Hi everyone,
My laptop has been giving me an error lately and it's annoying since I don't know how to remove it and it keeps popping up even when I close it. Here's what the error looks like:

I got home from work one day and my nephew was using my laptop. Next time when I used it, however this error kept popping up. I talked to him and he actually downloaded a downloader for a PS1 ISO. It turns out it's the root of the problem, but even after removing the installer I keep getting the error. Can any of you guys help me out? It would be much appreciated!
