Protected PC is important if we use internet or even if we don’t use internet on pc but we put in different CD/DVD or USB drives.
Latest version AVG Antivirus Free version 2013 is one of the best free home use antivirus application. This version support Windows 8 too, but it’s not enough user friendly for touch screen use. Updates runs automatic, so user doesn’t have to take care of this.
Good advice:
