I picked up a Lenovo Flex 15 lap top and it has McAfee security installed. Being brand new to Win8/8.1 I don't now if this is a resource hog or not. I run MSE with MBAM and SASW on my Win7 machines. This McAfee appears to run pretty good, but I'm just starting to learn W8.1, so far I like it, it's sure is fast.

You long time W8 users, are you using Defender/MSE or non oem security?

PS: What's a good AV for Win8 tablet? I bought a Dell Venue 8 pro also. My trusty Kindle is going to gather dust now.
