False positive

I’m a Brazilian developer and I have a site where my clients make downloads of my programs.
I never had some problem in the past, but now the avast is blocking my programs and I dont can distribute and sell that.
My site is http://dropmaster.com.br/

The programs are there:

“Workshop” http://dropmaster.com.br/downloads.html

DropmasterMini" http://dropmaster.com.br/downloads.html

Dropmaster_3001+Multidrops http://dropmaster.com.br/areavip-installpacks.html

I wil be so happy if you can help me becouse I nedd sell my programs.

Thanks for help me:

False positive detection caused by heap corruption caused by std::string destructor generically flagged as HEUR.Trojan.Win32.KillFiles,
as genuine malicious variants of the PE EXE file written in Borland Delphi would delete autoexec, bat.

Report this to virus AT avast dot com as a “BobSoft Mini Delphi” generic FP, as history is repeating itself here, see: http://forum.avast.com/index.php?topic=79703.5;
