Has anbody heard of a mal/ad/spy ware by the name of "rJ88Y58L.exe"?

I think it is the problem I'm running into with my computer. I will just be going about my business when all of a sudden out of nowhere talking, and media starts playing in the background somewhere on my computer. FREAKS ME OUT, because I cannot find the program is running, not even on my task manager. ANY insight or similar experiences are welcome. THANKS!
