Hi,

I was looking through my startup and saw this entry:

13B60F.lnk C:\WINDOWS\system32\8C018A\13B60F.EXE

Does this look like some sort of malware?

I ran a few searches but couldn't find any information about the entry. When I locate and open the folder "*C018A" the contents are empty (even when I expose hidden files),. I can't find any trace of the executable: 13Bg0F.exe

Not sure if this is relevant, but there is also another folder "486C01" right below it and there is a *.txt file inside it.

Thank you for any info.

Usually if you cannot find any information on a file, its likely to be malware related but that's not always the case, especially since you are not reporting any symptoms of infection. It's also possible the file has already been removed and what you have is an associated reference (lnk file) to it in your startup. A lnk file is a shortcut which points to an .exe file located elsewhere on your system and can contain attributes to define how the program runs. Lnk files are primarily associated with the Windows operating system.

What does the text file in the other folder say when you open it?

Thank you for your reply!

when I open the text file in the other folder, it looks like a bunch of gibberish:

When you are unsure about a suspicious or unknown folder(s), you can rename them. If you receive an alert from Windows about renaming, just ignore it. I prefer renaming instead of deleting as deletion leaves you with no option to restore if the folder(s) are later found to be legitimate or needed. Taking no action exposes you to risk if it is not legitimate. After renaming both folders, move them to another location on your drive (i.e. C:\Hold) for a few days. If there are no adverse affects from taking such action, then you can delete them.

As a precaution, I would perform a full system scan with your anti-virus and an anti-malware program like Malwarebytes' Anti-Malware.

As for the startup entry, you can remove it. Please download AutoRuns and save it to your Desktop.
  • Create a new folder on your hard drive called AutoRuns (C:\AutoRuns) and extract (unzip) the file there. (click here if you're not sure how to do this. Vista users refer to these instructions.)
  • Open the folder and double-click on autoruns.exe to launch it.
  • Please be patient as it scans and populates the entries.
  • When done scanning, it will say Ready at the bottom.
  • Scroll through the list and look for a startup entry related to the file (13B60F) you need to remove.
  • Right-click on the entry and choose delete.
  • Reboot your computer when done.
If you're going to keep and use Autoruns, be sure to read:
