=====================


to get rid of Autorun.inf related viruses do the following in all of your removable and local drives.
if autorun.inf already exists then,
open cmd (command prompt) and change the directory to the root of (infected) drive,
i.e C:\ has autorun.inf
C:\>del /a:rhs c:\autorun.inf | md c:\autorun.inf
this will remove autorun.inf file and will create autorun.inf directory which will prohibit viruses from creating autorun.inf files in same drive.
repeat the process for all drives.
you can also create files named Recycle, Recycler, Restore, System etc in all drive to prohibit creation of folders having these names (thoese folders are created by viruses to complete their process in every drive)
and you can also create directories of same name that of virus file i.e fbak.exe, fix.exe, sscvihhost.exe, system.exe, etc
