Query: This product is a joke.

This did not catch the virus that infected my system before it got in and could not locate it with it's Virus Scan after infection. I have turned it off because it's such a resource hog and I rely on the free protection that comes with my browser.I also could not get the rebate that was promoted when I purchased the product even though I provided the requested documentation and their customer service and help facilities are of little, if any, use. I advise everyone to stay away from this company and their products.
