If you got Firefox from mozilla.org whether stub or full setup from https://www.mozilla.org/en-US/firefox/all/ then there should be no form of viruses, trojans, malware, ads or such. No version of Firefox for Windows, Mac OSX or Linux has with the exception of a certain locale contrib build like eleven years ago as it was not until Firefox got to version 1.0 that there were other official language builds besides en-US then.

Some antivirus applications give false positives with Firefox related stuff especially depending on timing of Firefox release and new definitions update, especially with the stub installer. There was a post a couple days ago about McAfee giving a false positive with the stub installer of Firefox 31.0. If it was true that Firefox 31.0 for Windows came with a virus it would very likely be a active topic here and on tech sites.

I see that you have Firefox 6 installed. You're way overdue for an upgrade. If you installed Firefox 31 from the official site, you shouldn't have any problems. Mozilla downloads are clean
