Buzzen does not contain malware. This issue is due to Buzzen testing a new advertiser with more lax image policies than Google allows. I do not know why this issue all of a sudden happened as the advertising code has been part of the Channel List page for a few months now. We are in contact with Google Safe Browsing to sort this issue.
In the meantime you have four options you can do until Google removes the flag from the page.
1) Click on the details button, then click Visit this unsafe site. Again the site contains no malware.
2) Turn off safe browsing in chromes options - Settings -> Advanced and Toggle Safe Browsing to off
3) Use the alternate channel list at
http://chat.buzzen.com/ChannelsList 4) Use Edge or Internet Explorer as they do not use the google safe browsing database, but Microsofts.
Again there is no malware on Buzzen.
