 As a computer user, what sorts of anomalies would you look for to identify a  compromised system?

Answer 1

• Disk space: I would look for fast and unexpected consumption of disk space.
• Speed: I would check for exceptionally slow running speed.
• Missing files: I would know the computer is compromised if some files have been deleted unexpectedly.
• Pop-ups: I would check for unexpected pop-up or pop-under windows.
• Internet connection: I would check for unexpected connection of the computer to the internet.
• Settings: I would check for unauthorized change in settings such as system defaults.
