[. . . ] Ignore Faulty Conditions In the Ignore faulty components conditions dialog you can tick those components that you do not want to get informed about: By default, no component is selected in this list. It means that if any component get to an error status, you will be informed about it immediately via: · system tray icon - while all parts of AVG are working properly, the icon is displayed in four colors; however, if an error occurs, the icon appears with a yellow exclamation mark, · text description of the existing problem in the Security Status Info section of the AVG main window There might be a situation that for some reason you need to switch a component off temporarily (this is not recommended, you should try to keep all components A V G A nti- V irus Free E dition 2 0 1 1 © 2 0 1 0 C opyright A V G T ec hnologies C Z, s . r. o. A ll rights res erved. 61 permanently on and in default configuration, but it may be happen). In that case the system tray icon automatically reports the component's error status. However, in this very case we cannot talk about an actual error since you have deliberately induced it yourself, and you are aware of the potential risk. At the same time, once being displayed in grey color, the icon cannot actually report any possible further error that might appear. For this situation, within the above dialog you can select components that may be in an error state (or switched off) and you do not wish to get informed about it. The same option of Ignoring component state is also available for specific components directly from the components overview in the AVG main window. 9. 4. Virus Vault The Virus Vault maintenance dialog allows you to define several parameters regarding the administration of objects stored in the Virus Vault: · Limit Virus Vault size - use the slider to set up the maximum size of the Virus Vault. The size is specified proportionally compared to the size of your local disk. · Automatic file deletion - in this section define the maximum length of time that objects should be stored in the Virus Vault (Delete files older than . . . days), and the maximum number of files to be stored in the Virus Vault ( A V G A nti- V irus Free E dition 2 0 1 1 © 2 0 1 0 C opyright A V G T ec hnologies C Z, s . r. o. A ll rights res erved. 62 Maximum number of files to be stored) 9. 5. PUP Exceptions AVG Anti-Virus Free Edition 2011 is able to analyze and detect executable applications or DLL libraries that could be potentially unwanted within the system. In some cases the user may wish to keep certain unwanted programs on the computer ( programs that were installed on purpose). Such adware might be detected and reported by AVG as a potentially unwanted program. If you wish to keep such a program on your computer, you can define it as a potentially unwanted program exception: The Potentially Unwanted Programs Exceptions dialog displays a list of already defined and currently valid exceptions from potentially unwanted programs. The following information can be found in the list for every single exception: · File - provides the name of the respective application · File Path - shows the way to the application's location · Checksum - displays the unique 'signature' of the chosen file. This checksum is an automatically generated string of characters, which allows AVG to unequivocally distinguish the chosen file from other files. The checksum is A V G A nti- V irus Free E dition 2 0 1 1 © 2 0 1 0 C opyright A V G T ec hnologies C Z, s . r. o.

Control buttons · Edit - opens an editing dialog (identical with the dialog for a new exception definition, see below) of an already defined exception where you can change the exception's parameters · Remove - deletes the selected item from the list of exceptions · Add exception - open an editing dialog where you can define parameters of the new exception to be created: o File - type the full path to the file that you want to mark as an exception o Checksum - displays the unique 'signature' of the chosen file. This checksum is an automatically generated string of characters, which allows AVG to unequivocally distinguish the chosen file from other files. [. . . ] Note: If a time coincidence of a scheduled program update and scheduled scan occurs, the update process is of higher priority and the scan will get interrupted. 11. 2. Update Types You can distinguish between two types of update: · On demand update is an immediate AVG update that can be performed any time the need arises. · Scheduled update - within AVG it is also possible to pre-set an update plan. The planned update is then performed periodically according to the setup configuration. [. . . ]
