Anti-Virus File Exceptions for Tricerat Products

When you deploy Tricerat products, your anti-virus software may flag certain ScrewDrivers files as suspicious--particularly the virtual printer drivers and low-level system integration components. This is normal behavior since these files hook into Windows printing and scanning subsystems.

You'll need to add these files as exceptions in your anti-virus configuration to prevent false positives and ensure ScrewDrivers operates correctly. Here's the complete list of files that commonly trigger anti-virus alerts:

Virtual Printer Driver Files​

These are the core ScrewDrivers virtual printer driver components located in the Windows print spooler directory:

  • C:\Windows\System32\Spool\Drivers\x64\ScrewDriversDrv.dll
  • C:\Windows\System32\Spool\Drivers\x64\ScrewDriversUI.dll

Protocol and Integration Support Files​

These files handle protocol integration (ICA, RDP, TCP/IP), database connectivity, and PDF functionality:

  • C:\Windows\System32\dnssd_md.dll
  • C:\Windows\System32\sdpDBH.dll
  • C:\Windows\System32\sdpDBSQ.dll
  • C:\Windows\System32\sdpGW.dll
  • C:\Windows\System32\sdpICA6.dll
  • C:\Windows\System32\sdpPDF.dll
  • C:\Windows\System32\sdpRDP5.dll
  • C:\Windows\System32\sdprovider.dll
  • C:\Windows\System32\sdpTCP.dll
  • C:\Windows\System32\sqlapiu.dll
  • C:\Windows\System32\TriceratMessage.dll

Scanning Components (TWAIN)​

These files provide scanning functionality through the TWAIN interface:

  • C:\Windows\System32\TWAINDSM.dll
  • C:\Windows\System\TWAINDSM.dll
  • C:\Windows\twain_32\scanect\FreeImage.dll
  • C:\Windows\twain_32\scanect\ScanectFT32.ds
  • C:\Windows\twain_32\scanect\ScanectFT32UI.ds
  • C:\Windows\twain_64\scanect\FreeImagex64.dll
  • C:\Windows\twain_64\scanect\ScanectFT64.ds
  • C:\Windows\twain_64\scanect\ScanectFT64UI.ds

Installation Directory Files​

Beyond the files listed above, all other Tricerat program files are installed under C:\Program Files\Tricerat. You may want to add this entire folder as an exception in your anti-virus configuration for comprehensive coverage.
