More likely, it is simply your use of the Delphi RTL in general. There are plenty of malicious virus/malware in the wild that are written in Delphi, and so it is not uncommon for ordinary Delphi programs to sometimes get flagged as false positives because they share common RTL code.

You can't, because you don't know what definitions are being used to trigger the alert in the first place. All you can do is submit your app to the anti-virus/malware companies for review and hope they stop flagging it.

There are plenty of decompiler tools available (IDA, etc), but you can't recover source code from decompiling, and that won't help you in this situation anyway.
Your best bet is to get yourself a code signing certificate. There are cheap options available.
