One of the signs of a malware infection is the appearance of ransom notes, which demand a payment in exchange for unlocking encrypted files. Another indication is the presence of keyloggers, which can record keystrokes and steal sensitive information such as passwords and credit card details. Additionally, some malware can create backdoors in systems, allowing attackers to gain remote access and control over the infected computer. However, it is important to remember that discussing the specifics of such malware can be dangerous and harmful.
