Ok, this is a bit of a twisty story.
Soon after I bought my new Win10 laptop I started having PC freezes (nothing on the screen moves, incl. mouse) that in 4-30min resolved by themselves. I went back to using my old laptop until I resolve this blocking problem. I thought the problem might be caused by a virus, so I ran a "Quick scan" in Windows Defender (it found nothing) and a "Computer scan" in the free "Kaspersky Security Scan" app (it too found nothing).
Later, however, when I happened to do something minor on the new laptop, I noticed I have a notification in the "speech bubble" icon in the bottom right of the screen. I clicked the icon and in the pane popped up there was an item that said something like "Windows Defender: Blahblah was successfully..." (the message was truncated and unclear. This was several days ago, hence why I fill what I forgot with "Blahblah"). I clicked the message, it disappeared and the main WinDefender window popped up with nothing on it to elaborate on situation (in any of its tabs).
I'm thinking a scheduled Defender virus check may have found and removed a virus, and that's what the message may have been about, but I have no way to check. If it has indeed removed a virus, then very likely the cause of the freezes has been fixed and I can resume using the PC without having to first go through heavy procedures like this one.
How do I check if WinDefender has cleaned up any viruses?
Note: I don't want to just switch back to using the new PC for a couple days to see if any freezes happen, because if any freeze does happen during my work, it would be very annoying.
