most of them are malware or malware waiting to happen.
there detection isnt great, often miss diagnosing which drivers need updating. often with the malware 1s it will diagnose just to get you to download an adjusted driver.
truth is laptops dont need that much updating anyway. 1s you have the drivers you need. its very rare to see new versions for laptops.
if you game on a laptop then your keep your gfx up to date and dont bother with system drivers if you dont have issues. if you do just go to the lappy manufacturers site and you will get all the drivers you need for that system.
