Cleaning Avast Secure Browser (ASB)

For CCleaner to clean Avast Secure Browser, the application can utilise the command line arguments (CLAs) made available in the custom build of the browser. When calling AvastBrowser.exe, use the CLAs to run cleaning commands (provided by browser extension APIs under the hood) to report results into a file with JSON format.

Here are the API reference details:

--clean-browsing-data=(required, non-empty) - a comma separated list of data types to clean. Possible values are:

  • appcache
  • cache
  • cacheStorage
  • cookies
  • downloads
  • fileSystems
  • formData
  • history
  • indexedDB
  • localStorage
  • serverBoundCertificates
  • pluginData
  • passwords
  • serviceWorkers
  • webSQL

--clean-browsing-data-origin=(optional) - a comma separated list of origin types to clean.

Possible values are:

  • unprotectedWeb
  • protectedWeb
  • extension

--clean-browsing-data-timerange=[start]-[end](optional) specifies the timestamps to clean between. This timestamp is formatted as the number of milliseconds since the Unix epoch. If [end] is missed then it removes until "now".

--clean-browsing-data-report=(optional) - path of the file to write the cleaning report data to. The format is a dictionary with data types that were requested to be cleaned. Each data type has a count (i.e. total number of entries) and an entries array of objects. Inside the entries array, there is path and size information. The path may be a URL or some other identifier (e.g. profile:guid for form data). The size information is represented in bytes and is non-zero only for some data types (e.g. cache).

Sample command: AvastBrowser.exe --clean-browsing-data=cache,cookies,formData,history,passwords --clean-browsing-data-report=C:\ccleaner-report.json

Important Note: for more information about cleaning categories and origin types supported by the Avast Secure Browser, please visit the Chrome Browsing Data developer reference page here.

Reporting Results

To report the browser cleaning results back to CCleaner, you can pass a JSON dictionary as follows:

Sample command: CCleaner.exe /report "report-ccleaner-sample.json"

Connecting CCleaner & ASB

The provided sample registry key file will enable the browser to load CCleaner and pass cleaning report data back to it. You can verify this by visiting the browser's Security & Privacy Center page and observing that the 'Privacy Cleaner' tile has updated to 'CCleaner'.
