This is a Windows 95 virus, infecting EXE program files and SCR screen saver files. Win95/Savior does not go resident; every time it is executed it infects EXE and SCR in the current directory as well as in the \WINDOWS and \WINDOWS\SYSTEM directories.
Win95/Savior activates on the 7th of January. At this date it displays a dialog with this text:
HUM4N G0D THA7 WAS MAN-M4DE WH3RE 1S Y0UR SAViOR N0W
After this it overwrites files in several directories, crashing the system and making Windows unable to boot. You need to reinstall Windows to fix the system.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
