In the process of building a new PC - installing Windows Pro 8.1 64-bit OS (8 GB RAM). Which Internet Security software is best in terms of: (1) identifying and eliminating malware; (2) firewall; (3) resource use; (4) compatibility with OS; 5) ease of use in general. Reviews in general list BitDefender & Kaspersky as #1 & #2 pretty much generally but also heard horror stories about each and want to get REAL PEOPLE with REAL EXPERIENCE! I really want a complete suite of tools whether it be one program or several it does not matter to me - though I am the only user of this pc so won't need site blocking. Thanks for your help!
