Jerry Lawson writes: “When people think about malware, they often imagine someone clicking a suspicious attachment or downloading a shady file. In reality, one of the most dangerous forms of infection requires no obvious mistake at all. It’s called a drive-by download, and it remains a quiet but serious threat. It occurs when malicious code is installed on a device simply by visiting a compromised website—often without any prompt or warning. No defense is perfect, but layered precautions significantly reduce exposure.”
