@ @ will this utility be able to run from the command line silently with no user input from the SYSTEM user context? That is what MSPs will require so we can easily script it in our RMM systems like Kaseya and Labtech.

@ I was doing some beta testing last night and yes, you can run from CMD. It is an executable that does run silently by default so you can push it out via your RMM tool.

Some of the ability is already there like requesting a checkin with the console. They just need to expand on it and maybe add a CMD interface.
I agree.  If Webroot had a documented commandline set of switches and options, it would make life much easier for MSPs; we could issue scripted commands immediately to machines.
We are SysAdmins. We walk in the wiring closets no others will enter. We stand on the bridge, and no malware may pass. We engage in tech support, we do not retreat. We live for the LAN. We die for the LAN.

Hi When you get the tool from support, plan to push it out to your endpoints and it will execute automatically. It will restore files from this incident to their original locations. So you should plan to use a script or your RMM tool to push it to endpoints.

This is not a fix, we can only hope that it didn't do too much damage.

What do you do if you manually added an override for specific policies?  How do you undo that?

@ Would it be ok if we run it on all machines though? We aren't certain which are afffected or not so it would be a hassle to sort through thousands to figure out which are affected if we could just run it everywhere without any issues.

Is there a full explaination as to what this "Fix" does?

It moves the quarantined files back into their proper folders, what about systems which we've manually restored quarantined files already but the agent is unresponsive to the cloud?

What else does this fix do?

I hear you. There is not a problem deploying across both affected and unaffected machines.

Yes you can deploy the tool using the Download and Run a File agent command from the WSA console or by using any other deployment method that you may use.

Please post an actual fix. This is useless as the scans don't show the MD5 of the quarantined files.

Hi No, we dont want to hang on the phone with your team while you use it. They want to understand (quickly) if the person requesitng the tool is confident in his abiltiy to just run with it. You know some people ask for tools like this who dont actually know what theyre doing. So you will be given access to download it very quickly once you connect with support.

I am not getting console commands to run at this time still... hoping that gets resolved as well>??

The rule that caused this issue was live for 13 minutes before it was caught by our in-built safeguards. The result has been to mark files as trojans false positives. The rule was removed and we are in the process of rolling back all of the false positives that reside in the Webroot Threat Intelligence platform. Once this is achieved, the agent should pick up the re-determinations. Because the rule has stopped, no other endpoints should be affected by this issue. 
 
As you can imagine, we are all working hard at finding the best resolution for this issue.

UPDATE 4/27/17 9:21 a.m. MNT: We have 0 calls in queue on our phone line, and are working through about 100 tickets related to the False Positive repair utility. A good portion of those are simply awaiting customer verification.
 
If you haven’t yet submitted a support ticket and you need the repair utility, please do so here. Include your phone number as well with the support ticket.
 
Our sincerest thanks to the MSP beta customers who worked with us to further test and validate this repair. We truly appreciate the support of our customers and thank you for your patience.
