I've noticed this too, it's light and pretty decent now.Great performance. Just one thing to point out, McAfee is very light. In fact, it is one of the lightest security products nowadays. I know it used to be a resource hog but that's not the case anymore.
I have Bullguard Internet Security installed on every gaming device at home. Its system impact is trivial. Regarding McAfee's Micro AV, though I have not used it, I do not think it will be impressive. Their other offerings (Internet Security and Total Security) offer great protection and they are very very light. McAfee has improved a lot.I wish someone would do a Gamer security test, since it's using their cloud Micro AV and no one seems to know if that offers comparable protection.
Yeah, I forgot about that though you have the option to show results for any search engine and change it back to what you want.WebAdvisor relies on yahoo search engine (or only a specific, limited # of search engines) IIRC so your browsing history is up for grabs. I don't know if it's changed but that's how it was a couple of years ago when I used it.
