Hi All Just got myself a brand new Surface 3 today, part of an early fathers day present and a also a gift from my lovely wife .(I'm very excited and happy lol) Now its only the base model with 2gb ram and 64gb ssd but that's all we could stretch to. What I want to know is are you using an Antivirus program/software as this is more like a laptop as it can use normal software and not locked like RT was. If you are using Antivirus which one and does it impact on the speed and usability of the Surface 3. I ask this as I know some AV software can be pretty power hungry and don't want to bogs my Surface 3 down. Thanks so much for your time and trouble. Kindest Regards James..
