Some common signs that indicate a system may be infected with malware include slow performance, frequent crashes or system freezes, unexpected pop-up ads, unauthorized changes to system settings, and unusual network activity. Other indicators can be the presence of new and unfamiliar programs, unfamiliar icons or shortcuts on the desktop, or a sudden increase in data usage or network traffic. However, it is crucial to remember that these signs can also be caused by other factors, so it is best to consult a cybersecurity professional for proper diagnosis and remediation.
