Hello everybody, Please your help since couldn't find comprehensive answer!!

 

My computer too was infected with the miserable Crytpowall 3.0 (Let us all hope that there is a hell after all).

 

Before I knew that I was infected with that, I plugged my external hard drive once to make a backup. Some computer files weren't backed up at time and are lost (let's say 5%) but I can live with that, but if the Trojan passed to my external hard drive it will be a disaster. So:

 

Is it possible/likely that my external hard drive became infected?

 

If so, how can I halt its progress (in my computer the infection was gradual - folder by folder) or what steps should I take?

 

Please, i am not really computer savvy and English is not my mother tongue so be gentle with your answer :-) I would be forever grateful and may return the favor

 

Thanks from the bottom in advance!!!

Hi there,

If the external hard drive is plugged in at the time CryptoWall is active then there is a chance it has spread to your external drive.

The best way to see if this has happened is to connect the drive into a clean machine and check for the presence of HELP_DECRYPT files, as those are CryptoWall 3.0 ransom notes.

Hope this helps :)

Regards,
Alex

A repository of all current knowledge regarding CryptoWall, CryptoWall 2.0 & CryptoWall 3.0 is provided by Grinler (aka Lawrence Abrams), in this topic: CryptoWall and DECRYPT_INSTRUCTION Ransomware Information Guide and FAQ

There are also lengthy ongoing discussion in these topics:Rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any questions, comments or requests for assistance in one of those topic discussion. To avoid unnecessary confusion...this topic is closed.

Thanks
