Adding Backblaze to Bitdefender's Allowances

It is not uncommon for security programs such as Bitdefender 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 add a rule inside Bitdefender to allow the Backblaze application to run. 


1. Open the Bitdefender application, and select Protection from the left-hand menu. Then click on Settings under FIREWALL. 


2. Next, click on Add rule.


3. Click the BROWSE button.


4. Select the file named bztransmit.exe or bztransmit64.exe and click OK.

  • 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 and 10 64-bit, it's in C:\Program Files (x86)\Backblaze\bztransmit64.exe

(If you don't know if you're running a 32-bit or 64-bit version of Windows, choose both bztransmit.exe and bztransmit64.exe separately, and perform steps 3 and 4 twice, once for bztransmit.exe, and again for bztransmit64.exe)


5. Ensure that the check next to Permission is on (blue) and click OK.


6. Repeat this for files bztrans_thread00 - bztrans_thread19

7. Bitdefender will advise you to reboot your machine for the new changes to take effect. 


Bitdefender should no longer block the Backblaze program from running properly.
