Reset System and Hidden Attributes for Files or Folders Caused by Virus

This is simple method of doing it without using any software. Just run command prompt (Start -> Run -> CMD for XP, or for Vista and 7 Start -> type CMD in search box, right click and run as Admin), type the following command:
attrib -H -S C:\path\to\your\file.doc /S /D
You can also use the asterisk character to define multiple extensions. For example:
attrib -H -S C:\raymond\*.* /S /D
This would remove the Hidden and System attribute of all files in the raymond folder on the C drive. The /S and /D arguments are optional. /S will recurse down into all sub folders and /D will unhide the folders themselves if they have the System or Hidden attribute set.
Just to point out, it’s probably not the best idea to use something like “C:\*.*” as this will unhide the whole drive including files which Windows has set as hidden or system by design.
