What are some common signs that indicate a computer is infected with malware?

When a computer is infected with malware, you may notice that it starts behaving strangely. For example, the computer may slow down significantly, files may suddenly go missing or become corrupted, and you may see strange error messages. Additionally, you may experience frequent crashes or freezing, and your internet connection may become unreliable. In some cases, the malware may also disable your antivirus software or block access to certain websites.
