microsoftonline.com Blocked


Recommended Posts

Today a blue colored window, not in a browser, appeared for a major Windows 10 update. i looked legit so I ran it. After it finished several minutes later, Edge was on screen with info on the update. Then MalwareBytes blocked microsoftonline.com several times. Below is an example report. From a few searches, it seems to be legit. Why does Malwarebytes block it?

Thanks for you help..

I'm also experiencing MB blocking login.microsoftonline.com as a malicious website.  I'm running version 3.3.1.2183, component package 1.0.262, update package 1.0.3458 on Win 10 Home (Fall Creators Update, latest patches).

For me, the blocking just appeared this afternoon ... not after a Windows Update or upgrade.

I have a similar issue.  Microsoft forced me to do an update yesterday.  Since then, a Malware Bytes alert has been popped up incessantly saying that login.microsoftonline.com is malicious. It references C:\WIndows\System32\backgroundTaskHost.exe

This annoying and disruptive alert pops up every 10 seconds and disappears a couple of seconds later and not sure what to do with it.

I am running windows 10 Home.

I have a similar problem when I try to log into outlook.office365.com.

When the url is triggered, it's redirected to login.microsoftonline.com and login.microsoftonline.com is blocked by Malwarebytes.

If I add login.microsoftonline.com to exclusions, my chrome browser says the connection is not private NET::ERR_CERT_AUTHORITY_INVALID

When I try to go from another computer that dosen't have Malwarebytes, I don't have that problem.

I'm using version 3.2.2.2018

Component package version: 1.0.3459

Update package version: 1.0.3459

MB is blocking all outbound connections to login.microsoftonline.com. This just started a few hours ago. Last Windows 10 update installed on 12/1/17. Is there a problem @ Microsoft or is this a false positive?

I want to whitelist it, however, if there is an actual problem I will wait until it is fixed at Microsoft.

UPDATE TO POST:

I did whitelist login.microsoftonline.com. Tried Chrome, Opera and Firefox and all show a secure connection with certificate expiration 5/7/18.

Every one please update the database.
