How can I prevent KIS from destroying a specific file attached to email?

Recommended Posts

KIS destroys a file when I send it to myself as an email attachment. It is a file that I wrote myself and it does not contain threats, as verified when I test it with KIS.

With KIS protection off, I try to send the file to myself from OneDrive with MS Outlook -- sending to an address that is an alias of my Gmail address. The email never shows up in the Gmail inbox whether KIS protection is on or off.

The email with attached file remains in the Sent mail folder of Outlook. It stays in the Sent folder of Outlook until I turn KIS protection back on and select it. Then KIS destroys the attachment. On the other hand, the file is not destroyedwhen I select the email in Outlook's Sent mail as long as I keep KIS off.

The nature of the file is this:
I have a folder containing two other folders each containing a zipped .EXE file+some other files. The top folder is also zipped - making it all one zipped file of 7 MB .

I have tried changing names of the two inner *.exe files to *.txt but results are the same.

KIS version (g)

Windows 10 version 10.0.19043 build 19043

Outlook Version 2016

Hello @stanhilliard

Welcome back!

  1. Which Mail Anti-Virus settings are configured? 
  2. When KIS “destroys” the file, is it being assigned to KIS Quarantine? 
  3. Has a case been logged with Kaspersky Support

Please let us know? 

Thank you🙏


Here is an additional note on my purpose:

I usually transfer this type of file by putting it in OneDrive an sending a unique link to the person only. One company doesn’t allow downloads from OneDrive through their network.

I have made one successful email attachment transmission. But I want to be able to send to myself as verification that the system is working.

So I  am willing to temporarily change KIS protections just during that operation - and then probably change them back after saving the attachment to my HD. 

Here are my Mail Antivirus Settings.

  1. Log a case with Kaspersky consumer support, either via Chat or Email, select Application malfunction, Other template. Support may request logs, traces & other data, they will guide you.

I found another solution - so I will post it here.

There were actually two things interfering with sending the file as an attachment.

1 My antivirus, Kaspersky Internet Security (KIS) did not accept that type of file. So in KIS settings I uncheck "Scan Attached Archive". (After sending I turn it back on.)

2 The Gmail system blocks and destroys my file (a zipped file containing .exe’s) when I send it or receive it there. So I created an alias to the Gmail address. An email sent out from Outlook and the alias will bypass the Gmail account and thus its ability to disable the attached file.

My configuration is this:
I have the Gmail operating in Firefox. I set up the alias address as an account in Outlook and Mail and sent the attached file from there. (Both Outlook and Mail worked equally well.)

My procedure is to
1) Turn off antivirus scanning of the attached archive.
2) From the alias, send the email with attached file.
3) Turn on antivirus.

Other things to Expect:
1 - The inbox of the alias will always be empty -- as any email addressed to the alias will be forwarded to the Gmail inbox.
2 - The sent folder of  the alias will retain a copy of the email/file.
3 - If I select the sent email/file after turning the antivirus back on KIS will quarantine it. So I lose the use of the Sent folder, but that is OK because there is a copy of the file remaining in my OneDrive.
