Avast Cleanup Premium: Does It Actually Speed Up PCs?

Avast Cleanup Premium is a paid utility that automates junk-file removal, startup-program management, and background-app suspension to free up storage and memory. It can make an older PC feel more responsive by clearing clutter and stopping resource-hungry processes, but it does not boost raw processing power or fix hardware limitations. Here is what the software actually does, how it works, and whether the speed gains are worth the subscription.

What Avast Cleanup Premium Includes

Avast Cleanup Premium is a separate product from Avast’s free antivirus, though it is often bundled in Avast One or sold as a standalone subscription. Its core features are:

• Junk-file cleaner – removes temporary files, browser caches, leftover installer files, and old logs.
• Startup manager – disables or delays programs that launch automatically when Windows starts.
• Sleep mode – suspends background apps that are eating memory or CPU, then wakes them when you use them again.
• Browser cleaner – clears browsing history, cookies, and cached data from Chrome, Firefox, Edge, and others.
• Duplicate finder – scans for duplicate photos, documents, and other files to reclaim disk space.
• Software updater – flags outdated programs that may have security holes or performance issues.

Unlike a full antivirus suite, Cleanup Premium does not scan for malware or offer real-time protection. It is purely a maintenance tool.

How It Speeds Up a PC (and How It Doesn’t)

The speed gains from Avast Cleanup Premium come from two main mechanisms: freeing up disk space and reducing background load. When your hard drive is nearly full, Windows can struggle to write temporary files, and the page file (virtual memory) has less room to expand. Clearing gigabytes of junk can help, especially on older HDDs. Similarly, if your PC has only 4–8 GB of RAM, suspending background apps can prevent constant swapping to disk, which makes everything feel snappier.

However, the software cannot make a CPU faster, add more RAM, or upgrade a spinning hard drive to an SSD. If your PC is slow because the processor is old or the hard drive is failing, Cleanup Premium will not fix that. It also does not defragment drives, clean the Windows Registry in any meaningful way, or optimize network settings—despite what some marketing implies.

What the “Speed Up� Claims Really Mean

Avast’s own marketing says Cleanup Premium can “speed up your PCâ€� by removing junk and managing startup items. In practice, the most noticeable improvements happen on machines that are heavily cluttered or have limited RAM. A benchmark test by independent reviewers (like those on YouTube or tech blogs) typically shows boot-time reductions of 10–30 seconds and lower RAM usage after sleeping background apps. But on a modern PC with an SSD, 16 GB of RAM, and a clean system, the difference is often imperceptible.

One common misconception is that cleaning the registry speeds up a PC. Avast Cleanup Premium does not include a registry cleaner—and that is a good thing, because registry cleaning can actually cause problems. The software focuses on safe, reversible actions like deleting temporary files and disabling startup entries.

How It Compares to Windows Built-in Tools

Windows 10 and 11 already include several free tools that do much of what Avast Cleanup Premium offers:

• Storage Sense – automatically deletes temporary files and empties the recycle bin.
• Disk Cleanup – removes old Windows updates and system files.
• Task Manager – lets you disable startup programs manually.
• Settings > Apps – uninstall unused software.

The advantage of Avast Cleanup Premium is convenience: it bundles these tasks into one interface, automates them on a schedule, and adds features like duplicate file detection and app sleeping. The disadvantage is the cost—and the fact that it runs in the background itself, using some resources.

Common Problems and Criticisms

Users have reported several issues with Avast Cleanup Premium:

• Aggressive upsells – the installer often pushes other Avast products, and the free trial auto-renews if you don’t cancel.
• False positives – the duplicate finder may flag files that are intentionally duplicated (like backup copies), and the browser cleaner can log you out of websites by deleting cookies.
• Sleep mode glitches – some apps, like messaging clients or download managers, may not wake up properly, causing missed notifications or stalled downloads.
• Resource usage – the software itself can use 100–300 MB of RAM, which is noticeable on low-end machines.

There have also been privacy concerns about Avast’s data collection practices in the past (the company sold user data through a subsidiary, Jumpshot, which was shut down in 2020). While the current privacy policy is more transparent, it still collects usage data by default.

Is It Worth the Price?

Avast Cleanup Premium typically costs around $40–$60 per year for one PC, though discounts are common. Whether it is worth it depends on your situation:

• Worth it if: your PC is several years old, has a small SSD or HDD that is often full, and you are not comfortable using Windows built-in tools.
• Not worth it if: you have a modern PC with an SSD and 8+ GB of RAM, or you are willing to spend 30 minutes manually cleaning with free tools.

Before buying, try the free trial and see if you notice a difference. Also check if your Avast antivirus subscription already includes Cleanup Premium—it is often bundled with Avast One or Avast Ultimate.

Alternatives to Avast Cleanup Premium

If you want similar functionality without the subscription, consider these free options:

• BleachBit – open-source junk cleaner for Windows and Linux.
• CCleaner – has a free version, though it now includes ads and bloatware.
• Windows Storage Sense – built-in, automatic, and safe.
• Autoruns (from Sysinternals) – advanced startup manager for power users.

For duplicate files, you can use free tools like Duplicate Cleaner Free or AllDup. For background app management, Windows 11 has a built-in “Energy saver� feature that limits background activity.

Frequently Asked Questions

Does Avast Cleanup Premium actually make games run faster?

It can help if your game is stuttering because of low disk space or background apps eating RAM. By clearing junk and sleeping background processes, you free up memory for the game. However, it won’t increase FPS if your graphics card or CPU is the bottleneck. For most gaming PCs, closing a few programs manually is just as effective.

Is Avast Cleanup Premium safe to use?

Yes, it is generally safe, but it can cause issues if you let it delete files you need. The browser cleaner may log you out of websites, and the duplicate finder could delete a file you wanted to keep. Always review the list of files before confirming deletion. Also, be aware that Avast has had privacy controversies, so consider disabling data-sharing settings.

Can I use Avast Cleanup Premium with another antivirus?

Yes, Cleanup Premium is a separate tool and can run alongside other antivirus programs. However, if you use Avast’s free antivirus, the Cleanup Premium subscription often integrates with it. Running two full antivirus suites is not recommended, but a cleaner plus a different antivirus is fine.

How long does the free trial last?

Avast Cleanup Premium offers a 30-day free trial, after which you are charged for the subscription unless you cancel. The trial requires a credit card or PayPal account. Some promotions offer a 7-day trial instead. Always cancel before the trial ends if you don’t want to pay.

Does Avast Cleanup Premium slow down my PC while it runs?

The software runs in the background and uses some RAM and CPU, but the impact is usually minimal on modern PCs. During a scan, it can use more resources, which might cause a temporary slowdown. You can schedule scans for times when you are not using the computer.

Will it uninstall bloatware?

Avast Cleanup Premium does not have a dedicated bloatware remover. It can uninstall programs you choose, but it won’t automatically detect and remove pre-installed manufacturer bloatware. For that, you would need a tool like BCUninstaller or manually uninstall from Settings.
