Undetected malware, please help.


Recommended Posts

While scanning my computer with Windows Defender, a prompt appeared, saying that "Preliminary Scan result show that malicious or potentially unwanted software might exist on your system. You can review detected items when the scan has completed." I have done multiple quick and full scans since last night, but Windows Defender reports that no threats were detected. This is on Windows 10 by the way. 

While looking up solutions, I found and followed the instructions on this thread: 

I followed steps 1 to 4, but Windows Defender is still coming up with that message. The first time I ran Malwarebytes, it quarantined 40 threats, and I cleaned them. The second time I ran it, nothing was found. Please help.

Hey Eagle, and thanks for responding. I have attached pictures of what happens during a quick scan with Windows Defender. In the results screen, it is also empty under the "Quarantined" and "Allowed" items sections. This would also have the same result during a full scan.

I forgot to mention in my first post, but yesterday some links I clicked would redirect me to a false error page I couldn't close, so I had to use Task Manager. Since following the steps from the other thread however, I have not been having links redirect me. I will post the rest of the logs that I got from running scans. One threat was found and removed using the Sophos Tool, but I don't remember what it was.

Hi Eagle, I have updated Windows Defender, but it still shows that message. I did a full scan with Malwarebytes after that, and it found 6 PUPs. I removed those, and did another quick scan, and the message appeared again. I'm not quite sure what to do anymore. I think this system might be infected, since I did the same scan on my laptop and the message did not appear. Any suggestions?

FRST.gif Fix with Farbar Recovery Scan Tool

icon_exclaim.gif This fix was created for this user for use on that particular machine. icon_exclaim.gif


icon_exclaim.gif Running it on another one may cause damage and render the system unstable. icon_exclaim.gif

Download attached fixlist.txt file and save it to the Desktop:

Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

  • Right-click on FRST.gif icon and select RunAsAdmin.jpg Run as Administrator to start the tool.
    (XP users click run after receipt of Windows Security Warning - Open File).
  • Press the Fix button just once and wait.
  • If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
  • When finished FRST will generate a log on the Desktop, called Fixlog.txt.

Please upload it to your reply.

I have done the fix and posted the log. Yesterday, I saw two pop-ups from Malwarebytes saying that a malicious website was blocked. I think it linked to Skype.exe, is there a way to pull up logs of the blocked website, and what should be done about this? I also did a quick scan right after it restarted, and the message still shows up.
