Security software and TurboTax

SOLVEDby TurboTax88Updated December 13, 2023

Firewall and virus- or spyware-protection programs protect your computer from potential harm by guarding against unauthorized actions by programs on your computer.

However, if your firewall blocks TurboTax software's internet access you won't be able to e-file, download state programs, or get the latest program updates.

In some cases, security software may misinterpret the actions of legitimate programs (like TurboTax). The security software would then block the program's internet access.

To prevent or resolve these conflicts:

  1. Download the latest updates from your software's support site.
  2. Adjust the settings or rules on your security software to allow selected programs (like TurboTax) to install and function as intended.

Most firewalls ask you for permission when an "unknown" program attempts to connect to the Internet. If you previously told your firewall to block TurboTax, your firewall will continue to do so until you add it to the list of allowed programs. In some cases, you may need to add TurboTax ports and addresses to the firewall's list.

Advanced users running Windows can manually configure firewall software by adding these processes as exceptions to Windows Firewall or other installed firewall software:

  • C:/Program Files/Common Files/IntuitUpdate Service/IntuitUpdater.exe
  • C:/Program Files/Common Files/IntuitUpdate Service/IntuitUpdateService.exe

These resources may help you resolve issues with your particular firewall. Remember to always run the latest version of your firewall program and keep it fully up-to-date.
