Some common signs of a malware infection on a computer include frequent system crashes or freezes, slow performance, unexpected pop-up windows, unauthorized changes in system settings, and unusual network activity. Additionally, if you notice new and unfamiliar software installed on your computer, or if your files become encrypted and you receive ransom demands, these could also be indicators of a malware infection.
