Windows Defender in safe mode??

[jholland1964]

(a file called itpb_4.exe existed, but I guess that's OK - not removed)

DANG!
Left out a KEY line in my post to you;

Navigate to;
C:\WINDOWS\itpb_4.exe[876056.exe]
C:\WINDOWS\itpb_6.exe[whCC-MTHREE.exe][whInstaller.exe]
C:\WINDOWS\itpb_6.exe[whCC-MTHREE.exe][webhdll.dll]
C:\WINDOWS\itpb_6.exe[whCC-MTHREE.exe][whiehlpr.dll]

Forgot to say DELETE if found! But you obviously understood.
Rats!

The file noted in you post was that in C:\Program Files\? of where I have noted above?
Give me a few minutes to run through your logs and I will be back. Go back and get rid of that file though, Don't reboot either yet.
