Every time I leave Internet Explorer open for a few hours, I come back to an extremely sluggish PC and about a million iexplore.exe processes running.Occasionally I'll open IE9 to test a website. Sometimes even after I close the browser (but forget to kill the process), it will start spawning its own additional processes, but not browser windows. And no, it's not malware or spyware, thank you very much. Anybody know what's up with this? It's getting super annoying, and I know I can't be the only one with this problem. I'm running IE9, but this happened with IE8, as well.
