Version 6.3 (6.2.0 Powertech Antivirus Unix/Linux Endpoints)

November 6, 2024

New Features

The Insite migration tools have been removed from the install package. They are now available from the Powertech Antivirus Server download page on the Fortra Support portal.
The install package is now self-contained and the need to download PostgreSQL and Java from the Fortra Support portal during installation has been removed. This also removes the need for air-gapped installation steps.
The PTAV Server now permits compatible endpoints (version 6.3.0 and above) to pass tags during the registration process. The tag names are case-insensitive and missing tags are created upon registration.
Scheduled scans and reports can now be targeted at a subset of endpoints based on individual endpoint tag names. You can preview the endpoints that the chosen filter (both endpoint names and tags) targets.
When attempting to set up an SMTP email connection, additional logging is enabled when the “Validate Email Connection” button is pressed. This will assist in diagnosing connection problems. The logging is directed into the file ptavws.log.
A new report type "Endpoint Status" has been added. This report can be tailored to include various fields representing the current state of an endpoint.
The reports table can be filtered based upon the type of report.

May 2023

Version 6.11 (6.2.0 Powertech Antivirus Unix/Linux Endpoints)

May 17, 2023

Enhancements

The PTAV scanners have been updated to use version 6600 of the Trellix (formerly McAfee) Anti-Malware engine. Changes include: scanning capability for the DEX file-type, new PDF 256-bit AES and RC4 40-bit encryption support, scanning capability for the APK file-type, extended AutoIT 2.x support, improved handling of manipulated MIME headers, improved DMG extraction support to include the APFS filesystem and UDRW format, expansion of hit-type limits to target more malware families, OpenSSL libraries are no longer used, multiple bug fixes and minor feature enhancements.
Endpoint installer packages now decompress DAT files during install/upgrade to improve scanner startup time. DAT updates pushed down from the PTAV web service also instruct this decompression. Product install requirements have been updated to recommend increased disk space for the decompression procedure.
On-access tracing state will now persist across service restarts.
The avupdate tool now has a decompress option to ensure DAT updates result in an optimized DAT set format that loads as fast as possible.
The sample script for notifications that is shipped with the product has been modified so that emails sent by using the script will use a formally correct example sender's address, powertech.antivirus_donotreply@yourorganization.com.
A log file (avscan.log) for the on-demand scanner (avscan) is now configured by default, and would include infected filenames. A new install would include this configuration, but upgrades might need some manual configuration changes to zlog.conf; see the README file in the endpoint installation for more information.
On endpoints running on AIX, when the sample script for notifications, notify-example.sh, was used, it sent email that included a blank instead of the system name in the subject line. This has been corrected. The subject line now does include the system name for notification emails sent from AIX systems through use of the new PTAV_HOSTNAME environment variable.

Updates

Endpoint disk space requirements have been increased to 2 GB disk space in /opt, 2.5 GB is recommended.
Endpoint installer metadata and tools have been rebranded to Fortra. An updated Fortra SLSA is included in the endpoint install.
