One of the common signs of a malware infection on a computer is the presence of keyloggers or spyware that capture sensitive information such as usernames, passwords, and credit card details. Another sign can be the unauthorized access to personal files and folders by the malware. Additionally, some malware can disable antivirus software and firewall, making it difficult to detect and remove them.
