Black screen and green triangle cursor

I have Mac Mini Late 2012 with Yosemite 10.10.2

Two days ago I left my computer and display on and went out.

I don't remember if computer was in sleep or not at that time, but I pushed enter few times and it didn't wake up from black screen. Then I moved mouse and cursor was changed to green triangle having rounded corners.

I had to keep power on button down to restart it. It started ok and everything seemed to work.

But what that green cursor might be? I frightened that maybe there is some kind spyware and I started to change my passwords with iPad.

I scanned it with MacScan which found only trackware, and with Sophos antivirus which didn't found anything.

I didn't find anything like this with google.

Mac mini, OS X Yosemite (10.10.2)

I have the same legit problem. I can assure you its no malculous software,its some sort of bug in the update system i think. This could lead to a system boot loop failure tho, or highly likely its just a big annoying bug you have to deal with, you could try chabging ur display settings,or send back ur mac and ger a new one.

Do you also have Sophos or another antivirus application installed? If so, you should remove it correctly using the manufacturer's uninstaller and then see if your issues goes away.

Any 3rd party security software installed on a Mac offers no protection beyond that which is already built in. In addition, such software is the most frequent CAUSE of Mac system problems that are reported on these forums.

I have found the problem, but but diagnosis. The problem is triggered by going afk with a app on FULL SCREEN. This isnt anything bad, and wont mess up your mac. Its no virus either. Its just a bug that no one triggers due to this sanario. Just go afk with the app in window mode iinstead of fullscreen mode. I have tested this and its true.

Nothing bad indicated. If yu are still having problem uninstall Sophos using their uninstaller

Not infrequently anti-virus apps cause problems.

One day I was reading yahoo mail and maybe for 2 or 3 seconds appeared white pop up window, size about 4 inch by 4 inch. There read only "offline".

I Cleared HD and installed from old backup.

At sunday I was using computer with normal privileges, not main users. Also it didn't wanted to install anything, it didn't asked main users name and password. But maybe there's a way that spyware can be installed?
