Multiple Copies of explorer.exe

Hey ya'll. I'm running Windows 7 64 bit. When I got up this morning a program (WinMHR) that scans processes and files for malware, reported 4 copies of explorer.exe as infected. I always thought there should only be one copy of it. I also did a search for explorer.exe in Everything. Here's a screenshot: 1305909911-clip-117kb.png clip. I actually shows 20 copies of it. I was running an online backup with Digital Lifeboat that I was concerned about, so I rolled back with Rollback Rx hoping to remove these copies of explorer.exe, thinking Lifeboat had something to do with them being there. After rollback, they're still there and that's why I'm posting this.
Hope someone can help me clear this up.
Thanks,

My system reports "clean" and I have a dozen listed, most have the same entries as those in your screen shot.

What nasty is your malware scanner program reporting and where are they located?

Also, what version of Win7 are you running? I found this in the WinMHR FAQs -

Why do I get a warning on my 64-bit computer?

WinMHR is currently a 32-bit application. This means WinMHR can not scan running processes that are 64-bit.
You can still check any file using WinMHR, so a 'Quick Scan' or 'Full Scan' will check the files that launch the process that reside on disk.

Hey GEWB, I think my issue is different from the issue described in Wallonn7's link. I only have one instance running in task manager and it's location is C:\Windows. I'm running Win7 64 bit, but still using WinMHR because it still scans all programs for malware. It's the program that detected the nasties of 4 copies of explorer.exe as infected. Here's a screenshot: http://clip2net.com/clip/m80407/1305...-clip-84kb.png.
Wallonn7 if I'm wrong about your link, please let me know. I read it quickly as I have several things going on to try to track down what I need to do.
Thanks for ya'lls replies,
