Windows 7 x64 multiple explorer.exe*32's present in task mgr
I switched to WIN 7 Pro 64 bit more than a year ago. a clean install of a legit copy. When I open windows, I open cmd.exe and task mgr before anything else, and by habit peruse task mgr processes list at start up and periodically.
Recently, I've noticed, besides exlorer.exe, 2 to 5(or more?) additional instances of explorer.exe*32.
with no apps open besides command prompt, chrome browser. no windows folders open
sometimes I can end task a few of them, but not all; once this lead to a windows shutdow, when I persistently tried to close them all;
they are sucking system resources to varying degrees. I have done virus(aVast) and Spybot S&D scans, which found no alarms. Any tips or explanations appreciated.
TIA.
