Some common signs of malware infection include the presence of unknown programs or files on the computer, sudden changes in the web browser's homepage or search engine, frequent system crashes or freezes, slow system performance, and unauthorized access to personal information or accounts. Additionally, if the computer starts displaying unusual error messages, if there is a sudden increase in network traffic, or if the user experiences difficulties in accessing certain files or folders, it may indicate a malware infection.
