I have an issue that under a certain combination of running programs, Malwarebytes kills my internet. This is on a new PC build. I never had this issue with my previous PC running the same combination of programs, but then, I built the new one because I hadn't been able to update windows 10 for over a year.
I run NordVPN, Malwarebytes Premium, windows antivirus, and a torrent client. IF I don't have Malwarebytes running, I can load NordVPN and the torrent client and close them as many times as I want, in any order. If I run Malwarebytes, I can connect and disconnect to the VPN as many times as I want, no issue. BUT, once I run the torrent client and exit it, if I try to run either the torrent client again or connect to the VPN, it kills my network adapter. At first this was via wifi, so I connected ethernet and disabled the wifi adapter. Same thing. I tied different torrent clients, some with no torrents even, same issue. I've updated all drivers that I can think of, scanned with multiple antivirus programs. I tried turning off all antivirus except Malwarebytes, same thing. I tried adding both the apps and the files and the folders for NordVPN and the torrent clients to the allow list, same thing.
When I say it kills my network adapter, it still shows it's there, doesn't say disconnected. But I can't disconnect it. The only way to get it working again is to restart. If I try to soft restart my PC, it just hangs, I have to hard restart.
