Our Systems Have Detected Unusual Traffic From Your Computer Network
I was recently working on a project when I received a message from my internet service provider (ISP) stating that they had detected unusual traffic from my computer network. I was immediately concerned, as I had not made any changes to my network or computer recently. I decided to investigate the issue further to ensure that my computer and network were not compromised.
After some research, I discovered that the message I received was a common warning from ISPs when they detect suspicious activity on a user’s network. This activity could be caused by a variety of factors, including malware, viruses, or hackers trying to gain access to your computer or network. In my case, the unusual traffic was caused by a virus that had infected my computer without my knowledge.
What is Unusual Traffic?

- Large file downloads or uploads that consume excessive bandwidth
- Unusual network scans or probes
How to Identify Unusual Traffic
Identifying unusual traffic can be challenging, as it often involves analyzing large amounts of network data. However, there are some common indicators that may suggest unusual activity, such as:
- Sudden spikes in network traffic
- Unusual patterns in network traffic, such as traffic at odd hours or from unexpected sources
- Connections to suspicious or unknown IP addresses
- High levels of dropped packets or connection errors
- Slow network performance or frequent disconnections
