Explorer.exe demystified

Have u ever wondered what is "explorer.exe"  many of us may question ourselves does this process make us to explore the system like chrisopher columbus did ???may b many of us knew about this process earlier iam making this post for noobs.This process is developed by Microsoft ,it acts as a graphical shell between the user and the system.The taskbar,the widget bar all these are because of this shell.exe file.Let me tell prove it whenever ur desktop freezes launch task manager kill the process explorer.exe and click on new button type explorer.exe click ok to revive the process this should solve your problem.This process is safe as long as it resides in c:\windows either for windows xp or later versions.If you find this process anywhere else then am sure it's a infected file never dare to touch it. Get any latest antivirus tool from eset or kaspersky and run it.
