    Hi EveryOne

    I am very interested in this thread particularly with Ransomeware on the rise and also the free Secure Folders.

    I would be most grateful for help on what folders need protecting and whether they should be, hidden, read only, Locked , No Execution. I have Windows 7 Three browsers IE11, Chrome and Firefox + Thunderbird.

    Similarly, which .exe files should be protected and what type of protection.

    Can you just protect all of a particular drive, say C:?

    Thanks for your help

    Terry

    @TerryWood
    Personal private data is the key. For instance is advisable to lock Documents folder or any folders where you currently save important personal files such as photos, books, word, excel, etc. Even folders in external drives or partitions.

    It depends on what you want to protect and how.

    For example, photos, videos and music, you want those protected as read only. This way you protect files from ransomware modifying them, but you can still view them by ANY even non-trusted app. Making it safe but comfortable to use.

    Locked should be used for example to protect browser user profile folder where bookmarks and locally stored webpage passwords are stored. Give only browser the right to access it and you can reinforce the security quite a bit that way. There will also soon be "Hidden and Locked" option which would even further enhance this by locking access and even hiding files, sort of almost double secure.

    Hiding works similar to locked, if app can't find the file it can't access it. Similar to Locked, just that the files are hidden, but if you can dig them up, they can still be accessed. Which is the case in certain situations.

    No Execution, to my knowledge means you can still access the files freely, read their content, but you can't execute them in ways of running an EXE file. This could be used to limit what programs can be run in what locations. Haven't tried this one yet so I'm basically talking theory for this one.

    I've run into an issue with Secure Folders (No-execution) function. It WAS working the past week or so but now it's not working and i can click on any executable that i put into any folder that has the No-execution SF flag and the darn thing runs anyway. Lock + Hidden still works and i haven't tested Read-only but No-execution is fell flat on it's face for some reason. Yes within the program it is ENABLED but is NOT preventing a manual starting of the executable whatsoever.

    REVISION OF ISSUE POST: Duh, my bad i guess. I had Explorer.exe in the TRUSTED APPLICATIONS list. THAT was allowing any executable i placed in a SF protected folder to run it anyway. Removed the checkmark from off Explorer.exe line and now SF is preventing execution as expected.

    Thanks for your experiences. I'm still awaiting for the dev to come over.

    Can anyone with Windows 8 confirm my most recent experience about the No-execution feature not working whenever you have Explorer.exe in the TRUSTED APPLICATIONS LIST? And then after unchecking or removing it those same executables listed as No-execution in that TAB works again normally as expected. This is no biggie at all now but just glad that i toyed with the SF settings long enough this week to realize what works and what doesn't on my machine.

    Whether I have explorer.exe or not in the TRUSTED APPLICATIONS LIST, an exe I tried to run was blocked by Secure Folders in No-execution mode, on Windows 8.1, admin account, UAC off

    Ok thanks. I am on plain jane Windows 8.0 OEM so it's likely just a small difference due to versions/updates or whatever. I just found it strange when SF allowed launching any exe that i deliberately placed in a protected SF folder in No-execution mode. Removing explorer.exe from the TRUSTED APPLICATIONS list returned SF to a working state again on that one.

    That's why we need per rule trusted apps. So trusted apps don't conflict with other rules, potentially negating them. I have the same issue with documents protection where I need explorer.exe there in order to still use them.

    I confirm (Win7Ux86). @EASTER, when the UAC (i assume you keep it enabled) popped up, did you allow the elevation?

    Ran some quick tests.

    DENY EXECUTION ON FOLDER OR FILE (same results)

    a. "Trusted" Explorer: depending on the test-exe's Zone Identifier, either

    1. UAC prompt ->Yes-> noexec.JPG , or

    2. "Do you want to run this file" box->Run->UAC prompt->Yes-> error5.JPG


    b. un-"Trusted" Explorer: depending on the test-exe's Zone Identifier, either

    1. noexec.JPG , or

    2. "Do you want to run this file" box->Run-> noexec.JPG


    PS. The bad news are that, despite
    SF's anti-execution doesn't work on .msi files.

    Has anyone tested some crypto-malware in Locked mode?

    Not specifically, but I've tested with Read only on my other two internal drives, and nothing can write to them, so that should also protect against crypto.

    Good to know. Anyway I'm going to test some crypto in Locked-mode but explorer.exe as trusted application... just to be sure.

    @CGuard My bad, but it should be better clarified that earlier when testing the No-execution function on those SF folders, that specific test was 100% UAC turned off. So it's nice to know that with UAC off that SF is indeed providing the expected protection.

    Hi All

    I can confirm that Folder Protection with Secure Folders does NOT work when in virtualised mode with Shadow Defender. It DOES work with Shadow Defender outside of virtualised mode.

    Well that's strange. I have folders protected on my other two drives, and I am in shadowmode with just c: shadowed and secure folders works fine.

    Hi Peter 2150

    I was confirming in my post 92 what pegr said in his post 14

    """"blacknight said:
    Any know conflict with other security softwares ? It's a new program ?
    Not a conflict as such, but Locked folders on a partition shadowed (virtualized) by Shadow Defender didn't work when I tried it. The "Locked" folders on the shadowed partition was accessible by all programs.

    EDIT: Just to be absolutely clear, I should have added that on a non-shadowed partition, the Locked folders feature worked just fine.

  21. Secure Folders seems to use Windows ACL. When in shadowed mode the redirected writes do not touch the folders protected by SecureFolders, so SecureFolders allows access. :D

    See for example my quick backup drive protected by Access Control List (at night when internet goes down, my NAS is awakened and starts backing up data of all network connected PC's). Quick backup only backs up my documents. Desktop is the user with only read access. When a ransomware is started by a medium level process, it is blocked (UAC elevation request will be triggered). Secure Folder uses so little CPU, it has to be using build-in OS-protection mechanism.

    Any news on this program?
    Although it works great for me I'm still reluctant to embrace this program with complete trust because the author doesn't want to come over to this thread, apparently.

    This has been a concern of mine as well. While the program looks great and functions well, we have no idea where this is coming from. By that, I mean is there a larger company involved, what country is it from, are there plans for a paid version as well. I would prefer to understand the bigger picture here. The web site doesn't offer much detail on these things. The last time that I dug into this I believe it may be from Ukraine, although that could be wrong.

    The last time I talked to the developer he told me he was willing to sign up here and "participate in conversation" (8 days ago) but nothing so far.

    That would be fantastic if the developer was to participate here. I believe that there is quite a bit of interest here regarding Secure Folders and I see a lot of potential there.
