Some common signs of a malware infection on a computer are the sudden appearance of unknown processes in the task manager, an unusually high CPU or memory usage, and the presence of suspicious files or folders in system directories. Another sign could be the modification of system files or registry entries. Additionally, malware infections can lead to unauthorized access to sensitive information like passwords or credit card details, which may result in financial loss or identity theft.
