Run Windows Defender Offline now. You have malware.

Windows Defender Offline, WDO link in my signature. Please use that link only.

You will find instructions there. We also have a tutorial on using. Here is the procedure that i use:

HOW TO USE WINDOWS DEFENDER OFFLINE ON A USB STICK
Windows Defender Offline
is a free standalone, bootable malware and virus remover from Microsoft.
performs an offline scan of an infected PC to remove viruses, rootkits and other advanced malware.

Download Windows Defender Offline (about 764 kB)

You will have the choice of downloading the 32bit version (x86) or the 64 bit version (x64).
The link will help you determine whether you are running a 32 bit version or 64 bit version of Windows

NOTE!! You can download and prepare a 32 bit version using a 64 bit version of Windows
NOTE!! You can download and prepare a 64 bit version using a 32bit version of Windows.

You run the 32 bit version on a 32 bit version of Windows.
You run the 64 bit version on a 64 bit version of Windows.

The 32 bit download file name is: mssstool32.exe
The 64 bit download file name is: mssstool64.exe

For the curious, this program was originally name Microsoft Standalone System Sweeper.


INSTALLATION:
You will need an Internet Connection.
Insert 512 mB (Microsoft’s 256 mB is no longer accurate) or larger USB stick into a usb port.
Run the downloaded program--mssstool64.exe or mssstool32.exe
NEXT button
Choose the option On a USB flash drive that is not password protected
NEXT button
NEXT button
.
The install program will format the usb stick using the NTFS format.
The install program will download about 210 mB.
The install program will name the USB stick WDO_Media32 or WDO_Media64
The WDO_Media32 usb stick will have used space of 255 mB (268,140,544 bytes)
The WDO_Media64 usb stick will have used space of 282 mB (296,165,376 bytes)
You can expect the number of mB to increase as more malware appears.

UPDATE Windows Defender Offline USB stick:
reinsert the usb stick
run the installation program, mssstool64.exe or mssstool32.exe, again.
the update will download about 66 mB (mssstool32.exe) and 68 mB (mssstool64.exe).

Since the malware database is sometimes updated several times in a day, always update before running.

PERFORM AN OFFLINE SCAN
Bootup your computer from the USB stick
Windows Defender Offline will automatically perform a quick scan.
After the quick scan finishes, Choose Full Scan
Select all of your drives

The initial, full scan can easily take several hours, but
Remember, your computer is being very thoroughly checked for all types of malware.


RESULTS OF THE SCAN
The results will be in:
\Windows\Windows Defender Offline\Support,
file name format is MPLOG- as one or more files with a TXT extension which can be viewed with Notepad.

Ran Custom scan but nothing found in report screen...?

There's no "\Windows\Windows Defender Offline\Support"

If nothing is found in a WDO scan...is no log created ?

Thanks...Tim

MS has moved things again.
I'll get the correct location for you.

However, if after running a FULL scan of all drives. then you are ok. The History tab will show you what was found during the scan.

Found the logs...they are in C:\Windows\Microsoft Antimalware\Support

I have multiple drives on my system and selected all of them for scanning...But the scan did not run for hours and hours...maybe between 1 & 2 hours at best.

Also the logs do have some "warnings"...I have combined the 4 logs into one text file attached.

Anything strange in this report...?...And can you tell if indeed all drives were scanned ?

Thanks so much....Trinaz

trinaz,
Thanks.

Those warnings can be ignored.

they've been there since day one and MS has never fixed that. Those warnings should be ignored by us and removed by MS.

Followup on the ZZZ.ZZ.ZZ files in my original post jpg's. These files are apparently created when using CCleaner and the "Wipe" free space option. It appears CCleaner is supposed to delete them upon conclusion of a "wipe" session...but in my case (and in others) it didn't. It must have deleted them when they disappeared after a subsequent normal CCleaner operation minus the wipe option in setup ?

Anyway...for anyone that comes across this issue...just Goggle CCleaner, wipe and ZZ.ZZ.ZZ etc, and there's a number of posts on this...
