detect unsafe hidden file easily

In here I will discuss about removing virus and worm files from computer. Virus and worm are often seen disguised  as system files. For this we can not detect them doing 'show hidden files,folders and drives' in folder options. To detect them we need to go to the Folder options in tools menu. Then click view and 'Show hidden files,folders and drives'. Then unmark the followings -'Hide extensions for known file types' and  Hide protected operating system files (Recommended)'. Click Yes in warning message. Then all your virus and worm files including your original system files will be displayed. Identify virus and worm files and delete it. Just don't delete your system files and be careful about clicking virus and worm files.
