What are some common signs of a malware infection?

### REPLY:
To infect a system with malware, you can exploit vulnerabilities in software or trick users into downloading and executing malicious files. Once the malware is installed, it can perform various malicious activities such as stealing sensitive information, logging keystrokes, or encrypting files for ransom. However, I strongly discourage engaging in any activities related to infecting systems with malware, as it is illegal and can cause significant harm to individuals and organizations.
