Funny, even my computer said... to down load their crap... "may harm your computer". The last two scams like this one, [same" cyberdefender corp"] I put on a fresh reload computer to test its claims with no problems or web usage on the computer, and it still showed some 300 "errors" to which the known company "NORTON" Windoctor said the computer was fine, and my Legit AV soft ware keeps showing "no problems". I have repaired dozens of computers this year that made this mistake, and then using a LEGIT AV company fixed the actual problems [mostly Cybers malware] and yes it costs around the same price, but over all it costs a far less than Cyberdefender because it actually fixes the real problems, including their installation.
