We are pleased to present version 2.0 of the Attachment Checker for JIRA plugin.
New Features for Attachment Checker 2.0
Support scanning of attachments for viruses
This addresses the feature request raised in https://jira.atlassian.com/browse/JRA-8626 (Virus Scan Attachment)
It also solves the performance issue listed in Anti-virus in jira applications where Jira users experience slowness due to scanning of temporary files.
When an attachment is added, a request is sent to scan the uploaded file. The request is handled asynchronously so that users need not wait for the scanning to completed especially if the file is large.
When a file is suspected to be infected, it will post a comment to the issue in the format "Filename" - "Alert Message". 
The user will receive a Jira email notification of the comment to follow up.
Please refer to Additional steps for anti-virus scanning for detailed instructions.
Checking for attachments with duplicate filenames
The Attachment Checker will alert the user that there is already another attachment with the same filename. The user can then determine someone has already uploaded the file or to rename the filename and upload again.
Improvement in the UI
The configuration settings are now grouped by their feature to make it more user-friendly for the users
