Outlook Autodiscover triggering: HTML: RedirBA-inf [Trj] and URL:Mal

Hi all,

Apologies if this is something hat has already been reported; but it appears my outlook auto discovery server is continually generating an ‘infection’. Currently Avast believes I have 11,568 infected files…

It seems the contents of the outlook app has the problem as well as the .tmp file.

I was running Microsoft 2011 for mac, deleted this and moved to O365 hoping to fix the issue, but it seems to have continued.

Need to know if anyone else is experiencing this or if it is indeed a genuine infection. If genuine, advice on how to resolve (N.B. i’m not the Office admin - merely a user).

currently on Mac OSx Yosemite 10.10.5

Avast Free version: 11.5 (45630)
Virus Def Version: 16021501

hope you can help, let me know if you need anything more.
