Other than one minor gripe (below) I have always found AVG to be very trustworthy and reliable.They have kept my online presence safe for several years now.My only complaint would be that when they want you to take out a pay-to-use service, you have to be careful if you are only using the basic service and don't want to upgrade.Upgrades (to me, at least) look like updates to your current service. It's only when you've clicked link that you find it's a pay-to-use service.
