Malwarebytes Premium 4.5.31 – Stable, Lightweight Protection for Windows

Malwarebytes Premium 4.5.31 is a refined 4.x build that focuses on smoother performance and a cleaner experience for Windows users who want extra protection alongside or instead of a traditional antivirus. This version keeps the familiar interface but runs lighter in the background, so scans, real‑time blocking, and updates have less impact on everyday use, even on mid‑range PCs.

In this release, Malwarebytes improved overall performance, reworked its notification system, and adjusted how trial messages are shown, so users see fewer, better‑timed pop‑ups. It also fixed an annoying issue where a Windows update could stop Chrome from launching, along with several smaller bugs, which makes 4.5.31 noticeably more stable than earlier 4.x builds.

Backed by strong test scores in independent labs, Malwarebytes Premium 4.5 still offers solid protection against zero‑day malware, ransomware, and malicious websites on Windows 10 and Windows 11, with very few false positives. If you need a “set and forget” security layer that stays out of your way but reacts fast when something dangerous appears, Malwarebytes Premium 4.5.31 remains a very good choice in 2026.
