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.
