Doug,
I sent you an email about this issue but wanted to flag it on GH as an issue as well:
Doug,
I have a client that utilizes ConvertAll in his daily workflow, and has encountered difficulties recently due to Webroot Secure Anywhere antivirus software quarantining the C:\Program Files\ConvertAll\CONVERTALL.exe due to a detected Trojan.

I've run both the all users and single user installers through https://www.virustotal.com/ and it appears the all users installer does indeed contain a trojan. The single user installer does not.

Just wanted to send over a heads up as your web host file repository may have been compromised.
