FAQ

When updating your AVG to the latest program version, the update process may need to be started twice and the update may ask you to restart your computer. The full update procedure is the following:

1. When you click "Update now" or the scheduled update is started, main part of the update is downloaded and applied.
2. The Update Manager in your AVG will report that new update files are available. Your AVG will be fully functional at this point, but not fully updated yet.
   
3. When the update process is started again, the update will be completed.
4. A computer restart will be required, unless your operating system is Windows Vista. Please note that some AVG components will not work until you restart your computer.

After the restart, AVG will be fully functional and updated to the latest available program version. Please refer to FAQ 1432 for the list of changes in the latest AVG program update.

LinkScanner is a new security component. It is part of all AVG commercial editions. You can find it in the AVG user interface and you can change its configuration there as well.
You can find 3 options when you open the LinkScanner component:

1. Enable AVG Search-Shield
   It checks the SEARCHED (using Yahoo, Google or MSN) web pages content.
2. Enable AVG Active Surf-Shield
   It checks the VISITED web pages content while the web page is loading.
3. Enable reporting of exploited websites to AVG
   This service sends a report about found insecure web page to our lab for detailed analysis.

The LinkScanner component can be connected with the AVG Security Toolbar, which is part of Internet Explorer or Mozilla Firefox Internet browsers. You can read more about AVG Security Toolbarin this FAQ.

If you look into the Windows Task Manager, tab Processes, you can see how much memory is used by each AVG process. This number can range from single to tens of megabytes, depending on the process (e.g. Resident Shield has loaded the whole virus base, plus the data it is currently scanning). However, it is not possible to simply add up the memory consumption of each AVG process to get the overall memory usage of AVG. Some of the allocated memory displayed for each AVG process is in fact shared between all processes. If for example 3 processes are using 10 MB of shared memory, they will be still displayed as 3 separate processes, consuming 30 MB combined, which is not true.

In case you are experiencing a major slowdown while AVG test is running, or, on the other hand, AVG is not scanning fast enough, please try to adjust the scan performance, which is displayed in the bottom part of the AVG User Interface - "Computer scanner" - currently running scan.

If you are using Windows Vista and your computer or Internet connection is working much slower than before installation of AVG, please try to install the Windows Update Windows update KB929547. 

The AVG Security Toolbar is a new tool which works together with the LinkScanner component and checks search results of the supported Internet search engines (Yahoo!, Google, MSN).

 

This tool is available in all editions of AVG 8.0. If you select to install the toolbar during the installation of AVG, it will be added into your Internet Explorer and/or Mozilla Firefox. Please let us inform you that in case you are using some alternative Internet browser instead of Internet Explorer, (e.g Avant Browser) you can meet unexpected behaviour.

 

The AVG Security Toolbar can be used to control the LinkScanner functions and to adjust its behavior, and to update your AVG in case new updates are available. There are some another functions included in AVG Security Toolbar.

 

If you decide that you do not wish to use the toolbar, you can either skip its installation during the AVG installation process, or disable it manually in your Internet browser:

1. Internet Explorer

• use the mouse right-click on the toolbar and check-off the AVGTOOLBAR option in the list

 

2. Mozilla Firefox

• Tools menu -> Add-ons, find the AVG Security Toolbar here and click on the Disable button

Disabling or uninstalling the AVG Security Toolbar has no negative effect on the level of security provided by LinkScanner component. The only consequence of missing toolbar is an absence of some of the options, and less verbose information about the threats found by the LinkScanner component. The main settings of the LinkScanner component can be still configured in AVG User Interface.

 

More information about AVG Security Toolbar here.
You can find more information about the AVG LinkScanner component in this FAQ.

 

Note:
AVG Toolbar contains also a Yahoo! search box, which is an integral part of the toolbar and can not be removed separately.

There's also a possibility to set up Yahoo! as a default search engine in your Internet browser while running the AVG First Run Wizard. However that is not connected with AVG Security Toolbar anyhow.

On some computers with Windows Vista, opening of websites or accessing network resources can be greatly slowed down when AVG WebShield is active. This behavior is in fact caused by a problem in one of the Windows network drivers, and can be fixed by installing the Windows update KB929547:

• 32bit platform
  Windows update KB929547
• 64bit platform
  Windows update KB929547
