Avast Cleanup and windowsweep
Avast's paid PC cleaner, now part of the Avast One app, with junk removal, an app uninstaller, sleep mode for background programs and automatic maintenance.
01 / WHO IT SUITS
Which one suits you
Choose Avast Cleanup if you want bloatware detection backed by a cloud reputation system, an uninstall simulator and sleep mode for programs you keep.
Choose windowsweep if you want a free plan that runs every section rather than a 30-day trial, a command line with no run limit, and a dry-run before anything is removed.

“Not stated on the pages we checked” is not a no. The page did not say, so the question is still open, and Avast Cleanup's own site is where to ask it.
04 / THE OTHER SIDE
What windowsweep does not do
- windowsweep does not clear tracking cookies today. Cookies, logins, history and Local Storage are left alone in every browser profile, so a tool here that clears them does a job this one does not.
- The Free plan counts real runs: 15 a month on each machine, and 15 more once you sign in with Google. Dry-runs and scans are never counted, and neither is the command line.
- It has no undo. A cache it deletes is gone until the program rebuilds it. Only the sections that offer personal files and leftover folders use the Recycle Bin.
- It runs on Windows 10 (1809 and later) and Windows 11, and on nothing else.
