BitDefender is blocking all downloads, including Apple Update Software. It will get to 99% and then fail. I have tried turning everything off on BitDefender, but it stills blocks it when it gets to the scanning part of the download. If I totally uninstall BitDefender, it works fine. I have tried using the Uninstall BitDefender Tool on the website, and again, it works fine without BitDefender running. But as soon as I reinstall BitDefender 2015 IS (downloaded from website, so I have current edition), it will immediately start blocking all downloads again.
I've also reset the standard firewall settings when BitDefender was uninstalled (just in case something crazy was linked), and also reset the Firewall settings in BitDefender Firewall. Again, everything works perfect each time I uninstall BitDefender, with standard Uninstall or with the BitDefender Uninstall Tool that I downloaded from website.
Any ideas would be greatly appreciated!
