Glitches in the matrix and Viber

I ran into an interesting problem with the messaging service Viber yesterday – I had a brand new computer which developed a fault rather quickly and which, prior to my returning it to the vendor, could not be made to operate in such a way as I could get at the data I had stored on it.

In theory, there was not much such data – I had not finished installing software on the machine, and nor had I started uploading backups from the previous machine to it. However, I had installed Viber and I had opened one conversation with a friend online. Six hours after I bought the machine, the operating system would not load and so it went back to the vendor.

I cannot fault the vendor in this case between their phone customer support and the behaviour of the staff at the branch where I did buy the machine. I was concerned though that the fault might be fixed at some point in their workshop and whether there was any risk that Viber would attempt to sync any subsequent discussions as I had been unable to de-install it before I handed the machine back. What was on the machine itself was low risk. I just wanted to ensure that Viber would not be able to subsequently sync with any subsequent conversations.

When you go looking for information on this front, the general assumption is that people have lost access to Viber on their phones and not necessarily to their desktops.

In theory, the two obvious solutions for the operating system loading error would have been replacement hard drive or reinstalling the operating system. I obviously could not do the the first, and the latter had been kiboshed by the fact that I had not even got as far as making a recovery disk. When I looked into it in detail, there is a theoretical fix involving rebuilding the BCD in the kernel. I found a single document which was detailed on the process but it did not, for example, outline what happened to any other data on the machine. As such, it did not leave me much peace of mind.

Viber is a handy messaging platform which you can use from both phone and desktop. Its user documentation is of mixed quality and, again assumes the reason you might want to nuke your Viber service is that you no longer have access to your phone. If you’re looking to deal with a desktop which has your account on it, it is actually possible.

When you set up Viber on your phone, you’re effectively setting up an instance of an account and any desktop installations of Viber are tied to that. You can, from the desktop installation, deactivate that particular desktop installation via settings. If you do not have access to the desktop installation, you MUST deactivate Viber on your phone and this will deactivate all Viber installations linked with that instance of an account, ie, Viber on your phone, viber on any desktops or tablets associated with Viber linked to your phone number.

You cannot pick them off remotely and individually. It’s all or nothing.

What happens then is that if someone tries to access Viber on any of the desktop installations linked with the account is a dialogue over whatever was most previously opened in Viber at the time of the previous synch, a dialogue box opens to tell you that the account is no longer active. They will have to respond to that dialogue box and in my experience, that kills the Viber data behind. There is a window of risk that someone might see something in your messaging software that you would not want, but at least there is an option for destroying the connection between your phone number and that desktop instance remotely, even if it’s the equivalent of a nuclear option.

The downside is that you lose all your messaging data unless you back the messages up before which you must do on your phone.

In short, assuming you’ve lost a non-phone device with Viber data on it, here’s how you kill things:

  1. Back up your viber messages on your phone if you want to keep them. If you don’t, you don’t have to do this.
  2. Go to the privacy setting and select Deactivate. You’ll probably have to scroll to the bottom to find it. This will kill your viber service on your phone and any associated non-phone installations (desktops for the most part).
  3. Set up viber on your phone again. I did not actually have to de-install, reinstall Viber on the phone to do this – it sent me a new 6 digit code and I was up and running.
  4. Set up viber on your desktop again by obtaining a new code. I did not have to reinstall Viber to do this.

I had to deactivate the machine remotely for some subscription software – MS Office and Adobe Creative Suite – and I could do this. I think it would be useful if, somehow, it was possible to review how many machines were receiving push notifications from Viber so that you could deactivate them at will rather than having to nuke everything and start from scratch.
