Rewrite your code so popular anti-virus programs don't flag your dll files as malware. I am not going to notify Avira of a possible false positive for shareware, that is the developer's job.

updatemgr.dll is flagged by Avira and quarantined so I am not able to use today's GOTD and I don't care if it is most likely a false positive, as it is not my job to ensure that the file is safe or report it to Avira. That is something I may want to do for free or open source programs, but for paid shareware, it is unacceptable.
