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:
- If possible, disconnect the host from the network to prevent any further communication or malicious activities the malware may attempt.
- Run RootkitBuster to check through hidden files, registry entries, processes, drivers, and hooked system services.
- Use the Anti-Threat Toolkit (ATTK) tools to collect undetected malware information.
- 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.
