   • Information on how to delete the temporary update files can be found in respective section of FAQ 1599.
   • After deleting the temporary update files please try to update your AVG.

In case AVG can not be updated due to issues with connection to our update servers, please refer to FAQ 928.

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 1234.

If you receive error messages "Invalid update control CTF file" or "A .bin file is missing" during AVG update, please try to delete temporary files used during update. Please follow these steps to delete them:

• Run the AVG user interface (double-click the AVG 8.5 icon on your desktop).
• Open the Tools -> Advanced Settings... menu.
• Navigate to the Manage option in the Update branch.
• Press the Delete temporary update files button.
• Try to update AVG.

If the issue persists even after performing the steps above, please contact us using the Get Help Online option in AVG Help menu.

If you are using proxy server for connection into the Internet, you need to modify configuration of AVG update process this way:

Launch AVG User Interface -> from top menu "Tools" select "Advanced settings" option -> in the left navigation tree select "Update" -> "Proxy"
From the combo box menu located on the right hand side of this dialog select whether you want to:

• Use proxy
• Try connection using proxy and if it fails, connect directly

• Server – specify the server’s IP address or the name of the server
• Port – specify the number of the port that enables Internet access (by default, this number is set to 3128 but can be set differently – if you are not sure, contact your network administrator)

• From browser - the configuration will be read from your default internet browser (supported browsers being Internet Explorer, Firefox, Mozilla and Opera)
• From script - the configuration will be read from a downloaded script with the function returning the proxy address
• Autodetect - the configuration will be detected automatically directly from the proxy server

"Manage" option is accesible from the Advanced settings of the AVG program -> Update branch. It includes the following options for AVG update administration:

• Delete temporary update files
  When this button is pressed, all temporary update files (.bin) on your computer are deleted as well as the update control files (.ctf). This helps when the update control files are corrupted or when it is not possible to update the AVG program. Temporary update files are stored by default in C:\Documents and Settings\All Users\Application Data\avg8\update\download. After pressing of the "Delete temporary update files" button and confirming the deletion of the files, all files in this folder should be deleted.
• Revert virus database to previous version
  This button provides you with the option to return to the previous virus database. You can use this function in case that there is a false positive and it is needed to continue in using the detected file with AVG protection enabled. After pressing this button and confirming that you want to return to the previous version, AVG reverts back to the state before the last virus database update, so that a new false positive is not detected. When there is new virus database update published (and a false positive fixed) you can update directly to a new version without this false positive.

If you want to update AVG from local storage (CD, directory on HDD, USB Flash drive) you can do it this way:
