Really good protection result this time, glad to see Avast is getting back, just the performance could be better. 
Yes, good results
Although I am surprised Avast! scores lower performance wise.
That was always one of its strong points.
Greetz, Red.
Yes previously avast always got full marks for performance.
Not sure about the test methodology, e.g. how tests were run and if NG, DeepScreeen, Hardened Mode, etc. would have been running. Whilst these would/should improve detection, but could come with a resource overhead.
The performance numbers are weird anyway. Like Bitdefender having 0s delay. Which is absolute horse manure unless if you perform some sort of aggressive whitelist skipping or caching. Or Comodo scoring 3s and yet it always makes my PC cringe in agony while it’s grinding a speedy Caviar Black HDD. avast! scores 4s and yet it feels by far the fastest. Not straight away on install, but after 2 days, it feels like I don’t have anything installed.
My guess that these tests won’t benefit from the Permanent or Transient Caching that a user would after a few days/scans, etc.
Same for MSE. People say how light it is and always go great performance scores, but for real world usage, it was never light and not even nearly lighter than avast!. And I still have a properly high end system.
If you ask me, important for users is how it behaves for real and not right after install. That doesn’t tell me anything. But when cache is properly built, that does tell me how AV actually behaves in day to day use.
I felt a difference in system response in Windows 10 as soon as Avast was running and Defender had been deactivated.
