You can, you did. The collective wisdom is to only have one antivirus/malware guard. This is not up to debate if you can, you did so that question is answered by you.
However, folk have complained of odd slowdowns to bluescreens so such a setup is never recommended.
2. Too many scans.
I have to write no. Today, now and for the foreseeable future there is no one scan that finds all the pests. Read

3. I am not going to comment about playing with fire.
4. Trojans. Since they have pretty much free reign, damage can run deep. My only comment is they can be bad news.
That said, I haven't gotten a virus in maybe ten years or more. On very rare occasions I will get a 'Trojan' that windows defender “real time protection” seems to detect.
This is what I currently have installed – too much – not enough, maybe:
Windows Defender with real time protection
Using Firefox, I have Adblock Plus, Ublock Origin and I just added BlockSite
Once a week I run the following 'anti' stuff in safe mode with networking:
Windows Defender – full scan
Hitman Pro
Adware Removal Tool by TSA
Adwcleaner
Bitdefender Adware Removal
Ccleaner
JRT
Rkill
Malwarebytes – install – run scan – uninstall with Revo
SuperAnti Spyware – install – run a scan – uninstall with Revo
Usually, when running these scans, 'rarely' is anything found, except some cookies or other minor stuff, never a virus or trojan.
So, two questions, can you have more than “one” real time protection for spyware, like having windows defender & Hitman Pro and or Bitdefender? I know your not supposed to have 'two' virus programs. Since windows defender and based on scan results, maybe its not necessary to have two real time protection, anyway. And or maybe it would slow down the internet.
And second, am I running too many scans in safe mode?
Thanks in advance for any suggestions
