Halen is a benign non-memory resident parasitic polymorphic Win32 virus. When activated, the virus displays the following:
This is win32. Halen, a PE infector created by pxr[MIONS]
It searches for PE EXE and SCR files in Windows, the Windows system and current directories, then writes itself to the end of the file.
On Saturdays at 19:00 Greenwich Mean Time(GMT), the virus displays a message box:
Your system was fucked by win32. Halen. Written by pxr[MIONS]
It then slowly moves the screen image to the right.
