Chello.at ignores virus reports for two months

Last updated: 2004-06-21

Current virus senders do not leave an email address that one could contact. The only trace a recipient can follow to track down the sender is the sender's IP address. From that the ISP responsible for the address range can be determined. However, if the ISP is notified but ignores such notifications or for other reasons takes no action, there is nothing that can be done. The virus send will remain unaware he/she is sending out viruses on a daily basis and more and more computers will get infected.

We are receiving viruses from a particular customer at chello.at, a major Austrian ISP for two months after first notifying the company. At this time we still have not received any response from their abuse department.
