That’s a false positive, or as I’d like to call it irresponsible defamatory, slanderous, libellous and malicious. Get a refund for your “anti-virus”. The makers of anti-virus software will flag anything, from anyone, for any reason and will never ever take responsibility for their actions.
All of the above is dependent of course on that you have downloaded the correct software from our site, and that it’s digitally signed by us, “AxCrypt AB”, and not just any file named AxCrypt-1.7.3180.0-Setup.exe, but the link does appear almost ok although it can’t actually be used directly as a link. You will be redirected to the new download site. If you go to http://www.axantum.com/AxCrypt/Downloads.html and download it, you’ll get the correct file.
