I faced the same problem yesterday morning. Yes it is happened after AVAST update in morning.
Since - the file already deleted, you cannot recreate it. After long trying, discussed with my manager, then we un installed the developer suite, reboot the system then install the developer suite. It works for me yesterday.
Oracle Developer Suite 10 G -(Forms [32 Bit] Version 10.1.2.0.2 )
You also need to copy APPSTAND.FMB & TEmplate.FMB to your local folder where form is mapped to avoid error -FRM-18108 -Failed to load Objects..
Try this if still you have problem, let me know. If you solve with other work around, let us know as well.
Dear CDigitalDeveloper ,
I've faced the same problem and i solved it by restoring the file from Avast's "Virus Chest" folder , it's where Avast moves the files detected during scanning. If you didn't find it there, you can copy it from another machine which has the same version of Developer Suite installed on it, or you look for the file in the installation CDs.
In addition to that, I have excluded this path (DevSuiteHome_1\BIN) from Avast's "File System Shield" service, so that it will skip scanning this particular folder in future. Because this service is a real-time scanner that monitors the files and programs all the time.
I think that the permanent solution for this problem is communicating with Avast support team to flag this file as a harmless file.
If you need any help, please feel free to contact me.
