Hi techenthu,
The solution is to basically recreate that file and put an exit script into it
Press the Windows Key + R to open the run dialog
Paste this command and click OK
shell:startup
Right click in that folder and choose New - Text Document
Put this text in that file:
Wscript.Quit
Then click File - Save As
At the bottom of the save as dialog, set save as type to *.*
Save the files as uB83ALflOKgnkFl.vbs
Note you must enter the vbs file extension yourself
Restart your PC
