[QUOTE="ForgottenSeer 89360, post: 913952"] The argument about "Protection" is invalid in this case. Microsoft provides many layers of "protection", such as core isolation, exploit prevention, SmartScreen, parental controls and firewall. All these features are totally independent from Microsoft Defender. Defender itself is merely an antivirus + ransomware protection. Due to this fact it's wrong to even use "protection" as a term when talking about Defender. The right term is raw malware detection. Defender offers great malware detection that would hardly fail for the average user, even if no configuration utilities were used. Remediation of threats includes removal of all files created by malware, as well as removal of registry entries/keys. Common settings "touched" by malware will be restored to safe defaults. A rescue environment is also offered, allowing users to remove stubborn malware via booting to another microsystem. The engine provides great classification for people looking to find out what exactly hit them. However, the product comes with a great performance hit. Software launch and installation causes >40% CPU spikes on my high-end system. Upon uninstalling a third party AV (pretty much any AV with the exception of Trend Micro) day-to-day tasks feel much more sluggish. Product has too many FPs. Upon detecting a threat, a weird behaviour can be observed. First, Defender prompts user to take an action. Once you bring the UI and try to exclude the file, by the time you select the action, click "apply" and answer the UAC prompt, Defender has already made the choice instead of you and removed it. Configuration is beyond minimal unless you either use a utility provided here, or you dive into the group policy editor. So to put it simply, will Defender detect just as much malware, as other big names - yes it will, and in some cases might outperform them. Is the overall performance of Microsoft Defender better than others? No, it is definitely not. [/QUOTE]
