Windows Security Center - AVG Turned Off
Your Windows Security Center reports that AVG is turned off even if AVG is running perfectly. The problem is common with free copies of AVG 8 on Windows, especially Vista. When you run an AVG scan, it runs normally, yet still you get the Security Center message.
There may be numerous reasons behind the problem. The following paragraphs discuss the causes and possible fixes for when your Windows Security Center incorrectly reports that AVG is turned off.
First, make sure that you have the most current updates installed. The Windows Security Center may be missing components that help it identify third-party antivirus and firewall software, and hence the message. Download the most recent updates and reboot. The Windows Security Center message should vanish.
If you are running Windows Vista, chances are your UAC settings are creating the problem. This sounds weird, but it is true. Open Control Panel and go to User Accounts to switch off UAC. After turning off UAC, close the Control Panel and run a good system cleaner. Open the Control Panel again and turn on the UAC. Reboot and you'll see the problem disappears. What happens is that when you turn off UAC, you remove some personalization. Once that personalization is gone, the problem- Windows Security Center reports AVG is turned off- is fixed.
One of the possible causes is a corrupt registry: an improper un-installation of the previous antivirus program you had. An improper uninstall may leave behind certain keys that clash with the new ones and thereby give an impression that there is no antivirus is installed. This also triggers the Windows Security Center message about AVG being turned off. If your previous antivirus was something other than AVG, check the Program Files folder to see if the folder for the previous antivirus is still present. If you upgraded or reinstalled AVG, I recommend a clean install again.
For a clean uninstall, remove AVG and delete all the leftover antivirus folders in your Program Files folder. Run a registry cleaner. There are many free yet good registry cleaners available on the Internet. Comodo and CCleaner are two best examples of such software. If you wish, you may backup the Windows registry before using your registry cleaner. After cleaning the registry and hard disk, reinstall AVG. This should solve the problem.
