced. As a result, this preferenceâ€”controlling whether the virus scan is automatically triggeredâ€”was created.

Starting in Firefox 3.7 (3.7a3pre nightly builds since 2010-03-06) this preference also controls whether or not the Windows security policy checks are applied for downloading and launching executable files. [3] [4]

Possible values and their effects

[edit]

True

Scan files for viruses when they finish downloading. Starting in Firefox 3.7, also apply Windows security policy checks. (Default)

[edit]

False

Do not scan downloads for viruses. Starting in Firefox 3.7, also bypass Windows security policy checks.

Caveats

In Firefox 3.6 and below (at time of writing) this preference is only used for scanning completed downloads and only has an effect if you have antivirus software installed and are running Windows.
Starting in Firefox 3.7 (3.7a3pre nightly builds since 2010-03-06) this preference, when set to false, also bypasses Windows security policy checks. Note: Starting in Firefox 3.6, browser.download.manager.skipWinSecurityPolicyChecks is no longer used.
