System Performance
If you need better system performance from your PC, Kaspersky has a wide variety of tools available, for instance, you can use Unused Data Cleaner, PC Cleaner, and Privacy Cleaner. It’ll assess both your local system and browser, ensuring that you don’t have unnecessary files or programs on either end.
Windows Defender also has some cleanup tools you can use, but they provide a basic service. Since there is no file shredding, it feels rather limited in functionality.
