Double-click AVG Anti-Virus icon on your Windows desktop taskbar, or find and click AVG Free User Interface program shortcut under your Windows Start menu to open dialog below.
First lets make sure AVG Anti-Virus, Anti-Spyware and License components are all green and Active.
Start by opening Resident Shield component - this component is critically important as it's your first line of defense against viruses and spyware getting into your computer through the internet, email or external storage devices. Make sure Resident Shield is Active and set to Remove all threats automatically.
If absolutely sure in your own ability to control exceptions and false positives set Resident Shield to ask me before removing threats instead of removing threats automatically, and add exceptions if necessary. Save changes when done.
Lets now open Update Manager component making sure it's Active and set to Start Automatic Updates at least once every 24 hours (the only available choice in AVG free edition). In the example below AVG will check for updates every morning at 5 AM... Save changes when done.
Now we can check Link Scanner and E-mail Scanner components and safely select all options there. Basic setup is now complete... Confirm changes if any (or cancel to exit to main menu).
It's time to fine-tune AVG with advanced settings. Click Tools Menu, Advanced Settings to open advanced AVG settings dialog below.
Lets scroll down to Resident Shield menu on the left and make sure our Resident Shield is enabled, as well as Scan Boot Sector of removable media, Use Heuristics and Auto-heal selected as well. Other options in this section are optional - especially
Next we step down to Resident Shield Advanced Settings and select Scan All Files option instead of default
Last option lets us to add Exceptions for AVG to bypass active monitoring of selected folders on the computer. In our case we instructed AVG not to monitor one of the gaming directories where game would crash with connectivity related errors - it's a perfect example of a situation where AVG resident shield may block, or interfere with legitimate, often proprietary software installations. Be ready to access this area should you notice abnormal operation or crashing of certain software titles after deployment of AVG Anti-Virus on your computer.
Next lets tune AVG scheduled and on-demand scans settings...
We want to make sure Scan whole computer, Shell extension scan and Scan specific files and folders set to Automatically Heal / Remove Infection, Scan Inside Archives, Use heuristics and Scan system environment. Deselect
Also, make sure Removable device scan is also enabled (last Scans selection) and critical options are set there as well - we have seen a lot of nasty viruses coming form USB flash drives, and memory cards. This component is no longer optional in our opinion!
Next component is Schedules...
If your computer stays ON all the time it's a good idea to schedule automatic sweeps while you are away or sleeping. As an example we've scheduled our complete computer scan to run nightly at 2 AM, using the same general scan behavior we used for manual on-demand scans (How to scan and What to scan tabs). Schedule here is really flexible and can be easily set to your own preference.
At this point we have optimized critical AVG Resident Shield and Scanning components to provide us with the best real-time protection possible. The rest of the components in the advanced settings dialog can be left alone at their installation defaults (providing they are set up correctly by initial AVG installation and function properly).
We found AVG 8.x Anti-Virus (free edition) to be very effective antivirus / antispyware product, providing it's installed and configured correctly. It's also very simple to understand and configure, light and easy on your computer resources.
