For : the symptom (rundll32.exe error at shutdown) plus the HijackThis details point to a startup/Run entry that invokes rundll32 to execute something staged in a temporary location — a behavior often used by malware to persist or execute payloads. (research.splunk.com)

Practical cleanup workflow (follow in order; make a full backup or create a restore point first):

  1. Boot Safe Mode (prevents many malware self‑protection tricks).
  2. Download and run an on‑demand scanner (Malwarebytes is good for this class of infection) and Microsoft’s Safety Scanner; update definitions before scanning.
  3. Use Sysinternals Autoruns to locate the offending startup entry (Logon, Scheduled Tasks, Run/RunOnce locations). Disable (uncheck) first; delete only after confirming the image path points into a Temp folder and not System32.
  4. If an executable/DLL in Temp is referenced, upload its hash or the file to VirusTotal before deleting (avoid uploading sensitive personal files).
  5. Reboot normally and re-scan. If cleanup succeeded, run SFC to repair/verify system files. (bleepingcomputer.com)

Cautions and verification: confirm the real rundll32 runs from the Windows system folder (not from Temp or user folders) before removing anything; deleting the wrong system DLL or EXE can break Windows. If the malware appears persistent (recreates entries, rootkit signs), collect logs and escalate to experts rather than doing ad‑hoc edits. (learn.microsoft.com)

asked for the Read Me First logs — a fresh Autoruns export (Logon + Scheduled Tasks), the full on‑demand scan reports, and a FRST/OTL or DDS log will let responders confirm removal and advise final cleanup steps.
