Slack page is identified with malware

sidball · 2015-10-28T09:02:36.000Z

Today I updated my avast’s virus definition, then 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?

I can’t access slack chat page from browser because of this. It keeps showing loading screen. Of course if I turn off avast shield, I can access the slack page again.

Avast spec:
Virus Def version: 151027-1
Program version: 10.4.2233
OS: windows 7 SP1 64 bit

Next time, use Viruses and worms forum section for reporting virus and false positive problems

seems there is a redirect link in a compressed java script…

will try to get some attention to your post from avast team it may take some time before you see any reply

I, too, am experiencing this issue. I use Slack via FireFox browser, not the locally installed version.

Region: New England.
System: Win7 Pro, i7 Proc, 8GB RAM, 512GB HD, 50% HD free, MSO2K10, FF41.0.2.

Me too! Slack via Firefox

To immediately solve the issue, please add URL https://slack.global.ssl.fastly.net/773e/js/rollup-core_required_libs.js to WebShield exclusions in Avast settings (Settings > Active Protection > Web Shield (Customize) > Exclusions > URLs to exclude list).

In a hour or so, the issue will be resolved via the next virus definition update as Sirmer wrote above.

Thanks.

As Petr said, latest definitions, Slack & Avast friends again!
