Is my MacBook infected?

[zetbo]

Hi, I have downloaded OSX Sierra (10.12.6) yesterday from Hackintosh website, since I couldn't download it from the App Store. The file was 5.03GB. 

The installation went smoothly, installer and everything looked legit. When it finished I scanned the system with Malwarebytes. When scanning I noticed it's going through some weird items, and I don't know if they are on my computer or is Malwarebytes just looking for them on the system? It only goes through those files, nothing else (like documents etc.).

 

List of items:

Trojan.SteamStealer.CSGO

Adware.OperatorMac

Adware.Crossrider

Adware.Mindspark

Adware.The Player

Adware.Kilim

Adware.IronCore

Adware.SnapDo

Adware.Linkury

Adware.MixPlugin

Adware.Aqualious

Adware.OneSearch

Adware.VNPapps

Adware.ExtensionsSystems

Adware.Vidx/MacVX

Adware.MySearch

Adware.PremierOpinion

Adware.Conduit

Adware.FairyTale

PUP.logKext Keylogger

PUP.Jawego

PUP.Hotger

PUP.PCVARK

PUP.NikoffSecurity

PUP.WebWatcher

PUP.MacRemover

PUP.JDI

PUP.Aobo Keylogger

PUP.Award Keylogger

PUP.Optional.Crossrider

 

There were few other items, but it passed too fast for me to take the names. Also, I've performed full system scan using Avast, and BitDefender, but nothing came up. Should I wipe off everything of the disk, and get clean iOS, or is the one I'm using safe?

Thanks

It is NEVER a good idea to download macOS from anywhere other than the App Store. I would strongly recommend erasing the hard drive and starting fresh, with a new install. See the information here on reinstalling from Recovery:

Regarding the items you're seeing, those are things that Malwarebytes is looking for, not things it is finding. If it were to find something, it would let you know. But even so, I don't recommend using a system downloaded from a Hackintosh site.

Thank you for your reply. I was using Mountain Lion, and have problems verifying firmware on OSX High Sierra installation, that's why I'm trying to get Sierra. My friend uploaded a clean version of OSX Sierra from App Store onto his Google Drive. Gonna do a fresh installation of Mountain Lion, then going to download and install Sierra from my friend. 

Thanks for help

On a normal mac, with legally downloaded software, supposed to see it? On my mac, I saw all of these except for Trojan.SteamStealer.CSGO.

Yes, everybody should see a list of things Malwarebytes is looking for, during the scan. When the scan is finished, it will tell you if it found any so you can deal with them.
