Hi friends, I have purchased a New Laptop, I would like to know which is the best antivirus for Laptop.
I recommend Microsoft Security Essentials. It is free, and can be downloaded from here
Your laptop probably came with a trial version of Norton, Macafee or one of the other 'big' antivirus programmes. It is very important that you uninstall this from the laptop before installing MSE or any other antivirus package. (Uninstall it via the add/remove programmes feature in the Control Panel).
