StartUp.xls宏病毒清除方法:
第壹步：清除C:\Documents and Settings\administrator\Application Data\Microsoft\Excel\XLSTART下的StartUp.xls；
第二步：清除C:\Documents and Settings\administrator\Application Data\Microsoft\Excel\的Excel11.exe(約236K)，Excel程序會自建該文件。
第三步：新建\Documents and Settings\administrator\Application Data\Microsoft\Excel\XLSTART\startup.xls文件，輸入以下代碼就行了，以後再打開帶毒的excel文件就會自動清除excel文件自帶的病毒宏代碼了
