Those .dat files are malware related.RunDLL32.exe
is a legit Windows file that loads .dll files which too can be legit or malware related. The Cannot find or error loading
error message usually occurs when the associated .dll has been removed. The file may have been removed during an anti-virus scan, the uninstall of a program or use of a specialized fix tool. However, an associated registry entry remains and is telling Windows to load the file when you boot up.
If the file was removed but not the entry, Windows will display an error message indicating that the file was not found or there was an error loading. You need to remove this registry entry so Windows stops searching for the program when it loads.
To resolve this download and run Autoruns
, search for the related entry and then delete it.
- Create a new folder on your hard drive called AutoRuns and extract (unzip) the file there. (click here if your not sure how to do this.)
- 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 with the error message.
- Right-click on the file and choose delete.
- Reboot your computer and see if the startup error returns.
