Windows 10: Windows Defender found a virus after a full scan. Is it safe now? What file was it?

I ran a "full scan" with Windows Defender yesterday on my Windows 10 Samsung Laptop -- which is updated every time there's a new update. Here's the result:

Exploit:Win32/Pdfjsc.Q (Severe)

9/26/2020 7:28 AM (Active)
​

I immediately clicked on "Start actions" and disconnected from my Wi-Fi. I believe this came from one of the PDFs (from different sources) I downloaded a few days ago. I don't know if I actually "ran the virus" (a.k.a. opened the infected PDF) or if Windows Defender found it despite the fact that the infected PDF has never been opened.

I'd like to know a few things:

[1] Did Windows Defender actually handle the virus? Meaning, is it safe to connect to my Wi-Fi and use my PC as usual?

[2] How can I find the specific file that triggered this? If you see the three images I posted above, Windows Defender does not show which file/path this came from. Knowing this would be really really helpful because I wanna keep my other PDFs, though I'd probably delete the infected one.

[3] Should I format my PC?

[4] What does "9/26/2020 7:28 AM (Active)" this active flag mean? Was the virus running in the background on my machine before I ran a full scan?

Thank you!!

How to scan anti-virus with windows Defender?

For windows 10, I would like to know on how to scan anti-virus with windows Defender, when I select a file and right click, there is no anti-virus for scanning for windows defender and how to make windows defender update automatically?

Does anyone have any suggestions?

Thanks in advance for any suggestions

 

Windows Defender realtime scanning will not switch on - it detects another anti-virus product.

Windows Defender realtime scanning will not switch on, and the message suggests there is another anti-virus product present but if there is it does show up in Window 10 UI.

The long story is that I am troubleshooting a problem with application software. The manufacturer suggest removing Bitdefender because there product is incompatible. I thought I would give this a try, if only to element Bitdefender as a cause.

Firstly, I upgraded from Bitdefender 2016 to 2017 to see if that made a difference. The application still failed so I decided to try removal.

• I used the standard uninstall to remove Bitdefender 2017, rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection
• I download the uninstall application for Bitdefender 2017, ran it then rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection
• I checked the file system and all Bitdefender files have been deleted.
• I check the registry and found a couple of references to Bitdefender Wallet, then deleted these.
• I rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection
• I reran the uninstall application for Bitdefender 2017 then rebooted but Windows Defender would not start realtime protection because another product was providing realtime protection.
  

I can find no traces of Bitdefender so I wonder why Windows Defender detects another anti-virus software. I've check other posts but couldn't find additional steps for uninstalling an anti-virus software. Any suggestions?
