All I can say is "terrible". Let's start with the bad, since that's basically what this product is.

This product uses less room on my computer than the other anti virus- malware products. It's fairly self managing; just set your options and let it go on its own. The program will tell you verbally when it has updated (optional) so you can keep surfing, playing, working without interruption. I highly recommend this product. There is a free version as well; but of course the perks are in the paid for edition. After having the free Avast, I just had to upgrade to the paid version because I was so pleased with the product. The extra protection from the freeware is, in my mind, more than worth the small amount for the paid version. It is not expensive yet It is worth every penny and more for the peace of mind. Avast! Internet Security is my protection of choice and I highly recommend it.

I take a number of different products for keeping healthy but I have never had one make such a dramatic impact in such a short time...it has been simply astonishing.
