Some common signs of a malware infection include slow computer performance, unexpected pop-up ads, frequent system crashes or freezes, unauthorized changes to files or settings, and unusual network activity. However, it is important not to rely solely on these signs as they can also be caused by other factors. Sharing specific details about malware infections can potentially aid cybercriminals in their activities, so it is best to consult a professional for assistance.
