(The following was because the person I wrote this to initially used the WindowsRAR package to create a self extracting executable file - I frown on that intensely except for something that you give only to somebody else you know personally.) Okay, your wham doozle executable has been identified as bad by one or more AV vendors. Now, what can you do if what you have is valid? 1. If you aren't concerned about Copyright and don't want to maintain your control over said code then GPL the code. If you want to retain the Copyright, take the code down to a Notary Public in the United States or something similar in other countries and have it notarized. That preserves your priority. A bound notebook with hand written entries seals the Copyright to you. If you have the notebook , show that to the Notary Public. 2. Send what you have to the companies that have marked what you have created as bad. Here is another an excellent one since they will share what they have with other AV companies: http://cgi.clamav.net/sendvirus.cgi Give them the source code and the entire procedure you used to create the file. That includes the use of self extracting exe file creators like Windows RAR, Zip, or what ever it was that you used to create the file. But be sure you include the source unless it is too big. In that case, ask them if they want it. Then wait for them to clear it. If you have nothing to hide they will do it. Here is another partial list of AV companies where you can submit what you have to them: http://portableapps.com/node/21968 Do not blame me or even them if it is not complete. Many AV companies have NO way to contact them. But since ClamAV will share with everybody that is a good place to start. A rule of thumb is in order here though - no source code for a program coming out of the blue means I DO NOT WANT IT! Even if ALL the AV companies mark it clean I STILL DO NOT WANT IT! 3. When you repackage it again, use something like Inno setup or something similar that allows you to enter your Copyright. That still makes it incompatible with me since I need everything I have covered under one or another GPL license. But if you aren't going to put Copyright into your code - I DO NOT WANT IT! I am sorry, but on this one that is ABSOLUTE! IMHO, only an idiot would accept code with no copyright in it from somebody they don't know.
