I bought 10 of this and half of them do not work property, this is a disposable product, do not waste your money and time.

I've used Panda antivirus software for years and installed it for my friends and clients. As a web designer, I want something to work well yet be unobtrusive. Norton and McAffee get their "code" into everything and it is hard to delete. Zone Alarm did just that everything was an alarm even after telling it not to. Panda works and is easy to install. You do have to delete your previous version of Panda using their uninstall and not Windows uninstall before putting in your new version. Also with the new Global Security 2011 you have to buy a 3 user license instead of a single but now days a lot of people have more than one computer. There are 3 in my household. It is well worth the investment.
