If I install a peice of PUA that is undetected by WSA and set to monitor, couldn't I therorectically choose 'block' to revert the changes of this PUA? If so, this would seem to be a much easier and more thorough way of uninstalling unwanted software (if done right of course).
That was just an example above for future reference.

Thanks!
Only the changes made by the monitored process will be journalled, so only those changes would be rolled back.
Using what you saw with Focus Writer as an example, journalling and rollback worked as would be expected. The Monitored file was the Focus Writer application file, which created the document, so the change of the created document was rolled back. Since that process did not create the installation files, those files would not be deleted.
If you wanted to remove the installation files, you would need to go to Manual Threat Removal, and select the installation file for Focus Writer. If the installer was monitored and journalled, the changes made by the installer would rolled back.

Hi mar122999
I understand what you are asking which is essentailly what I paraphrased in my last post above. I still believe that a manually initiated change from 'Monitor' to 'Block' will not initiate the rollback function even if the 'Monitor' was set automatically.

Well, I was refering to the fact that if WSA marks a PUA on install as 'monitor' (user not doing it). Or any file really...I would like to have the ability to utilize the rollback feature to the best of my ability if of course I know what I am doing.
If a piece of malware, pua, ...whatever installs and I know for a fact that this file is bad...I check the System Control menu and see that it was classifeded as 'monitored' by WSA. Instead of scanning with Malwarebytes, calling WSA support, etc. I could therorectically just block the file, and rollback any actions it may have performed (which would be hard to determine if it did any at all...better safe than sorry), and then scan with a third party program to make sure the remnants are clear. This method doesn't seem detrimental as long as you are blocking the right programs.

Good question Daniel!
Again, I know some of the material we are discussing here is beyond the average user, but we do get questions on it and it would REALLY help the more advanced users here to be able to really fully understand it for our own use, but also in trying to answer questions on the Forum. We can answer much more accurately if we understand more fully.
Thanks you Dan for all the info so far!

Yeppers I agree in the case of the OP it would not rollback because it's after the fact! @ can we get some info on the SafeStart Sandbox could a user run a program inside the sandbox to test programs and use it to remove all traces of the program like in the case of testing a program to see if you want to keep it or not? http://www.webroot.com/En_US/SecureAnywhere/PC/WSA_PC_Help.htm#C10_SystemControl/CH10c_UsingSafeStart.htm

Hi Daniel...I am with you on that. I do the same...;)
But more specifically if I, a user mark a file as 'Monitor', it journals, etc., and then I switch it to 'Block' (the OP asked..."couldn't I therorectically choose 'block' to revert the changes"...I believe that no rollback will or can occur. That is what I would like to confirm, and also...if I have manually generated journals, as per the above method...if they remain on disk...in the apropriate directory, then could Support use them as part of a manually initiated rollback action...if such a thing is even possible?
C'est tout, mon ami...:D

Yes and I Agreed I don't even play with it, but only to set to Allow from Monitored when I know it's a safe Program and processes from an updated program and most times I contact support to get them Whitelisted and of courses if it's not good there are not going to Whitelist it they will mark it Bad and WSA will remove it.

Hi Daniel, thanks...but this I know other than the last part and I am sure that I have seen a thread in which it was stated that WSA setting something to Monitor and a user doing that does not have the same end result in terms of the rollback...hence why Webroot do not recommend (at least as I understand it, but perhaps incorrectly) that users set files to Monitor.
@ Roy...I think that it was in one of your post in a thread a good few months ago where I thought this was said...can you by any chance recall this and advise as to whether what I am saying is a delusion or not?
Many thanks

"No you can add process to the Identity Shield if you so wish. I dont have the list of native apps that automatically handy at the moment. Any executed process that is unknown in our database will be journalled. If its determined that its bad its changes will be rolled back. This as I said earlier is only one component of our program.
For instance on my PC here, a new version of this application was released recently and its a new .EXE
Monitoring process E:gamesSteamsteamappscommonWar Thunderaces.exe [B2771208D7A3ABD19ADF7F1A7E797AB7]
The client is keeping an eye on what its doing. If it starts doing things that the client determines is bad (behaviour based) it can locally block it too in which case you may see:

See the different levels and even Roy showed Level 11 so it would depend on like they said already the Behaviour is taken into account from the Cloud. I don't think they are willing to explain the many levels in public as we don't want to give the malware writers any inside info!
I hope you can understand what I'm trying to say without saying more?

From what DanP said here, it looks like if the user manually changes it from Monitor to Block, on that particular PC, and only that PC, WSA will now recognize the file as "bad", remove the file, and trigger the rollback for any changes made while the file was in Monitor status.
This would trigger a "bad" determination, and rollback, only on the specific machine that has had the file manually marked as "Block".

Would it be possible for Dan or Roy to advise/clarify for us as to what happens if a user has manually sets a file to 'Monitor', and so limitation of activity/journalling commences...OK...but what happens if the user decides that the file is 'bad' and so sets it subsequently to 'Block'? It is my understanding that, unlike when WSA determines a file should be blocks, does so and the rollback takes place, that in the case of the user 'determination' of maliciousness the rollback process does not start! Is that correct?
And if it is then could the user contact Support and they use the journalled information (held in the dbxxxx.dat files) to initiate a rollback. As if neither of the above occur then there is a question as to what use there is to manually setting a file to 'Monitor'...yes, that will limit activity but in the end that is all if the journalled information cannot be used, etc.
Many thanks in anticipation.

I was in grave error above on my first reply then... I did not think the rollback would be automatically triggered. Thank you VERY much for the clarifications
I know very well to NOT advise a general user to blindly go about blocking files... it is very dangerous if they happen to tag a Windows file... but at the same time I think it important that the more advanced users and members here have a GOOD understanding of it. I did not.....
I am not sure if I have a good understanding now, but at least it is a lot better than where I was yesterday at this time 🙂

Oh I fully agree with that.... .Untold damage can, and does, happen.
What I was curious about was simply for the information of advanced users, if the rollback function would be automatically triggered to undo any changes made whlie the file was in the Monitor status once the file was placed into Block status.
I too have seen WAY too many times when people start removing things that they don't know what it is, or what it does. The number one rule is "If you do not know what it is or what it does, DO NOT TOUCH IT.

Manually setting a file to Monitor would cause the file to be monitored and journaled from the point that the file was set to monitor. Only changes made by that file after it was set to monitor would be journaled and be able to be rolled back.
Monitoring will limit program access. There are several different levels of monitoring that are based on the behavior of the file, so in the case of a file manually set to monitor this would be limited to the behavior of the file after being set to monitor.

I just did a short test with a peice of odd software that I have in my collection (DVR program). WSA marked it for monitor. I then chose "block", scan/delete the file...but no rollback of the installation. I am guessing that Webroot will not rollback the program/folders/files/registry ...etc, but only the files created/changed AFTER installation of the program. I'm confused now lol.
UPDATE: I did another short test using a program called Focus Writer:
http://gottcode.org/focuswriter/
WSA marked as monitor, I open the program...create a doc and saved to desktop, blocked progam...scan/delete and during cleanup phase the file that I created dissapeared. So WSA doesn't delete the installed files of the program, only what it CREATES after installation. I guess ;P
So if you come across a computer with PUA/riskware/scareware ...etc., I'm glad that I can block, scan/delete, then uninstall the program to know that any changes done to the system (wallpaper change, homepage change, default search changed ...etc) would be rolled back (if the changes were done after installation...i'm not sure if changes during installation are rolled back). I guess a dev would have to answer when the journaling process starts.
