There are multiple instances of explorer.exe running in task manager (currently 7), each one using between 10-40MB of memory.

Different explorer.exe processes are using cpu resources at different times.  I remember reading a while back that this could be a sign of a virus, but I've done a full scan with NIS 2010 and nothing showed up.  Can anyone give me pointers where to start investigating?

I did a clean install of Windows 7 last Friday -formatted HDD and all, so there hasn't been much time for anything bad to happen!

I found out what is causing the explorer.exe's to hang... If you give ANY arguments to explorer.exe in your shortcut/properties, to try to change the default directory from Libraries, it will hang.  For example, simply using "explorer.exe C:\" will cause explorer task to hang whent you close it... by hang, i mean the window closes, but the process remains in memory.  I had 15 explorer.exe's tonight....  There are tips on the net about how to get explorer to default to My Computer (which I was using this tip -- i HATE it defaulting to Libraries which i NEVER use)..... so edit your shortcut, and take off any arguments to explorer.exe.  See if this fixes it!

As expected , the tech support is clueless on this I see.

PS -- I just figured out how to default Explorer to My Computer... Its weird, but it works...  Rightclick drag your My Computer icon on the desktop over to a blank space.  Create a shortcut....  Now unpin any Windows Explorer you have from your Taskbar... Now, left-click drag your My Computer shortcut to the taskbar.    Now, if you just click this, you go to Libraries.... BUT -- if instead you right-click it, you will see the My Computer shortcut, and select this, and it goes to My Computer.... and there are never any EXTRA explorer.exe's hanging around!
