decrypt_instruction


Recommended Posts

Hello all,

 

Long time user but new to the forums.

 

My CIO brought in his laptop after returning from a user conference and has the dreaded "decrypt_instruction" lock on his files.  This is not his primary laptop so his business files are not on it thankfully, but this is the one that he uses for semi personal use that is company provided.

 

I've ran mbam.exe and I've attached the log for it, but also in research loaded up the Farbar tool and ran it and attached the FRST and Addition files.

 

I could really use some help on this one.  

 

Thanks a ton in advance,

 

Paul M. Fouts AAS,  A+, Network +, Ubiquiti Carrier Wireless Admin, Mikrotik MTCNA, CCDA, CCNA (Route/Switch, Security, Voice)

    Make sure you run ComboFix from your desktop.

    Give it at least 30-45 minutes to finish if needed.

    ---------->NOTE<----------

    If you get the message Illegal operation attempted on registry key that has been marked for deletion after you run ComboFix....please reboot the computer, this should resolve the problem. You may have to do this several times if needed.

    Double click TFC.exe to run it on XP (for Vista and Windows 7 right click and choose "Run as administrator") and once it opens click on the Start button on the lower left of the program to allow it to begin cleaning.
    Please be patient as clearing out temp files may take a while.
    Once it completes you may be prompted to restart your computer, please do so.
    Once it's finished you may delete TFC.exe from your desktop or save it for later use for the cleaning of temporary files.
