Virustotal reports infected

Just downloaded and ran the installer through virustotal. Antiy-AVL detected Trojan[Packed]/Win32.Morphine. Here are the basic properties:

My best guess is that this is a false positive or the installer is getting modified after the download.

I just did a quick scan using virustotal's URL based online scanner and it comes up clean. You might try first using the URL based scanner here:
https://www.virustotal.com/gui/home/url

and put in the URL for the program installer: https://www.flexibleretirementplanner.c ... -setup.exe

Assuming that's clean, the next step would be to upload the installer you're trying to run to see if the online tool detects anything in that.

I also see the URL based report is clean. What I did before my first post was actually your second suggestion. I repeated the download and then upload to virustotal.com on two additional computers, one of which I never log into. The same engine found the same trojan on all three systems. Unfortunately the URL based scan does not include the details found on the upload scan so it's hard to tell if virus total is seeing the same file.

It would really be helpful if someone else could repeat the upload so I can rule out a trojan that has spread across my home network.

When I upload a copy of the downloaded .exe to virustotal's online file scanner (not the URL scanner), I also get 1 out of 56 engines reporting a positive.

VirusTotal reports that the positive is from Antiy-AVL. I've emailed Antiy-AVL suggesting this is likely a false positive and am waiting for a response.

I double checked on my web host to make sure the file date is the same and I also rechecked that the file's security certificate still has a valid signature from Random Walk Ventures.

My best guess is still that this is a false positive, but you'll have to make your own decision about how to proceed. The file was uploaded to the web server in february. doesn't appear to have been modified since then and no other anti-virus engines are reporting any problems with it.

I'll post back here if I get a response from the folks at Antiy-AVL.
