Laptop: Dell Latitude E5570
O/S: Ubuntu 22.04 installed about two months ago.

Whilst running FireFox, Thunderbird and another application(?), the laptop virtually froze with the disk access light flashing manically.
I managed to start the system monitor (very slowly!) and it showed:

  • All four CPUs running at 80-97%
  • Memory: 99.7% of 8GB
  • Swap: 100% of 2.1GB
  • Network: unfortunately I didn’t make a note of that but I switched off the router, which made no difference.

After 10mins I hard rebooted (unwise?) and system monitor showed all back to normal.
Thoughts of malware spring to mind.
Comments/advice would be very welcome.
