Avast Cleanup - Getting Started

 

Avast Cleanup Premium is an optimization tool that scans your Windows device to identify unnecessary items and performance issues, freeing up disk space and improving the speed of your system.

This article assumes that the latest version of Avast Cleanup Premium is installed and activated on your Windows device. For detailed installation and activation instructions, refer to the following articles: Installing Avast Cleanup & Activating an Avast Cleanup Premium subscription.

Scan your Windows device

If you are using Avast Cleanup Premium for the first time, the application opens automatically after installation and you can click Scan now to perform a general scan.

The scan results are shown on the main dashboard. To perform subsequent general scans:

  1. Open Avast Cleanup Premium and click Rescan.
  2. When the scan is complete, follow the instructions for each found issue.

The general scan looks for junk items that can be cleaned and ways to improve system performance. For detailed instructions about each category, refer to the sections below.

Free up disk space

Avast Cleanup Premium scans for and safely deletes system junk and web browser data to free up disk space.

  1. Open Avast Cleanup Premium and hover your mouse over the side menu, then select Disk Cleaner.
  2. Select the category that you want to clean.
    If you have not ran a scan before, you are unable to choose a category or cleaning mode. In the top-right corner, click Scan system to run your first scan.
  3. Choose your preferred Cleaning mode.
    When you clean your browsers, if you select the Full mode, Browser Cleaner will delete the auto-fill data saved in your selected browsers.
  4. Click Clean.
    If you are cleaning your browsers and your browsers are open, close them, then click Continue.
  5. When cleaning is complete, click Back to Dashboard or Keep cleaning.

The selected file categories are now cleaned.

Enable Auto-Clean

Auto-Clean runs silently in the background with no actions required from you and frees up space on your Windows device by removing dispensable items, such as broken shortcuts and registry items.

To enable Auto-Clean:

  1. Open Avast Cleanup Premium and hover your mouse over the side menu, then click Settings (the gear icon).
  2. Select the Auto-Clean tab.
  3. Click the gray (OFF) slider so that it changes to green (ON).
  4. Optionally, use the drop-down menu to specify the frequency of scans.
  5. Optionally, select the file types that Avast Cleanup Premium has permission to remove during automatic cleaning. The file types that Avast ticks automatically are safe to clean without losing crucial data.

Auto-Clean is now enabled.

Manage applications

Avast Cleanup Premium scans your Windows device for outdated or unused applications, then allows you to easily update, sleep, or uninstall them. This helps ensure that your applications are running optimally and frees up resources on your Windows device.

Update applications

  1. Open Avast Cleanup Premium and hover your mouse over the side menu, then click App Manager.
  2. In the Updater tab, find the application you want to update, and click Update.
    If you have not ran a scan before, you are unable to choose the updater tab. In the top-right corner, click Scan programs to run your first scan.

The application is now updated.

To select when an application is updated, click Settings (the gear icon) in the Updater tab, then select Updater, and choose the update schedule.

Put applications to sleep

Certain applications slow down your system by running silently in the background. Avast Cleanup Premium scans for these applications, then allows you to safely put them to sleep and boost performance.

  1. Open Avast Cleanup Premium and hover your mouse over the side menu, then click App Manager.
  2. Select the Sleep Mode tab.
  3. The Sleep Mode screen shows applications that are running unnecessarily in the background and slowing down your Windows device. To put an application to sleep, click the green (ON) slider next to an application, so that it changes to gray (OFF).
If you use an application on a daily basis, we do not recommend putting it to sleep. Additionally, certain applications need to run in the background to offer full functionality. For example, if you put WhatsApp to sleep, you may miss incoming calls or messages.

The selected applications are now sleeping. You can open and use sleeping applications as normal. After you close the application, Avast Cleanup Premium automatically returns its status to sleeping.

To turn on a sleeping application, click the gray (OFF) slider next to an application, so that it changes to green (ON).

On devices with Windows 10 and higher, the Sleep Mode feature supports applications installed through the Microsoft Store. The relevant applications are installed in a Sleep state by default.

Uninstall unused applications

  1. Open Avast Cleanup Premium and hover your mouse over the side menu, then click App Manager.
  2. In the Uninstaller tab, find the application you want to uninstall, and click Uninstall.
  3. Select Uninstall to confirm the unistallation of the application.

The application is now uninstalled.

To change the duration after which programs should be categorized as unused, click Settings (the gear icon) in the Uninstaller tab, then select Uninstaller, and choose your preferred duration using the drop-down menu under Unused programs.

Analyze your Windows device

Open Avast Cleanup Premium, hover your mouse over the side menu, and click Disk Manager, to check for a variety of problems that may impact the performance and security of your Windows device. Follow the instructions on the Disk Manager screen, to resolve the problems.

For more information about the issues that Avast Cleanup Premium may detect during a Disk Manager scan, refer to the following article:

  • Avast Cleanup - FAQs

Recover your data

Data Recovery helps you to recover deleted files from hard drives and other storage devices. To recover files:

  1. Open Avast Cleanup Premium and hover your mouse over the side menu, then click Manage data.
  2. In the Data recovery tab, click Scan now.
  3. Select the relevant options in each category to narrow down your search. Click the drop-down arrow beside Show advanced filters to add extra filters on your search.
    Adding detailed filters can help you to find the desired items that you are looking for and help reduce the scan time.
  4. Click Scan.
    The scan may take several minutes to complete.
  5. Tick the boxes beside the files you want to recover, then click Recover.
  6. Select a folder you want the files to be recovered to, and click OK.
    We recommend choosing a different drive to increase your chances of successful data recovery. Data recovery to the same drive may end in the overwriting of recovered files and lead to the failure of the operation.
  7. Click Start recovery.
  8. When the files are recovered, click Back to Dashboard or Recover more.

  • Avast Cleanup - FAQs

Avast Cleanup for Android is a mobile app designed to help improve the performance of your device and preserve storage space by removing unnecessary media, files, apps, and app data. Remove these items by transferring them to a cloud storage account and/or deleting them from your device. You can also optimize photos to consume less space.

This article assumes that the latest version of Avast Cleanup is installed and activated on your Android device. For detailed instructions, refer to the following articles: Installing Avast Cleanup & Activating an Avast Cleanup Premium subscription.

Navigate Avast Cleanup

  1. On the Home screen of your device, tap the Cleanup icon to open the app.
  2. The following options are available via the main app screen:
    1. Quick Clean: Scan for and delete dispensable items, including thumbnails, APKs, residual files, and hidden, visible, and shared cache.
    2. Sleep Mode: Hibernate apps that are running in the background, stopping them from slowing down your device and draining your battery.
    3. Tips: Review tips for clearing space on your device. The first time you use the Tips feature, you are prompted to specify which kinds of tips you want Avast Cleanup to prioritize via the Analysis preferences screen.
    4. Media: Access an overview of the media that is stored on your device, including suggestions for clearing space.
    5. Apps: Access an overview of the apps that are installed on your device, including suggestions for clearing space.

Perform a Quick Clean

Quick Clean cleans your device by removing unnecessary files to free storage space. You can select which item types are removed before you clean.

  1. Tap the Quick Clean button.
  2. Tick the item types you want to clean. Item types are divided into two sections (you may see one or both sections, depending which data types are stored on your device):
    • Unneeded files: Data that has been carefully selected to ensure that it is truly dispensable, including thumbnails, APKS, residual files, and hidden, visible, and shared cache.
    • Files to review: Data that may not be valuable to you. We recommend reviewing items included in this group and only ticking items that are dispensable. All items are unticked by default and will not be deleted unless you manually select them.
  3. Tap Finish cleaning to delete the selected items.

Hibernate apps

The Sleep Mode feature stops apps from running in the background, releasing memory for other tasks.

  1. Tap the Sleep Mode tile.
  2. Tick the apps that you want to stop, then tap Force stop.
    You may need to grant Avast Cleanup permission to force stop apps in bulk via your device settings. Tap Grant, then follow the on-screen instructions. If you do not grant this permission, you are prompted to hibernate each selected app individually.
  3. Tap Proceed.
  4. Wait while Avast Cleanup hibernates the selected apps, then tap the back arrow to return to the main Avast Cleanup screen.

The selected apps are no longer running in the background.

Optimize your photos

Avast Cleanup allows you to optimize your images to occupy less space. Images that are already the same size as your device screen (for example, screenshots) are not optimizable. To optimize your photos:

  1. Tap ☰ Menu (the three lines) in the top-left corner of the main app screen.
  2. Go to Photo Optimizer ▸ Show photos.
  3. Photos are arranged in groups according to age. Tick the photo(s) you want to optimize, or tap Select all next to a group of photos to select the whole group.
  4. Tap the Confirm button at the bottom of the screen.
  5. Tap Continue to proceed with default optimization, or tap Setup to preview an optimized image. If you have a paid Avast Cleanup subscription, you can additionally set the optimization level according to your needs.
  6. Under Original photos, tap Select (or Change) to specify what will happen to your original photo(s). The following options are available:
    • Send originals to cloud storage: Remove the original photos from your device and send them to cloud storage. If Avast Cleanup is already connected to a cloud storage account, tap the email address connected to your preferred account. If not, tap Connect to cloud storage to connect the app to a new cloud storage account.
    • Just delete: Remove and permanently delete the original photos from your device.
    • Keep originals: Keep the original photos on your device.
  7. Tap Optimize now to immediately start optimizing the selected photo(s).
  8. When optimization is complete, tap the back arrow to return to the main Avast Cleanup screen.

Your photos are now optimized to occupy less space on your device.

Define your Analysis preferences

When you tap the Tips tile on the main app screen, you can review tips for clearing space on your device. You can specify which kinds of tips you want Avast Cleanup to prioritize via the Analysis preferences screen:

  1. Tap ☰ Menu (the three lines) in the top-left corner of the main app screen.
  2. Go to Settings ▸ Analysis preferences.
  3. Touch and hold the icon (four lines) next to a tip category and drag the panel up or down to reorder your preferences. Optionally, tap the slider beside Find unwanted photos to turn the feature on (blue) or off (gray).

Avast Cleanup shows tips according to your specified preferences.

Manage cloud transfers

'The cloud' refers to virtual storage space where you can keep media and files such as photos, videos, and documents. Avast Cleanup allows you to easily transfer items from your device to a connected cloud storage account. To connect Avast Cleanup to a cloud storage account:

  1. Tap ☰ Menu (the three lines) in the top-left corner of the main app screen.
  2. Go to Settings ▸ Cloud services.
  3. Tap Connect next to your chosen cloud service (Dropbox or Google Drive).
  4. Select your preferred account and tap OK. Enter login credentials if prompted.
  5. The account now appears under Connected. To sign out of an account, tap ⋮ More options (the three dots) next to the account and select Sign out.

You can be connected to multiple Google Drive accounts and one Dropbox account at the same time. If you are connected to multiple accounts simultaneously, you are prompted to choose an account each time you attempt to transfer data to cloud storage.
