Immediate Action

  • Update your Trend Micro products and pattern files to the latest version.
  • Scan the host exhibiting this type of network behavior to clean any detected items.

Secondary Action

If scanning fails to detect a malware infection:

  1. If possible, disconnect the host from the network to prevent any further communication or malicious activities the malware may attempt.
  2. Run RootkitBuster to check through hidden files, registry entries, processes, drivers, and hooked system services.
  3. Use the Anti-Threat Toolkit (ATTK) tools to collect undetected malware information.
  4. Identify and clean threats with Rescue Disk, specific to suspected threats that are persistent or difficult-to-clean. Rescue Disk allows you to use a CD, DVD, or USB drive to examine your computer without launching Microsoft Windows.
