Malicious encryption programs

Recently we’ve noticed several versions of one malicious program spreading. The program encrypts users files. In the last week we’ve had more requests from users to decrypt encrypted files.

An de-encryption routine has been added to antivirus databases for encrypted files. The encrypted files are detected as Virus.Win32.Gpcode.

The string PGPcoder is in the beginning of encrypted versions of files.

On PCs with encrypted files users may find files which contain warnings in Russian. In translation, the warnings say:

The contents of some of your files have been encoded using encoder ver 1.2. For decoding contact the following address: xcv789@mail.ru

Some of your files have been encoded using CRZ. For decoding contact: bnm7814@yahoo.com or ztc567@mail.ru]
