== Issue == I have another kind of problem with Firefox == Description == I have just confirmed with McAffee that Scriptff.dll is not a McAffee file, but it is a Mozilla file The path under properties is: Program Files x86\ Mozilla Firefox\components\Scriptff.dll I have deleted a backup on an external drive, but this Scriptff.dll remains. Whenever I try to delete it, I am told I need permission to do this. I do have administrator rights. How can I delete this file. == I only became aware of the problem after deleting the backup == == Troubleshooting information == Someone in this forum had replied earlier with the advice that it was a McAfee file, but the McAfee support person looked at the file and saw under properties that it was under Mozilla. == Firefox version == 3.6.6 == Operating system == Windows Vista == User Agent == Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.6) Gecko/20100625 Firefox/3.6.6 GTB7.1 ( .NET CLR 3.5.30729; .NET4.0C) == Plugins installed == *-1.7.0069.2 *The QuickTime Plugin allows you to view a wide variety of multimedia content in Web pages.
