What to do when encountering update errors in Bitdefender 2017

Update errors are usually caused by issues with the internet connection (the connection temporary failed, you are using a proxy, another firewall blocked the Bitdefender update, etc)

What to do in case you’re dealing with Bitdefender update errors:

Make sure Bitdefender is properly set up

1. Open Bitdefender and click on the Settings icon in the lower left side of the main interface.

2. Click on the Update tab.

3. Make sure the update settings are correctly set (the update location is the one displayed in the below image)

NOTE: Bitdefender Antivirus Plus doesn’t include the Firewall module

If you use another Firewall software, we recommend turning it off or uninstalling it (this also includes the Windows Firewall).

Should the situation still persist after following the above steps, please contact our Technical Support Department by replying to the open ticket you have with us (or create a new ticket) and send us the following logs.

We will also need the exact error message you receive. To find this, follow the steps below:

• Access the Settings menu by clicking on the Notifications icon in the lower left side.

• Select the Update tab.
