Hey, can someone help me with this? My computer always has this pop up that says

Error: runtime error 5 at 0099729C

What is this? sometimes if I close it, two pops up, and when I go into task manager it doesn't exist as it's own program, but my system idle is using 99 percent of my computer when this is on. I went into control panel and went into Admin tools : services : and disabled some stuff (to be able to stop it from duping itself), did I mention my firewall might be corrupted? Can anyone plz gimme some answers?
