The verdict, reasoned out.

Not a rules engine. The MT AI Engine reads every signal we collected, weighs them against history, and commits to an answer.

96%Confidence
Very high
Reasoning

Zero malicious or suspicious detections from 64 reporting engines, including strong tier-1 consensus on clean (Avast, BitDefender, ESET, Kaspersky, Microsoft). The file's age (over 10 years) and medium prevalence (28 submissions) without issues point to legitimate commodity software. Unsigned RAR with UPX PE is common for drivers but raises no flags here given universal clean scans and no triggered heuristics or external intel. Lack of runtime data is noted but outweighed by static evidence.

Files are processed in a streaming pass-through — MalwareTips never stores the binary on its servers. Only the scan result (hash, detections, verdict) is retained so the next person who scans the same file gets an instant answer. If you ran this file on your computer and are worried, scan your system with an up-to-date antivirus and change critical passwords from a different device.
