Recently, a folder appeared on my hard drive, without me having done anything to make it appear. Its name is a random string of letters and numbers that I shall not bother to memorize, but it contains a single file, called MPSigStub.exe. As far as I can tell, that file has no purpose, but I cannot delete it, even when I use a file shredding program, which greatly bothers me. The file itself is not harming my computer, but it still is annoying, and I do not wish to keep a file that serves no purpose, so is there any way to delete it from my computer? What advice can anyone here offer? Thank you very much.
