Avast Cleanup Premium 21.4 Build 11223 Updated -

Avast Cleanup Premium 21.4 Build 11223 was a significant update released in late 2021. This version introduced several user-requested features and performance optimizations designed to streamline PC maintenance. Key Features in Build 21.4.11223

Faster Junk Cleaning: The Disk Cleaner scan was optimized to be up to 50% faster than previous versions.

Flexible Browser History: A new setting allows users to retain cookies and browser history for up to 30 days before they are automatically cleared.

Streamlined Menu: The main menu was revamped to provide direct access to all Avast subscriptions, allowing users to manage accounts and settings from one central location.

Website Exclusion: Users can now exclude specific websites from the Browser Cleaner, enabling them to stay logged into frequently used sites while still cleaning other data. Core Functionality

This build continues to offer the core suite of Avast Cleanup Premium tools:

Sleep Mode: Optimizes startup items and puts background apps to "sleep" to free up resources for current tasks. Avast Cleanup Premium 21.4 Build 11223

Disk Defragmenter: Helps prevent system crashes and freezing by optimizing hard drive storage.

Automatic Maintenance: Regularly fixes broken registry items and shortcuts without requiring manual intervention.

Bloatware Removal: Identifies and removes unwanted pre-installed apps and toolbars. Installation & Availability Free Trial PC Cleaner | Avast Cleanup

Final Verdict: A Mature, Trustworthy Optimizer

Avast Cleanup Premium 21.4 Build 11223 is not a revolutionary product, but it is an exceptionally polished one. It successfully automates the boring, repetitive tasks of PC maintenance—cleaning temp files, updating software, disabling bloatware, and hibernating runaway processes—while keeping safety rails firmly in place.

The build’s improvements over earlier versions (better browser cleaning, improved sleep mode reliability, and fewer false positives) show that Avast is listening to user feedback. It does not promise to turn a 10-year-old Pentium into a gaming rig, but it will make that same Pentium boot faster, run cooler, and crash less often.

For the average user, the $39.99 annual subscription is justifiable if you value time and convenience over manual tinkering. For power users, it’s a convenient backup tool for cleaning client PCs or family machines. Avast Cleanup Premium 21

Rating: 4.2 / 5
Deducted 0.8 for the persistent upsells and background resource usage.

Last tested: November 2021 on Windows 10 21H2 and Windows 11 RTM. Avast Cleanup Premium 21.4 Build 11223 remains stable and effective as of this write-up, though newer builds (22.x and 23.x) have since introduced additional features like disk defragmentation and driver updater.

4. Browser Cleaner

Modern PCs suffer from digital "dust" inside web browsers. This build deep-cleans Chrome, Firefox, Edge (Chromium), and Opera. It removes:

  • Stored download histories (saving disk space)
  • Old cache files that clash with new website protocols
  • Unused browser extensions that track background activity
  • Cookies older than a user-defined threshold

Crucially, Build 11223 introduced selective cleaning, allowing users to keep passwords and auto-fill data while purging everything else.

6. Registry Cleaner & Defragmenter

The registry cleaner in Build 11223 is conservative—it only removes keys that are clearly orphaned (e.g., references to uninstalled software). It includes a full backup and restore point creation before any changes, a critical safety net that newer versions have buried behind menus.

Avast Cleanup Premium 21.4 Build 11223: The Ultimate PC Optimization Guide

In the ever-evolving landscape of digital maintenance, keeping a Windows PC running like new is a constant battle. Over time, systems become clogged with junk files, broken shortcuts, outdated software, and background bloatware that slows down boot times and application performance. Enter Avast Cleanup Premium 21.4 Build 11223—a specific, robust version of Avast’s flagship optimization suite that has garnered attention for its stability and feature set. Last tested: November 2021 on Windows 10 21H2

This article provides an in-depth review, feature breakdown, performance analysis, and download guide for Avast Cleanup Premium version 21.4.11223.

1. One-Click Maintenance (The "Health Check")

The centerpiece of Build 11223 is the revamped Health Check. In one click, the software scans four critical areas:

  • Junk Files: Temporary files, cache, recycle bin debris, and old Windows update leftovers.
  • Performance Issues: Visual effects that slow rendering, power settings that throttle performance, and startup cascade delays.
  • Broken Shortcuts: Dead links in the Start Menu and desktop that waste indexing time.
  • Registry Errors: Invalid ActiveX entries, missing DLL references, and obsolete software paths.

User Interface Walkthrough

Build 11223 sports the iconic Avast purple-and-white color scheme, but with a cleaner layout than previous versions. Upon launching the application, the user is greeted with a dashboard showing a circular "Performance Score" from 0 to 100%.

The left sidebar contains four primary sections:

  • Health Check: The one-button solution.
  • Speed: Contains Sleep Mode, Startup Manager, and Browser Cleaner.
  • Clean: Houses the Disk Cleaner, Shortcut Cleaner, and Registry Cleaner.
  • Troubleshoot: A tool for fixing common Windows errors (blue screens, missing DLLs, broken context menu entries).

The Settings menu (gear icon) is where Build 11223 shines. Users can exclude specific folders from cleaning (e.g., a video editing cache), set file age limits (e.g., "only delete temporary files older than 7 days"), and enable "Silent Mode" to suppress all popups.

✅ Buy it if:

  • You run Windows 10 on an old mechanical hard drive.
  • You want a one-time purchase (some licenses still sold for this version) rather than a subscription.
  • You need a standalone optimizer without cloud-based analytics.
