Phew, I’m glad I’m not the only one!
Yesterday Avast stopped working – all modules disconnected (firewall/AV). I tried to repair the program, didn’t work. So I uninstalled and after restarting, Windows Defender said I had a trojan (Trojan:Win32/Codinx.B!cl).
Oddly, Malwarebytes never found this – so I’m not sure what’s going on.
I deleted the “trojan” and System Ninja and then ran a few more scans and reset all passwords just in case.
