It will then infect other files when they are copied or opened. Infected files will be the same size as the original file because of the unique infection techniques used, so this make the virus difficult to detect. The virus will first look for empty spaces in the file, then it will break itself up into small fragments and hide in the file. However the virus has some bugs, and in some cases can crash your computer, when infected applications are run. The virus has two payloads, the first will overwrite or delete information on the hard drive by using direct disk-writes 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 payload executes it will leave the PC inoperable unless the BIOS is restored or replaced. Scan your systems with the latest version of VirusScan 3, or 4, in addition, Dr Solomon's Anti-Virus Toolkit and FindVirus users are protected from this virus as all these products have detection and cleaning. Do not start your system on the 26 th if you are concerned you may have received the virus and have not scanned your system.
