MSME 8.6 problem with .rar attachments

[pcmcis]

Hi,

Since 11/02/2019, MSME 8.6 is blocking all .rar attachments. I have no problem with .zip files.
Detected Items > Unwanted 
Triggered scanner / filters = packers

I am sure I didn’t change anything in the master policy.

Did something change in the last 2 .dat updates?

Hi , 

The issue seems to be with the latest DAT  for AV. 

You can contact the TAC team to get an extra DAT if every RAR files are blocking as a packer and if it is only for rar5. you can exclude rar5 in packer module or contact the TAC for an extra DAT for the same

Hi,

The DAT version 9166 resolved the issue.

Hi,

Yes, the problem is resolved and we are able to send .rar attachments again.

Now I have a new problem removing the exclusion and will create a new post.

Thank you for your help,
