I use Firefox with auto update. This very morning I can’t download any file from the site, since Firefox says “Blocked: may contain virus or spyware”.
Same thing with Chrome.
FF and Ch will not download .v4p and .zip (try here: https://discourse.vvvv.org/t/12693 and here: https://discourse.vvvv.org/t/12691
Made a few searches and discovered that FF uses Google Safe Browsing (http://www.ghacks.net/2014/11/19/bypass-firefoxs-blocked-may-contain-a-virus-or-spyware-message/).
Here they say that
Firefox handles the checks different than Chrome. Instead of communicating directly with a Google server whenever a user of the browser attempts to access pages or download files, it is checking a local copy of the blocklist first and will contact the server only if a match is found.
which somehow has changed, for vvvv is not in my blacklist (double checked, win internet options included).
Finally I visited this page
where G says that something happened on vvvv.org.
Webmaster is probably already aware, but you know…
