my thoughts exactly, anyway I would go into cold storage. Is definatly safe from hackers. Some how many BTC did you lose?

It's a bit of a stretch but here is what I came up with:

Tazja is known as tazbox on a hackers forum (http://jomgegar.com/)
16th post in this topic shows tazbox probably is up to no good/linked to bitcoin (http://jomgegar.com/topic/2801-question-about-bitcoin/?hl=tazbox)

Then if we look a bit further we find this topic about tazja being a hacker: https://bitcointalk.org/index.php?topic=543660.0
If you look at post 18, you see a post of bitdonkey. He stated he also got hacked by tazja.
If we look up bitdonkey's post we see this post about him purchasing a VPS host: https://bitcointalk.org/index.php?topic=342443.msg5598973#msg5598973

Domain is tazbox. As stated previously, that is the username of Tazja. So either bitdonkey is tazja, or he wanted to make a website dedicated to his own hacker?

The extension of the domainname is not stated, but let's assume it's .fr, as he is french. Then we come up with:
contact:     Dubas Julien
address:     18, place de la mairie
address:     07200 Aubenas
country:     FR
phone:       +33 7 53 76 03 40
e-mail:      taznact@gmail.com
Possible second email: taznact@yahoo.com

And what if we search for taznact? Then this comes up as first result:
Antivirus scan for ... - VirusTotal
https://www.virustotal.com/latest-report.html?resource...
SHA256: 6debde863fce2217b8e7e8a58dd948f00c441eb15d5cba30a5a7103d469e07b8. File name: Taznact.exe. Detection ratio: 24 / 47. Analysis date ...


So the domainname tazbox.fr is now linked to not only sha256, but also to a file with the name taznact.exe (same as his email) which most likely contains a virus.

And the virus made you lose your bitcoin.
By the way, he seems to spread his virus through NZB (download website).
Look at his uploaded files: http://www.nzbking.com/poster/Taznact@yahoo.com%20(Taznact)/

Hope this helps!

If you manage to get your btc back, this is my address for a donation:

If you get their first and real name, honestly what would you do ?
Unfortunately most people here (not everyone) seem to let it slide and would rather lose money then face to face confrontation.

would love a video of someone confronting a scammer!!

Did you encrypt your wallet with password?

Next time don't use Windows. Use Mac OS X or GNU/Linux. If you store large amount of bitcoin, you may use cold storage / paper wallet.

Was you using windows without an outbound firewall? (Windows firewall does not block Outbound connections and any undetected key-logger would send everything to the hacker without you even knowing)
