In case you have changed Dial-Up connection to Broadband, it is required to change also the AVG configuration to be able to update.

You can set this the following way: 

• Open the AVG program. 
• Select the Advanced Settings option from the Tools menu.
• Navigate to the Update branch -> Dial-up.
• Untick the Use dial-up connections option.  
• Confirm changes by clicking on the OK button.

Now you will be able to perform an update using your new Internet connection.

Note:
In case the new (broadband) connection is done using DSL modem, which is connected via USB interface directly to your computer, it is needed to keep the original dial-up settings.

AVG automatically updates on a regular basis, making sure that your protection is always up-to-date. Although it is not necessary, you can also update your AVG program manually at any time.

There are several ways to update the AVG program manually:

Open the AVG program (double-click the AVG icon on your desktop or double-click the AVG icon in the system tray next to the clock).

• Click the Update now button in the left part of the AVG program.
• Or on the Tools menu, click Update.

It is also possible to update AVG by right-clicking the AVG icon in the system tray next to the clock and selecting the Update now option.

After you install AVG, the First Run Wizard asks you (among others) how often you wish to update your AVG. The available options are Every 4 hours, or Every day. Keeping your AVG up-to-date is crucial to ensure that all newly discovered viruses will be detected as soon as possible.

Since AVG updates are not released according to any fixed schedule but rather in reaction to amount and severity of new threats, it is recommended to check for new updates at least once a day. Checking every 4 hours will guarantee that your AVG Virus base is kept up-to-date also during the day.

For more information on how to set the AVG update schedule, please see FAQ 2149.
