That's odd, because I've used the site, running AVG, Avast, and Windows Defender on separate occasions without a problem.
www.virustotal.com/url-scan/report.html?id=6de7a7e12a88177f62f890f8e4449ed5-1304549073 identifies the other website as clean. And since I know that you vowed not to click on any more links provided, so if you don't trust that link, you can just google "VirusTotal" and put the virusscan.jotti.org website through VirusTotal's scan. It will come back clean. In fact, you can just use VirusTotal's scan on any of our trainers if you still don't trust the jotti site.
