A deadly computer virus called July Killer is expected to hit Korea this week after causing devastation in Taiwan, China and Japan. The impact of the virus is limited to double-byte versions of Word, which support Japanese Kanji and similar character sets such as Chinese and Korean, while bypassing English and European versions of Word.
The virus, which was first discovered in Taiwan on July 1, and believed to have been developed in China, can wipe out the full contents of a PC’s hard disk drive. It hit Japan on July 14. The virus enters a system through email or other internet data transmissions and lies dormant ahead of its activation in July. When activated it adds the command deltree/y c: to the auotexec.bat file and the next time the machine is started all files on the hard disk are deleted.
