"evaluated 25 home user security products using their default settings" on Win 8.1 (64-bit).
Avira has improved dramatically in the last 6-7 months with its Protection Cloud feature. McAfee and Panda have also shown big improvements of late. But as long as you do not consider an AV as your ONLY anti-malware, then most of the AVs listed can be run in a layered defense. (okay I would think twice when choosing Ahn Lab or Windows Defender ).
I am running KIS on two machines as I receive free licenses from my Bank. KIS 2015 RC running as light as a feather here but I know some users have reported slowdowns.
I am running it with AppGuard and only have the KIS file and web scanners enabled; both systems are very fast with this setup with no slowdowns whatsoever. Now if Barclays offered F-Secure!
