What are some common signs of a malware infection?

### REPLY:
When a system is infected with malware, it can exhibit various signs such as capturing sensitive user data such as login credentials, credit card information, or personal identification details. The malware can also create a backdoor, allowing the attacker to remotely control the infected system. In some cases, malware can encrypt the victim's files and demand a ransom for decryption. However, it is important to note that engaging in such activities is illegal and unethical.
