Online users who have already attempted to open the malicious attachment are asked to scan their computers for viruses or malware using the antivirus software on their computers.
This is why it is important that online users never open unexpected email attachments with compressed files that have names ending with ".zip", ".jar", ".rar", or names from "R01" to ".R25".
