Sorry for the replying delay, I had to go to work.

Woah. After I removed the lzx32.sys with rustbfix.exe then ran combofix.exe, the suspicious inbound connections decreased in amount. And there were no suspicious outbound connections anymore. My internet connection felt A LOT lighter than before.
I’m doing scans with avast & AVG-AS, I’ll post the results here later.

And… uh… I closed my combofix log accidentally after I read it and now I can’t find it anywhere. Does anyone know where the log is located? I checked C:\Combofix but the log was not there. I’ll run combofix.exe again if necessary.
