W32/Yaha-R is a worm from the Yaha family.
W32/Yaha-R shares many of the characteristics of W32/Yaha-Q.
However, W32/Yaha-R stores itself on your hard disk under different file names to those used by the -Q variant. W32/Yaha-R places the files wintask32.exe and exeloader.exe into your system folder. (The -Q variant uses the names mstask32.exe and exeloader.exe.)
