Hello,

The first step to getting a remover for the malware is to submit a copy of it to ESET's virus lab for further analysis. Instructions to do this can be found in ESET knowledgebase article #141, "How to submit virus or potential false positive samples to ESET's labs." In the Subject: include the text "Cleaner Needed" and in the body of the message include a link to this message thread, along with your contact information (name, email address, alternate email address, telephone or fax and so forth) in case the virus lab has a question.

Regards,
