Program sometimes flagged as virus

W开发者_StackOverflow社区hy is it that sometimes my program is flagged as a virus for some anti-virus software, when it's not?

Are you talking about false positives?

May be your program contains some code snippets which are considered as VIRUS code by anti-virus programs.

Antivirus protection systems often use heuristic algorithms that may give false postivies sometimes. Maybe your program has a certain set of suspicious function calls, specific low-level instructions or whatnot. Networking is likely to cause an antivirus alarm as well :)
