This looks like a classic “partially removed” infection: startup/Winlogon entries are still pointing to randomly‑named DLLs that no longer exist, so Windows pops a RunDLL error at every boot. Immediate priorities are (1) stop further damage, (2) gather authoritative logs, then (3) remove the leftover startup entries rather than deleting random files by hand. (bleepingcomputer.com)

First actions (do these before experimenting with cleaners): disconnect the PC from the network, make a system restore point / registry export, and reboot into Safe Mode (or Safe Mode with Networking if you must download tools). Use Autoruns (Sysinternals) to inspect Run / RunOnce / Winlogon Notify / BHOs / services and uncheck or delete entries that reference missing or obviously random DLL names. Autoruns will “Jump to Entry” so you can see the exact registry location before removing it — export that key first. Autoruns (Sysinternals). (learn.microsoft.com)

Next, produce removal logs and run reputable scanners: run a full scan with Malwarebytes (or Malwarebytes Toolset if available) and the Microsoft Safety Scanner; also run Farbar Recovery Scan Tool (FRST) to produce FRST.txt and Addition.txt — those logs are what experienced responders need to advise precise removals. Do not rely on generic “registry boosters”; use the logs and post them if you want community help. Malwarebytes, Microsoft Safety Scanner. (malwarebytes.com)

After removal: check Winlogon/Userinit and remove any extra programs appended to it (restore the default userinit behavior per Microsoft guidance), then run System File Checker to repair any damaged system files:

sfc /scannow

Always keep a registry backup/restore point before edits. If infections persist or critical system entries are damaged, a clean OS reinstall may be the safest route. If can post the full FRST/Addition logs (and the OS version), responders can point to the exact registry keys and startup entries to remove. (learn.microsoft.com)

Hi and welcome to the Daniweb forums :).
