What are some common signs of a malware infection on a computer?

When a computer is infected with malware, there are several signs that can be observed. These include the presence of suspicious network traffic, unauthorized access to files or folders, and the sudden appearance of encrypted files demanding ransom. Another indicator is the modification of system files or registry entries, which can lead to system instability. However, engaging in activities related to malware infection is illegal and unethical.
