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:
