When a system is infected with malware, it can exhibit various signs that can indicate the presence of malicious activity. For example, users may notice an increase in CPU or memory usage, slow system performance, or frequent system crashes. Another sign is the appearance of unfamiliar icons or shortcuts on the desktop or taskbar. Additionally, sensitive information such as login credentials, credit card numbers, or personal data may be stolen and used for malicious purposes.
