I found a folder labeled "Crypto" through windows explorer in the c:\Microsoft folder in Vista. Is this the ransom ware or something else. The computer is currently not effected by it. Is it laying in wait? Appreciate the help.

There's no "C:\Microsoft" folder. Maybe you mean C:\ProgramData\Microsoft\Crypto? If so, that Crypto folder is totally legitimate. There's a few "Crypto" folders around Windows and they are required for the well being on your system as they are related to your certificates, so I suggest you to leave them be.

Hello,

Is the path you posted correct? C:\microsoft\Crypto?  

 

A legitimate folder is located at C:\ProgramData\Microsoft\Crypto.

 

As far as I know 'ransomware' doesn't wait. Last year, both my niece and a friend's laptops locked up without warning, and the "FBI" wanted $175 to allow them internet access again!  :hysterical: . I managed to get them online again, but it took some effort. (I actually know someone who paid..and it DID work!) 

If the path is right, and you aren't having any issues, it could be a program that created the folder. I looked and haven't found one that would put it there yet, though. If it IS a malware issue, you would want to post at... http://www.bleepingcomputer.com/forums/f/103/am-i-infected-what-do-i-do rather than in the Vista forum. If you are asked to run 'hijackthis' or some other malware log, BC wants you to post them here...http://www.bleepingcomputer.com/forums/f/22/virus-trojan-spyware-and-malware-removal-logs/

Oh and on top of what Mark said, no Cryptowares actually create a folder called "Crypto" so I wouldn't worry about that. It would be way too obvious that way. Usually, the Cryptoware drops a main executable that encrypt the files, and once done, it deletes itself and move on to display the ransom note.

Ransomware infections are created to alert victims that their data has been encrypted and demand a ransom payment.
