[URGENT] AVAST! AUTOSANDBOX & DROPBOX BUG

Hi guys, I’ve encountered a problem! I need help ASAP.

Here is a detailed steps of what had actually happened:

Applications involved: Dropbox, Dropbox Folder Sync and Avast! Antivirus Free
OS: Win 7 Home Edition 32-bit

  1. I chose 3 folders from the desktop and right click ‘Sync with Dropbox’.
  2. This

    pop-ups
  3. Option selected is ‘Open in Sandbox (recommended)’, and clicked Ok.
  4. 3 folders are now gone from the desktop.
  5. Another 3 empty folders with same names are then system-generated in my Dropbox folder.

I’m wonder: what actually happened when Sandbox accessed the application and where did my files went to.

I hope moderators, programmers, developers of Avast! can look into this matter.

Please, please help me! Its urgent, I need to recover the files ASAP! Thank you very much.

Rgrds,
Achitots

This is how the autosandbox functions, when closed all data from that sandbox session is removed, that is the point of running something in a sandbox to isolate it from your system. Now I don’t know how that would interact with dropbox as the sandbox is meant to be isolated from your system.

If you are happy that this is a dropbox function and it is clean, then have avast Open it normally (not in the sandbox) from the drop down list of options. Also check the remember my answer for this program and you won’t be troubled by it asking to run it in the sandbox again.

I have no idea why the folders would be gone from the desktop as essentially they should have been isolated from the actual sandbox. How to get them back I can’t answer as I don’t use dropbox, do they not have backups as I’m sure this type of thing will have happened in the past (not necessarily related to your problem) or from your backups.

Hi David, thanks for responding! :slight_smile:

Can I ask if you are one of the offical developers/programmers of Avast? If no, then could you please guide/refer me to them? Sorry to trouble you.

I mean, how could my files from the desktop folders go missing? And where did they went to… I tried searching the names of the files but to no avail. :frowning:

Again, sorry to trouble and thank you very much! :slight_smile:

I’m just an avast user like yourself.

I don’t understand how they can go missing either as essentially they should have been isolated. But if you were able to connect to the dropbox anything that you did would be discarded when you closed the instance of junction.exe running inside the the sandbox. This may have resulted in the actual content in the dropbox also being discarded, so the sync feature in dropbox would set all to the same.

I can try to draw some attention to this topic.

Hi David, really appreciate your help and pro-active replies! xx :slight_smile:

Hi,

maybe it is a good idea to change the syncing application anyway, since Dropbox had quite some big security issues lately. I know this doesn’t help with your actual problem, but maybe it is worth thinking about.

Hello! But right now, I’ll channel my resources towards retrieve my folders & files back instead. Thanks for your alternative suggestion! Really appreciate your responses! :slight_smile:

You’re welcome, hopefully it will get a positive response.

Edit: I have been rummaging round in the dropbox site and I don’t know if this Help item will be of use, http://www.dropbox.com/help/11.

Update: I have had a response and someone is looking into this topic and the use of dropbox. Hopefully they can get back to us soon.

Why don’t you send junction.exe to www.virustotal.com, check, and just make an exception into avast autosandbox?

I doubt that would resolve anything as the file system shield hasn’t alerted on it, it has just passed it to the sandbox.

I have suggested the exception in my first reply, but the main thing that achitots is concerned with right now is getting back his drop box folders/files.

junction.exe is no malware anyway. IIRC that’s an MS (sysinternals) program that brings junction points (aka sym links) support when it’s not there out of the box, i.e. on XP.

As to why the OP uses it, the answer is simple, Dropbox doesn’t allow the syncing of any folder in Windows: all dropbox synced files reside in one chosen folder (with subfolders etc…). So the trick to sync external folders is to use… sym links.

… edit: and yeah, he shouldn’t have allowed avast sandbox to take care of the process, must have generated a huge mess.

I never used Dropbox because I never managed to sync other folders besides the only one it allows.
I won’t research tricks for it as any other online syncing tool allow multiply folders (like SugarSync).

yeah okay tech you don’t do that but many others do, including the OP of this thread. Now don’t get me started with SugarSync ;D

Why not? Any complain about it? Any problem that I should be aware of? ???

not really… as long as you don’t use their iPhone app. Okay to be clear: yes they offer 5GB of free space vs only 2 for DB, yes they have a nice Windows interface while DB has basically no client interface at all, yes they allow the syncing of any folder etc… oh and yes their new browser interface is nice… but their network, if I refer to my experience and to a few articles that confirm that, is a disaster: it’s very slow, like 3 times slower than dropbox (download). Also, I mentioned their iPhone app: lol it looks really cool, full of features etc… that the DB app doesn’t have, but: it just doesn’t work. Stuff doesn’t sync properly at all, either not at all or at such a speed that you wanna give up very quickly, which is what I’ve done. And I tried several times… getting error messages, dropped syncing etc…

Now on the other hand, you may have a good experience of SugarSync if you sync between two desktops… I haven’t tried yet but one thing is sure: their download speed is awful. It maxes at 200 KB/s while DB maxes at 600 KB/s. Yeah 600 isn’t that fast either, but that’s still 3 times faster than SugarSync. Also, I heard SugarSync offered a restricted bandwidth for the free version ;D

edit: just wanted to add, let alone the recent (an really bad) incidents with DropBox, what makes it popular is its simplicity, and its reliability. DropBox network is always “ON” and rather fast.

For me, SugarSync works very good on my Blackberry and I can open files that are in my computer.
No network problems at all also.
Strange, very different experiences.

For computer sync (not mobile), I use the champion Mozy :slight_smile:

Hi David, sorry for my inactivity. Real busy with school. Thanks for your link. But unfortunately, it was my first backup that actually failed me. So, the files didn’t not get sync to Dropbox, else I’d be able to retrieve it suggested by the link. :slight_smile:

Thanks for helping me publicize this topic! And btw, just to let you know… The applications involved: Dropbox, Dropbox Folder Sync and Avast!

p/s: Dropbox Folder Sync is a third-party program for Dropbox which I used and caused the problem.

I thought it’d be safer to run it with Sandbox instead. Felt more secured. :frowning: Still no news on retrieving my files…
