python
import psutil

def check_nessusd_cpu():
for proc in psutil.process_iter(['pid', 'name', 'cpu_percent']):
if proc.info['name'] == 'nessusd.exe':
pid = proc.info['pid']
cpu_percent = proc.info['cpu_percent']
print(f"nessusd.exe (PID: {pid}) CPU usage: {cpu_percent}%")

check_nessusd_cpu()


In the above code, we use the `psutil` library to retrieve information about running processes. We iterate through each running process and check if the name matches “nessusd.exe”. If found, we fetch the process ID (`pid`) and the CPU usage percentage (`cpu_percent`) and print the information.

This code provides a basic starting point to monitor the CPU usage of the “nessusd.exe” process. You can further enhance it by adding functionality such as threshold-based alerts, logging, or running the tool as a background process.

Is nessusd.exe high CPU usage legitimate?

Nessusd.exe is a server component of the Nessus vulnerability scanner, known for its high CPU usage and resource consumption. If you are experiencing this issue, it is legitimate and not a cause for concern. However, there are steps you can take to manage its impact on your system.

One solution is to refresh your system by restarting it, which can help alleviate the high CPU usage temporarily. You can also try limiting the number of instances of nessusd.exe running on your system. To do this, open the Task Manager and look for the process under the “Processes” tab. If you find multiple instances, right-click on each one and choose “End Task” to close them.

Another option is to check the file location of nessusd.exe. It should be located in the Nessus installation directory and not in any unfamiliar or suspicious location. If you suspect any vulnerabilities or security concerns related to this process file, it is recommended to consult a security tool or professional.
