A computer infected with malware may exhibit various symptoms, such as the sudden appearance of strange files on the desktop, frequent system freezes, and unusual network activity. Additionally, you may notice that your browser homepage has been changed without your consent, or that your computer is running much slower than usual. It is also possible for malware to log your keystrokes and steal sensitive information such as usernames, passwords, and credit card details.
