RE: False alarm [KLAN-40418281]
Hello,
Redemdl.dll - Virus.Win32.Induc.a
This is not false alarm.
This is a new type of virus. It can infect Delphi source files, so when you compile your program, it will contain virus code. If you are a programmer, please check your source files (including standard Delphi .pas files) for the following virus code:

dll确实有点小问题 0x5bd4居然有代码……搞不好我delphi被感染了
