Update Settings
Note
For more details regarding the Update module check the description of the “Update Module”.
Automatic Update

In this section you can see update-related information and perform updates.
Important
To be protected against the latest threats keep the Automatic Update enabled.
If you are connected to the Internet through broadband or DSL, BitDefender takes care of this itself. It checks for updates when you turn on your computer and every hour after that.
If an update was detected, depending on the options set in the Automatic update options section, you will be asked to confirm the update or the update will be made automatically.
The automatic update can also be done anytime you want by clicking
Update Now. This update is also known as Update by user request.
The Update module will connect to the BitDefender update server and will verify if any update is available. If an update was detected, depending on the options set in the Manual update settings section, you will be asked to confirm the update or the update will be made automatically.
Important
It may be necessary to restart the computer when you have completed the update. We recommend doing it as soon as possible.
Note
If you are connected to the Internet through a dial-up connection, then it's a good idea to make it a regular habit to update BitDefender by user request.
You can get the malware signatures of your BitDefender by clicking
Show Virus List. A HTML file that contains all the available signatures will be created. Click again
Show Virus List to see the list. You can search through the database for a specific malware signature or click BitDefender Virus List to go to the online BitDefender signature database.
Manual Update
This method allows installing the latest virus definitions. To install a product upgrade of the latest version use the Automatic update.
Important
Use the manual update when the automatic update can not be performed or when the computer is not connected to the Internet.
There are 2 ways to perform the manual update:
- with weekly.exe file;
- with zip archives.
Manual Update with weekly.exe
The update package weekly.exe is released every Friday and it includes all the virus definitions and scan engines updates available up to the release date.
To update BitDefender using weekly.exe, follow the next steps:
- Download weekly.exe and save it locally on your hard disk.
- Locate the downloaded file and double-click it to launch the update wizard.

Manual Update with zip archives
There are two zip archives on the update server, containing the updates of the scanning engines and virus signatures: cumulative.zip and daily.zip.
- cumulative.zip is released every week on Monday and it includes all the virus definitions and scan engines updates up to the release date.
- daily.zip is released each day and it includes all the virus definitions and scan engines updates since the last cumulative and up to the current date.
BitDefender uses a service-based architecture. Because of this the procedure to replace the virus definitions is different depending on the operating system:
- Windows 2000, Windows XP, Windows Vista.
- Windows 2000, Windows XP, Windows Vista
Steps to be followed:
- Download the appropriate update. If it is Monday, please download the cumulative.zip and save it somewhere on your disk when prompted. Otherwise please download the daily.zip and save it on your disk. If this is the first time you update using the manual updates, please download the both archives.
