Which antivirus is your laptop/computer using ?
Are you happy with it ? Is it Free ?
Tell me an antivirus software that is free and is actually useful.
I am using Kaspersky Internet Security 2014 and am very happy with its security. I have also used the past versions of Kaspersky and they proved to be quiet reliable and secure for my computer.
I always used it free version and that works fine.
To use free version you need to register yourself on avast.
They ask few question and your free version is activated automatically or else they provide a key on your registered email.
But before going for registration be sure you've working internet connection.
