Although the translation is poor, it indicates an email attachment as the means of delivery and care has to be taken with any email attachment, especially unsolicited or unexpected (even from friends email addresses, they can be forged) and never open them from the email, save the attachment to your hard disk without opening it and upload it to a multi-engine AV scanner at:
VirusTotal - Multi engine on-line virus scanner Or
Jotti - Multi engine on-line virus scanner if any other scanners here detect them it is less likely to be a false positive.
Help prevent or limit damage by denying permissions. Whilst browsing or collecting email, etc. if you get infected then the malware by default inherits the same permissions that you have for your user account. So if the user account has administrator rights, the malware has administrator rights and can reap havoc. With limited rights the malware can't put files in the system folders, create registry entries, etc. This greatly reduces the potential harm that can be done by an undetected or first day virus, etc.
