Problems with AVG security software are not common, but they do happen occasionally and you might need to either fix the program or remove it. Once it is deleted from the system, a fresh new copy can be downloaded and installed. That should be OK.
How to repair AVG
The first thing to try is to repair the AVG program installation. Open the Control Panel, set the view to small icons, and then click Programs and Features.
There may be two items called AVG and AVG Protection. The first is AVG Zen, which is the control centre where you can view the status of various AVG security programs, add computers, install more security and so on. Ignore this.
Select AVG Protection, which is the antivirus, and then click Change. Double clicking AVG Protection works too.
There are two options and AVG can either be repaired or uninstalled. Click the Repair button and follow the instructions. (There’s nothing to it really.)
Restart Windows when it has finished and see if this has fixed whatever problem you had.
If the problem is still there, go to AVG Download Center and download AVG Remover.
It is saved to the Downloads folder, so open Explorer, open Downloads and double click the AVG_Remover.exe file.
The PC will restart and when the desktop reappears, all AVG software is gone. Now you can go to the AVG website and download a fresh copy of the software and install it.
If you are using the paid version of an AVG product, you might be prompted for the license information. This is in the email receipt when you bought the product.
Stop the ads in AVG from popping up
If AVG is displaying too many adverts, it can be irritating. There is a way to reduce the frequency that they appear.
Open the AVG window and select Options, then Advanced settings.
Select Appearance and find the section Set Maximum Frequency of in-app offers. Select the maximum duration. This will be once every three days for the AVG Antivirus Free, but if you have bought a licensed Pro version you can select the Never option and never see another ad.
