in short it says I had same problem after a Friday morning program update and restart the laptop after that.
I didn't notice that Friday that there were no updates anymore, I noticed it first on Monday where program stayed orange and last update of Friday morning
no automatic update and also no update by hand.
even with firewall stopped still the same
I removed EIS, also with some problems. used the Emsisoft cleaner.exe
after removal restarted the laptop, installed the fresh downloaded EIS again and after that automatic update functioned again
pç/laptop here who updated the latest EIS on Saturday and Monday were not infected
hope it helps you
