slack team page from firefox was blocked with avast

When I opened a slack team page from firefox and I got this malware warning:

https://slack.global.ssl.fastly.net/64b5/js/rollup-core_required_libs.js|{gzip}
JS:Redirector-RS [Trj]
C:\Program Files (x86)\Mozilla Firefox\firefox.exe

Is it possible this is false alarm?

Attach your basic diagnostic logs. (MBAM, FRST and aswMBR)

Pls break the HTTP link to Hxxp.And this is a original Malware site as Fortinet:Malware site.

Thank’s for your help but it seems that’s a bug
