If you use AVG free then you will no doubt have noticed the popup screens that have been appearing in the last week or two (as below)
Once again, we are being led by the nose to “upgrade” to a paid version of a product that is perfectly adequate in its free version. They highlight the “Recommended Protection” option in orange, hoping you’ll click on this button. To install the latest free version, however, you should click on the “Update Your Free Protection” button.
It seems to me that the free version is still perfectly adequate and I myself am going to continue to use it.
