Installed on my system -
OS: Windows 11 Pro v 22H2 (Build 22621.382)
AV: Malwarebytes Premium v 4.5.13.208

I've been told this on another community website -

To stop receiving Security Intelligence Updates in WIndows 11 install another antivirus. This should turn off Defender and stop the definitions from being downloaded.

and

Malwarebytes is not an antivirus and will not shut off Windows Defender like an antivirus will. It is a malware scanner which is classed differently.

So is Malwarebytes an antivirus program??

In Malwarebytes, go to Settings->Security. Under Windows Security Center, enabling "Always register Malwarebytes in the Windows Security Center" will cause Malwarebytes to be your active AV/malware program, essentially "disabling" Defender. Defender will still be able to do scans but it will behave passively.

Malwarebytes is not an antivirus and will not shut off Windows Defender like an antivirus will. It is a malware scanner which is classed differently.

Malwarebytes is an AV replacement but I would recommend running them alongside each other if you have Malwarebytes premium.
The reason I recommend Keeping Defender on is the following.

Malwarebytes does not target script files during a scan... That means MB will not target; JS, HTML, VBS, .CLASS, SWF, BAT, CMD, PDF, PHP, etc.

It also does not target documents such as; PDF, DOC, DOCx, XLS, XLSx, PPT, PPS, ODF, etc.

It also does not target media files; MP3, WMV, JPG, GIF, etc.

Malwarebytes will block files like these if malicious on execution-only.

And,

Malwarebytes is not designed to function like normal AV scanners and uses a new kind of scan engine that relies mostly on heuristics detection techniques rather than traditional threat signatures. Malwarebytes is also designed to look in all the locations where malware is known to install itself/hide, so a full or custom scan shouldn't be necessary, especially on any sort of frequent basis (like daily), especially since the default Threat Scan/Quick Scan checks all loading points/startup locations, the registry, all running processes and threads in memory, along with all system folders, program folders, and data folders as well as any installed browsers, caches, and temp locations. This also means that if a threat were active from a non-standard location because Malwarebytes checks all threads and processes in memory, it should still be detected. The only threat it *might* miss would be a dormant/inactive threat that is not actively running/installed on a secondary drive, however, if the threat were executed then Malwarebytes should detect it. Additionally, whenever a new location is discovered to be used by malware the Malwarebytes Research team adds that location dynamically to the outgoing database updates so the locations that are checked by the default Threat/Quick Scan in Malwarebytes can be changed on the fly by Research without requiring any engine or program version updates/upgrades.

An AV will catch the file just by downloading it or just opening a folder with a detected file in it.

For example, if you get an email with an infected attachment, Malwarebytes will not even blink until you run it yet Defender will detect it if it is in their database without even actually clicking on it. Remember the list of files Malwarebytes does not target.

Then I will leave you with this.

As good as Malwarebytes is, it is just a layer of protection.

Using a browser that has Ublock Origin and the Malwarebytes Browser guard enabled is also a layer of protection.

Not opening attachments from an email unless you were expecting it from a specific user during a specific time period.

Do not use Torrents. Do not install every free software you find. Do not click links in an unknown email. Go directly to the site listed in the email.

Having a monthly image of your computer on an external drive that is only connected during the backup is actually better than any protective software ever made. Macrium Reflect free is the program I use and place on every computer I service

I've already done this. But I still receive these updates - the latest as I reply to your post!

Thanks anyway for your reply in confirming that MBW is an AV product.

Thanks for the comprehensive & informative explanation.
At the moment I'm taking daily images with MR Home and, together with the excellent information you have provided. I'll be running Defender alongside MBW from now on.
