Random command prompt appears when i closed an app

[Ravachol]

Hello, a couple hours ago i installed some video converters, i don't know if they are safe, but i scanned with malwarebytes, it found nothing.

Now when i closed any app (firefox, photoshop, adobe acrobat vs.) random empty command prompt appears and closes itself in a moment. What do you think is the problem?

Note: I checked other threads, i don't have office installed in my pc.

i wouldn't expect it to be Office, that was a few months ago...

Tried any other AV programs? If not, try https://www.bitdefender.com.au/solutions/free.html and see if it agrees with MB

I don't know if this fix will help: http://www.tomsguide.com/answers/id-3234485/command-prompt-popping.html

I think bitdefender solved my issue, i also used neshta.a removal tool.
