When does Windows Defender scan?
If I download an exe file from someplace, does Defender scan the file immediately for possible problems or do I have to request the scan?

Welcome to Windows TenForums, Alfred71.
I can only attest using IE11. Although not absolutely sure, I believe other browsers use the integrated download manager. Defender does indeed automatically scan any type of file that one downloads when finished.
Download Manager - Microsoft Windows

Thank you, that fully explains what I wanted to know.

Doesn't prevent browser hijackers, I know that for a fact!

A lot of life is trial and error. We listen to suggestions when there is a good one presented and/or failures when they are well explained instead of one-liner bashing of a product without explanation or proof.
Here’s another one for the OP > Never turn off SmartScreen Filter in IE.

I was searching for a ESD to ISO not knowing of the one here yet. I found one at Dev-Host the file sharing site, a site where I've downloaded many files in the past for a now obsolete tablet. A ran the app, some kind-of downloader app appeared on my desktop and I removed it. I opened Chrome and I get a popup from "m.zhmlie.com" that my Java needed updating, click here. I closed it but it popped again, sometimes I could close Chrome before it came back, sometimes not. Open Chrome again, popup returned from "3b.zhmlie.com". After another cycle, a new window opened with audio, contact our reps to help you with your computer problems. I closed everything, ran Defender Quick scan, found nothing. Ran MBAM, found 39 objects, deleted all, opened Chrome and popups still came up.
Since I had made a PVHD backup using Paragon HDM15S a few days before, I restored to get rid of it. The very first time that I had to use a Paragon backup for that purpose.
I wouldn't even mention this but since people are being told that Defender is all you need, I spoke out. My first infection in four years.

Let’s see > You “ran Defender Quick scan”, But “Ran MBAM” full scan? Which then found the culprits? Why didn’t you run Defender full scan? Another thing > Does Chrome have SmartScreen Filter? IE is important in that area.
I’ve had two instances of a virus since using Defender in its infancy way back in early W7 when they introduced MSE. I never thought or think today that any AV is 100% effective, but I’ll put Defender up against any AV product. What AV is 100% that it does catch everything? When you can answer that let me know.
Like I stated > A lot of life is trial and error. I’ll bet you don’t download from that site again. Obviously they can’t be trusted. I wouldn’t trust any of those file sharing sites. In fact I was in an 8F member’s site yesterday looking for a free small utility for my 10 that he introduced for 8.x, although I had the install of it on my 8.1 partition. I was curious to see how he was doing with his site. It grew in the past year and a half with all sorts of software and what I would consider to be some malware. As soon as it directed me to another page flashing “Download this” and “Download that” I was immediately out of there. I went into my 8.1 partition to get the utility.
This only goes to show one more time that WE are our best AV along with keeping a mirror of our system as I see you so wisely do.
BTW, Welcome to Windows TenForums. Enjoy your stay. :)
