AVG Internet Security is simple to install- All you have to do is load the CD, follow the links to register and key in the emailed password- and runs unobtrusively in the background. Much as with the other AVG products I have used, this appears to do what it says on the tin.It is difficult to see why you would opt for their Anti Virus program ( AVG Anti Virus 2013: 2 User - 2 Year License (PC) over this for any reason, other than the cost (This licence is for only one year. Anti Virus is two). It appears to offer more protection than their basic package (which is ALSO available free with little noticeable difference in offerings), Including, among other things, a Firewall, which I am told is a good thing. With years of virus free computing using AVG free, I am confident in their products and have every reason to recommend this.
