The website lemmonet.azurewebsites.net appears to be linked to malicious content. The domain azurewebsites.net is genuine and linked to Microsoft Azure web services. Looks like this is either a user who has set up this site for malicious content, an AD network that is serving malicious content or maybe the site has been hacked.
There is also quite a few social media profiles that contain links to this domain, again very suspicious accounts used.
Also see the following which shows a suspect URL path on this domain (there is many when you look them up) :-
This appears to be linked to another URL, again appears suspicious.
Did a bit of research and found a website which appears to be an Ad company called LemmonNet, so I tried their own website and my browser crashed, and CPU went to 100%, very strange, lucky this test was from a test machine ! Very Strange !
