This is a fantastic deal. I downloaded it with ease on both vista home premium over the trial version and xp homeover the avg free version. AVG does override your windows firewall and windows defender. In Vista I had to disable MS firewall and Defender upon prompting, giving you a choice of the firewall you want to use. In XP thee were less user choices presented during installation.

Three pieces x 2 years for avg internet security for under $35.? How is this getting a bad review at all? AVG trumps Norton, Mc Afee and K's suites and doesnt slow the machine down like they do. Less than 12 a machine for 2 years protection from a quality program. I don't understand why there isn't a run on this download.

I have been using AVG for 2 or 3 years. I had it on one computer, then I got it for a 2nd computer, and finally for a third computer. When it was time to renew, they put a big "pop up" on my screen saying LICENSE EXPIRED, RENEW NOW. But when I tried, they kept saying this license is invalid or has already been upgraded. So I had to go to the online chat. They found a different license # for me, and that let me get to the upgrade site, but they wanted me to buy a license for 3 computers. I only want one. Another trip to the online chat with Customer Service. "I'll have someone email you a price," they said. After 2 tries I got an email that said you're offered a chance to renew "offline" -- what? am I supposed to send my credit card in an email? The whole thing is clunky and suspicious. Can't they even protect their own website? Why the need to have such a round-about renewal process? It makes me wonder if their software will protect me.

AVG continues to stand out as a great Internet Security package, extremely user-friendly and price conscious. This year a few have surpassed it in standardized efficacy tests, but not by much. For the price, this is my recommendation for friends who don't want to manage multiple free products and don't have a fortune to spend on AV products. It's a great bang for the buck.

The download however, works OK for most but could certainly be better. I bought this for my mother-in-law whose primary computer still runs Windows 2000 Pro. THE AMAZON DOWNLOAD SYSTEM WILL ONLY WORK IN WINDOWS XP & NEWER! Running it in XP, it seems to work fine, though it requires a download and installation of their program before the purchased download can begin. It's clunky but effective, and the only reason I marked this product down to 4-stars (it is after all a download-only version). The mark-down is through no fault of AVG however, simply the crude download process from Amazon.
