Keep in mind some antivirus programs have given false positives before, since some trojans have been written that make a victim's computer mine without the owner's permission.  The result is safe miner software gets lumped together with the trojan as malicious software.

You can also scan a suspicious file with online services like http://virusscan.jotti.org/en which show you results from many antivirus engines.  This can help you conclude whether your own software is giving a false positive.

It is helpful if you provide the URL you used to download the wallet and the name of the archive file.

I have responded to your PM with a similar message.  Feel free to reply via continuing our PM conversation, or in this thread.
