Hi DaFit
Can you please check the logfile from C:\ProgramData\F-Secure ? Logfile.log can show a similar log entry:
'example.xls' matches 'Disallowed Inbound Files' stripping condition; Real type: application/vnd.ms-excel; description: Microsoft Compound Document;Microsoft Excel Document; VBA;doc_long: Microsoft Excel 2003 Worksheet;doc_class: Biff8;doc_spec: Excel.Sheet.8;appname: Microsoft Excel; extensions: XLS XLA VBAThis means that the file has been blocked since it is either a XLS or XLA file, or it includes VBA macros.
You can try to change the settings for policy Disallowed Inbound Files by removing the VBA from the list, and see if that improve the situation.

I dont want VBA but i want to receive XLS.

Hi DaFit
Do you have ESS Standard or Premium installed ?
We have a hotfix to exclude VBA autorun.macro which I can send you the download link for.

Dear Jamesch,

Could we receive the hotfix? We had a support case (xxxxxx) with a local customer which may have been related to the same problem.
Thanks in advance, Yours Sincerely:

Hi DaFit
I would suggest you to disable Email Traffic Scanning > Incoming Email > "Intelligent file type recognition", and let me know if the .XLS file is still being blocked.

Please check your inbox. I have just messaged you the links for the hotfix

Dear jamesch,
after disabling the "Intelligent file type recognition" the xls work.would this hotfix also work for that?

This particular hotfix provides exclusions for the following infections:
Trojan-Downloader:W32/Kavala.W
Trojan:W97M/AutorunMacro.B
Your case seems to be because of this: Real type: application/vnd.ms-excel

Hi DaFit
I have receive a response from the relevant team and they advised, currently no.
Are you certain that there are no scripts inside the XLS file ?0 -
Dear jamesch,
yes, there is no Script.
If i save it as XLSM or XLSX the file will work.

Thank you for the file. I will get it checked out, and update you as soon as I have some results. But do note, there is no ETA.

Hi DaFit
Thank you for your patience. We have an update on your issue and will let you know once we have developed a fix.
We have checked your XLS file and ran a few tests. It seems sometimes Excel saves common XSLX files as XLS with _VBA_PROJECT_CUR inside.
So, our products strips your XLS because there is that _VBA_PROJECT_CUR folder, even if there are no actual macros is inside.9 -
Dear jamesch,
Thank you for information.
I will point this out to the sender.
Best regards0 -
Hi DaFit
You are welcome.
Could you ask customer if disabling "Intelligent file type recognition" is a suitable workaround or can they wait until ESS 14 ?0 -
Dear jamesch,
we dont change the settings and release the message if needed.
When will ESS 14 be available?
best regards

Hello,
we have this same exact problem. Did I understand correctly that this is fixed in ESS 14 RTM? We still use ESS 12.12 and I would like to fix it even before upgrading to 14. Is it possible to get the hotfix?

We have this issue as well with 12.12 and are running Exchange 2010 which is not supported by version 14. Should we submit a ticket to get the hotfix?

Hi all
We have the fix ready, for ESS 12.X on Exchange Server 2013 (and later), where it strips XLS files (not Autorun macro) even with exclusion.
Please let me know if you want the fix
