A couple times now, I have booted up my pc to see three command prompt windows open and then close immediately in windows 10. Should I be worried about malware? The windows open and close very abruptly so I can't see anything on them.
If I remember correctly when I had that same problem, but with only one command prompt opening, it had something to do with the avg antivirus loading something up upon startup.
On my Windows 7 OS, I went into the System Configuration window and disabled it.
That stopped the command prompt from showing up during the boot up but it didn't stop the antivirus program from running in the background. That still worked correctly.
