please forgive me cause im new to computers if this is a crazy question. in task mang. under processes it has iexplore .exe listed 2 times. and it has explorer.exe once. is this normal and nothing to worry about? i have read explorer.exe could be malware. when computer starts and icons on desktop come on they go blank then come back on. and sometime webpages load real slow or not at all. i have ie8. and vista. thanks in advance.
Sometimes malware can come with file names that are the same as actual Windows programs.
explorer.exe is the program that makes your desktop and start menu available. If you kill that, you'll just have a desktop and whatever programs you happen to run. iexplore.exe is the Internet Explorer browser. Hope this bit helps, sorry I can't answer the others.
You should have only one instance of explorer running but since you are using IE8 you could have multiple instances of iexplorer in task manager. From what I understand, when using IE8, there can be additional instances of iexplorer showing for each tab open.
explorer.exe should appear at least once as it provides the desktop, start menu, task bar, etc. Opening My Computer or another folder may spawn a new explorer.exe process or not (depending on your configuration.) Internet Explorer 8 implements a multi-process architecture wherein each tab and window operates in its own process as a child process of a master iexplorer.exe process. So it's quite expected that you should have more than one iexplorer.exe
