Wanhope is a harmless non-resident parasitic Win32 virus that recursively searches for Win32 PE EXE files in the Windows directory, the Windows System directory and the upper level directories.
While infecting the virus writes itself to the end of the file.
The virus does not manifest itself in any way.
Wanhope has a bug and can corrupt files while infecting them. Corrupted files will perform illegal operations while starting.
