Some common signs of a malware infection on a computer include the presence of keyloggers, which can capture sensitive information such as passwords and credit card details, unauthorized access to personal files and folders, and the encryption of files with a ransom note demanding payment for decryption. It is important to avoid visiting suspicious websites and downloading files from untrusted sources to prevent malware infections.
