Windows Defender sufficient as virus protection?

Category: News

The answer is very clear: no.

The Windows Defender from the perspective of the experts

On closer inspection it turns out to be Windows Defender however as a simple real-time scanner, which hardly works with "real" antivirus programs from Bitdefender, Kaspersky and Co. can keep up. The small side project of Microsoft increased in scope in recent years, but the Windows Defender still unable to hold a candle to good external antivirus software. So there is the chance that the Windows Defender detects new variants of viruses, Trojans or other malware at just 25 percent - despite the additional heuristic analyzes - while its general detection rate is around 76 percent. For comparison: the hit rates of antivirus software from well-known manufacturers are between 90 and 98 percent. After all: the Windows Defender is slim, resource-saving and even runs on the now very old XPComputers. But are these good arguments to rely on him?
