3. AVG TuneUp

AVG TuneUp homepage.

AVG offers a free version but this only scans your PC. For actual tune-up, you’ll need to go for the paid version. This includes a performance optimizer that can greatly speed up your device. While it offers stellar performance, this is one of the priciest tools on the list.

The interface is beginner-friendly and this software works fast.

One of the neatest features of this tool is the live optimization. This lets you put certain programs to sleep on a priority basis, lowering the drain on your computer’s memory and CPU and speeding up your systems.

That said, there is a free seven-day trial which doesn’t require you to enter credit card details, so you can try before you buy.

Computer Tune-up FAQs

How often should I defragment my computer?

Generally speaking, we recommend that you defragment your hard drive once a month. Alternatively, you should defragment your drive when it has become 10% or more fragmented.

The good news is that Windows has a built-in defrag tool that you can use to keep your hard drive optimized. This ensures that you can keep your hard drive healthy without the need for any third-party tools.

If you want to defragment your hard drive (or check on its status), simply type "defrag" into the Windows search bar on the bottom left of your screen. Now, select the defrag window and choose Defragment and Optimize Drives.

Note that Windows 10 and 11 periodically defragment your drives by default, automatically.

What is a tune-up program?

Quite simply, a tune-up program is a piece of software that is designed to clean up your system, thereby improving its performance.

The best tune-up programs provide features such as disk defragmentation, browser extension management, benchmark testing, and automatic cleaning (removal of unwanted or unused files).
