Issue
KCS / Tcoss cannot start anymore because the tcoss.exe was deleted by anti virus software.
Cause
Several different Anti-Virus packages started to delete TCOSS.exe since the weekend of 9/10th November 2019.
The following Virus scanners have been reported to delete TCOSS.exe:
- Trend Micro OfficeScan Agent
- Trend Micro Deep security
The result is that TCOSS/KCS is not running anymore / unable to start.
The KCS monitor shows "TCOSS unable to start process - Restarting" warning followed by a "TCOSS failed" error.
Solution
To restore TCOSS.exe and prevent deletion in the future, please white-list the following KCS folders:
- C:\MT
- C:\TOPCALL
- C:\TCOSS
Restore tcoss.exe afterwards from the Virus Scan quarantine.
If TCOSS,exe can't be restored, re-run the setup for "Make TCOSS" and copy the file from C:\MT\PRG to C:\TCOSS\SYSTEM.
Re-install any installed fixpacks.
If you've applied a fix that replaces tcoss.exe, apply it again.
