S&D won't run/Safer-Networking.org offline?

[Warhammer: 3025]

Earlier today my Avira Antivir popped up that it had detected several trojans that had snuck their way onto my system. It subsequently quarantined and deleted the purported offenders, and now my system is behaving erratically. Windows Defender crashes upon attempting to read a specific .dll (which one I'm not sure), Spybot S&D will not run (though it will change the cursor to the "thinking" cursor for a short while on the attempt) and Safer-Networking.org comes up as being offline (though I can still access these forums, obviously).

If this is in the wrong forum, please feel free to move it.

Thanks in advance for any help you can provide.
