Title: Boot Scan
Post by: AvastUser015 on December 04, 2013, 09:13:37 PM: I just did a Boot Scan for the first time and discovered these errors.

File C:\Windows\System32\DriverStore\FileRepository\prncacla.inf_amd64_9b92c72816d21e9\Amd64\CNBJ2530.DPB|>_5_Kolt50vpJyqlets20vm3zt2n4b Error 0xC000009C {STATUS_DEVICE_DATA_ERROR}

What do these messages mean? Are they serious? I am running the latest version of Avast with latest defs. I am running Windows 8 Pro 64 bit.
I am thinking that it has to do with 64 bit system and Avast is 32 bit. Also, I am using TrueCrypt on system partition, but it asks for my TC password before Avast starts scanning. Thanks.

Btw, no infections were found.

Post by: AvastUser015 on December 05, 2013, 03:38:16 AM: Problem Solved...I ran Error Checking (Windows) on the drive and it showed errors. It ask me to restart to fix the errors. I then ran Error Checking again it said no errors were found. I then ran Avast Boot Scan and this time no errors and no infections. Thanks for all your help. I wish programs could provide a more user-friendly error message and solution.

Post by: igor on December 05, 2013, 11:09:41 AM: Well, it would be nice (to have "clear" error messages), but unfortunately it's not that easy.
The program asks the operating system "get me the data from this file" - normally, everything goes well and the operating system says back "No problem, here you are". But sometimes the operation fails - and the system says "Reading failed with error 123456". There are hundreds of error codes, thousands of places where those errors may occur... and the reason is not always clear.
Preparing a program for every possible problem (software, hardware, filesystem etc.) with a specific message isn't really possible.
