The inclusion of "2021" suggests this file was active or created in that year. Pirated movie releases from specific years often circulate with embedded malware. Since Megamind was released in 2010, a "1080p" release labeled "2021" does not indicate a new movie release, but rather a re-encode or a re-upload (common in piracy scenes, but also common in malware re-distribution).
