Hruu was created for the sole purpose to encrypt all popular file types. Rationally, as quickly as the file encryption is effectively accomplished, the users are not able to get access to them. Hruu virus adds its own “.hruu” to all the encrypted files. For example, the file “price_list.xls”, as soon as modified by Hruu, will be entitled as “price_list.xls.hruu”. When the file encryption is accomplished, Hruu puts its own special text file (_readme.txt) into all the folders that store the encrypted files.

The warning basically shows that the data has been encrypted and the only solution to get access to it is to use an unique standalone key. Regretfully, this declaration is absolutely true.
