yes have used AVG for many , many years without ever getting infected. In fact I am a AVG community vip. there are some downfalls on their program , but if you can live with those its a fairly good program.
I have acces to free licences for all products if I should need one , because I help them out. avg free does provide the same level of protection as internet secrurity ( av wise and without the firewall ofcourse ) add another free firewall of your choice and your good to go , no need for the premium package!
