Threat Description



Aliases: Crypto
Category: Malware
Platform: W32


Win32.Crypto is an interesting virus from technical point of view, but it's not spreading in the wild and thus not a cause of concern for the end users.

Crypto infects EXE and DLL files and spreads when these are exchanged between machines.

The most interesting part of the virus is that it encrypts data on the hard drive with real-time on-the-fly encryption. So, if you remove the virus, your data is left encrypted. Encryption is done with Microsoft's CryptoAPI.
