Nox is a pretty safe emulator from what I know. Make sure you always have two step authentication on your accounts.

BlueStacks

I like Nox ... but be aware. It has problems with having Microsoft's HyperV installed on a system and may crash. But in case you don't use it and deinstall this feature, all should be fine.

Been using Blue Stacks for a while now , never had any issue with it

The android SDK's emulator should be as safe as it gets, but you can't really play on it if that's what you're up to.
Those emulators you can play on are bloated with ads or ad-free versions can be bought, but you never know what's modified in the system.
I use Nox to play some games, but i'd never input an important account in it. Other mentionable emulators are BlueStacks, MEmu or Andy.
Maybe i'm too wary, maybe it's for the better - some streamers though emulate their games in BlueStacks and pay tons of money in-app.

By my personal experiences, Nox has much better performance than, is much more stable than, and lacks the safety concerns of Andy and BlueStacks. It's a more capable emulator without the (auto-malware-installing) safety issues of the other two. I haven't used any but those three (though I can note that Memu, along with Andy and Bluestacks, did crash my system on Win10 even with HyperV uninstalled), but I get the impression Nox has an edge over Memu, Droid4x, and the others as well.

Nox is the best. The only problem is it still using Android 4

I used Nox, Bluestacks and Memu, out of the 3 I liked Memu the most.
But Nox and blueastacks are decents as well.

NOX and MEMU are good.

I'd say 2 options:

1. Use VMWare to create a virtual pc, then simply install android there. Works 100% and you'd be safe because it's contained there, in the virtual pc.
2. I've heard you can use an android sim in win10, tho I have no further info about it and what I did tried had bad results; it didn't work and think also messed up network configs..

I've used the virtual option and there're a few sandbox options for you, althought you might need something better than a toaster :P
I've tried Bluestacks and it sucked. Despite me having a decent pc, the soft crawled and left crap on my system.

1. Nox
2. Bluestacks
3. Andy

not using Emu anymore, most of them are heavy on my potato
I use Phoenix ATM

NOX

I'd only heard of BlueStacks (and never tried it), but it looks like the weight of opinion so far is favoring Nox or Memu.

bluestacks

I recommend Nox, used it to freq. get some Hearthstone promos via that emu, smooth, safe, but stopped playing HS year+ ago so didn't use it anymore, it was really good, and safe emu, just research little bit to see if nothing changed.

I tried BlueStacks but eventually got rid of it. Didn't like how it kept wanting me to do things I didn't want to do.

Bluestacks and Memu are the ones I've tried. Bluestacks used to download some apps automatically, but they've changed that in the new versions, so it's good now. I tried Droid before but I think that one's kinda sketchy.

Android Studio's own emulator is probably a "safe" one.
I have used Memu and Andy in the past and both were perfectly fine, not sure what they are like currently though.

Andy didn't work very stable for me, but MEmu works fine. No idea about others 🙂 both downloaded shit apps I don't need but I guess all apps work that way to get some $$$

No matter what, don't get Bluestacks. I've tried it, and it's a shell of its former self. Nox works great for everything I need it for.
