    I don't know why these files are created on C: but normally files which are modified/deleted on D: should appear in the folder D:\Backup(AppCheck)\ (or at least on the same partition on which these files are being modified)

    At the time of file modification it is acquiring more information and if AppCheck is detecting "abnormal behavior" it is copying the file to the Ransom Shelter and continues to monitor the file modifying process.
    In the case of Ransomware it can easily restore damaged files.
    The "disadvantage" is, files modified by the user or by legitimate applications might also appear in the Ransom Shelter.

    But not all modified files with a "protected extensions" are sheltered. If the CARB engine can't see "abnormal behavior" it doesn't even copy the file to the Ransom Shelter.
    Sometimes it "needs more time" to analyze it, copies the files to the shelter and is then monitoring the file modifying process.
    You/(the email program) probably have modified these files else they wouldn't appear in the Ransom Shelter.

    "I have 5 .pst files. Why only 2 (or 3, I do not remember) of them were backupped?"

    Only modified files are backupped (but not all, it depends - see above), other unmodified files are not copied to the Ransom Shelter.

    Is the email application copying the .pst file to a temporary directory (located on C: and is then modifying it?
    This could explain why AppCheck is copying the file to C:\Backup(AppCheck)\ and not to D:\Backup(AppCheck)\

    Email app is Office Outlook. The program is located in C:, the mail folder, for all the .pst files, is on another partition. So the presence of backupped files on C: remains unclear.
    I understand, though it remains a little bit 'mysterious' !
    Thanks to help me to understand this tool.
    So far I'll stay without shelter, my risks are small. And the cohabitation with Ransomfree is peaceful and gives me an extra layer of security.

    It has a cleaner now that scans and auto cleans and removes any bad stuff it finds. That sounds kind of scary to me, so i unchecked everthing that it could scan for.

    Hmm ... yes, I agree auto-clean, without the option to 'uncheck', is not for me. So I have done the same.

    I did run it for a short while, but then stopped it when I saw some of the (unknown) stuff it said it would remove ...

    Though as long as the clean is manually intitiated only, without any automated scheduling, one should be OK.

    I think they may be making a mistake by adding too much functionality to what was intitially a dedicated anti-ransomware app only. I had unticked other protection options (exploit, MBR) also, as I have this covered by HMPA.

    Malware/Ransomware might have modified the registry in a malicious way and these modifications can be removed now. Now malware/ransomware is removed "fully".

    OK, that makes sense mood. But can you confirm ... there seems to be no way of 'unchecking' an item marked for removal?

    Interesting stuff, at the moment I'm not using any scanner at all, so I could use this. Let's hope it will remain stable.

    They should indeed stop with adding more features, but if it remains stable and if you can turn things off, then it's fine with me.

    If it finds something it will be removed automatically.
    You have the choice to untick certain options prior running of the cleaner but yes, there is no screen like: "do you want to clean these detected items? (yes/no)"

    The average user might not even know what "HKLM\System\CurrentControlset\Services\AppztestZ" means and can't decide if certain items should be removed or not.
    Can be one of the reasons why they have decided to have AppCheck clean detected entries automatically (no further action is required by the user)

    ...but nevertheless a confirmation prompt or something similar could be useful (for reviewing of all detected items / for deselecting of wrongly detected items)

    Has no one spotted the following 2 lines below? They might reassure users:

    "You may find out more information about the scanner results after the scaning process is completed. This can be found in the threat log of AppCheck tool, which also provides restore function for removed items."

    Regards, Baldrick

    I don't see any restore function for the 4 things that were removed from my registry before i had a chance to cancel the scan.

    You are right. Right click task bar, Tools>Quarantine, right click item gives an option to restore.

    Edit: After imaging, ran a series of scans, ticking extra options each time. Removed 16 items altogether (adware, plus I suspect some 'benign' malicious applications and system modifications), but all seems OK so this new feature looks usable.

    Not for me. I ran a scan and it deleted 4 registry items but there was nothing in Quarantine for me to restore.

    Same thing happened to me. Soon after the scan started, it showed that 4 registry keys were removed without asking me about it.
