The virus infects Windows 95 and 98 files and will quickly infect your computer and can crash it. The virus has two methods, the first will overwrite or delete information on the hard drive by using direct disk-write calls, bypassing standard BIOS virus protection, while overwriting the MBR and boot sectors.
Some computers have a jumper on the motherboard, which acts as hardware write protection.
Some machines also have a DIP switch, which allows the flashing BIOS to be disabled. There are some newer computers that cannot be protected by the switch and therefore are vulnerable to the virus. If this virus executes it will leave the PC inoperable. Since this sounds dangerous you probably passed it on to many friends and acquaintances. Usually this type of warning is not real and is only used to tie up the internet and frighten people.
