Adding Backblaze to Windows Defender Allowances

Emily Emily

It is not uncommon for security programs such as Windows Defender to mistakenly flag the Backblaze program as malware. As a result, our program may not be able to be installed or the program may malfunction. To fix this you can whitelist the Backblaze application inside Windows Defender, which will prevent Windows Defender from blocking our program. 

 

1. Open up Windows  Defender Security Center, and select Firewall & network  protection from the left-hand menu. Under Public network click on Allow an app through firewall.

4. Locate the file named bztransmit.exe or bztransmit64.exe (Note the file path circled in the image below.)

Navigate to the location of bztransmit and choose the right version for your OS and click Open.

  • For Windows XP, it's in C:\Program Files\Backblaze\bztransmit.exe
  • For Windows Vista, 7, 8 and 10 32-bit, it's in C:\Program Files\Backblaze\bztransmit.exe
  • For Windows Vista, 7, 8 ,10 64-bit, and 11 it's in C:\Program Files (x86)\Backblaze\bztransmit64.exe
