Hello, yesterday at about 18:00 Mcaffe security (Preinstalled antivirus with Lenovo) rang me a notification and told me there was a treath. Confused i clicked on that and it showed me something called "UpgradeSys". Since i assumed this is a system file i thought it could have been a false positive, so i tried checking it with MalWareBytes, which also tells me it is a virus (Trojan). Giving up on thinking and wanting it gone, i try to remove it, yet Malwarebytes tells me to disable it so that it can be whitelisted and it is a system app, while Mcaffe cannot remove it even when it prompts me to and i confirm it. After doing a factory reset, the first thing i do is recheck if it is still there, and to my suprise, it still is. I have done a FULL factory reset which means all of my storage has been cleaned (Of my games , videos pictures etc) because the backup one didn't work either. I'd need some help with this.
