Using WinXP PS3 with Avast, Online Armor, MBAM, and Trojanhunter. I have the latest stable version of Chrome. I can't find this "problem" mentioned anywhere in the FAQ etc ... when I launch Chrome, I have two or three (!) copies of chrome.exe listed in Windows task manager. When I first noticed the problem, it was three; when I tried just now, to see if it was reproducible, it was two. Whenever I've checked, since I noticed this weirdness few days ago, Firefox (my preferred browser) has only ever had one copy, as I would expect. But that's the only one that behaves as I expect, since I started checking. Tonight, IE had two copies of itself, and so did Safari (that I just installed tonight).
I say it's a problem because it seems pretty suspect to me. The actual browsers all seem to work fine. But what are the "shadow" copies doing? Should I suspect malware? Nothing shows up in my security software.
