I usually use Acronis True Image 2010 for protection against threats via internet or any alterations youve accidenty or deliberatetly caused on your Operating system or sofware. This is an awesome program and I highly recommended.
Its gotta a “try and decide” special features that allows you to save changes or not when altering any harmfull software and changes to your Operating system.
You can either create backup, non stop backup, a bootable disk of your current Operating system, or an image of your HD. Its perfect for protecting your hardware against Internet threats and the less knowledgeable users on your network.
