The figures are impressive, just are as "detection rate" graphs (for other products), but the overall product may not suite everyone. Also I think most suites are best designed for Windows XP, but not suited for Vista and 7 as much, and especially not Windows 8 (except some designed for Windows 8).
I did notice that Webroot does affect Youtube, hence why I like WD/MSE because it doesn't scan webpages.
