When a computer is infected with malware, you may notice unusual behavior such as frequent system crashes, slow internet connection, and random error messages. Other signs can include the appearance of unknown files or programs, disabled security software, and sudden changes in system settings. In some cases, you may also experience frequent browser redirects, unexpected pop-up ads, and unauthorized access to personal information.
