They get a message saying the that “ibbackuplib.dll” is missing or quarantined. In both instances McAfee was deleting the file or tagging it as a threat. To correct this, find the quarantined zone and restore the file.
To avoid it from happening, add the file to the “exclude file” list.
Here is where you locate the exclusion list in McAfee. In the sample screen shot below I added Interbase just in case.
Click on add file and you browse for that specific file.
