This old RAR archive containing a UPX-packed gaming keyboard driver shows zero detections across 64 engines including top tier-1 scanners.
0251c1869dafc59c86…07ff6b77c8The 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.
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.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.
