Having decided to learn about sandboxes and download Cuckoo, Avira tells me that this is a malware site that can infect my computer:
https://cuckoosandbox.org/ -> click "Download Cockoo!" -> Avira warning, blocking the download website
I am little bit astonished since Cuckoo seemed to have a good reputation and is even mentioned positively in AVIRA blogs (https://blog.avira.com/cuckoo-sandbox-vs-reality-2/ and https://blog.avira.com/vmcloak-create-virtual-machine-easy-way/, so I think this might(?) be a false alarm.
Questions: Are there any known security issues with Cuckoo and the Cuckoo website itself? I Would be surprised, but are there download sites safer than the genuine (please correct me if this is a fake site) https://cuckoosandbox.org/?
System information: Win-10, Firefox 52.0.2, Avira free, version 126.96.36.199 (in AVIRA help, there is usualle just the answer that trusted websites can be unblocked, but my question is how to tell if trustworthy in this special case)
