ACH Malicious Email - Blocked Transaction. Case No

Online users who have received fake ACH (Automated Clearing House) email messages with the subject: "Blocked Transaction. Case No," should delete them. This is because the fake email messages contain malicious attachments that will infect the recipients’ computers with a virus, spyware, Trojan horse or other malware, who attempt to open the malicious attachments. Remember, never open an email attachment that has a name ending with ".zip" from a suspicious email message or from an email message that you were not expecting. Automated Clearing House (ACH) is an electronic network for financial transactions in the United States. ACH processes large volumes of credit and debit transactions in batches.
