--- Original Subject ---
Mitigating false Behaviour Monitoring detection related to the Ransomware module of Trend Micro Worry-Free Business Security (WFBS

Bula Vinaka Sanjay

When the Ransomware module is enabled in WFBS, the Behaviour Monitoring falsely detects our Link Backoffice applications (i.e. linksoft.exe) as suspicious/malicious, and blocks it.

We have done some research and found that to solve the Behaviour Monitoring issue, the application can be submitted to Trend Micro support for verification and whitelisting. Once the application has been verified to be normal, it will be whitelisted to avoid further detection.

Link Technologies can apply for the Trend Micro GRID program where we can submit the application before public release. You may refer to The GRID: Goodware Resource and Information Database for more information - using the below link.

Hi Vineet, we will not be getting certification by Trend Micro as this is only one out of many antivirus companies that our clients may use. Instead, we are looking at digitally signing our install files. This will be implemented as part of the security enhancement programme we are undergoing at present.  The ETA will be provided once we have completed the current workset.
