If you have an old computer or you use your computer quite a bit and it’s getting a bit slow, perhaps you should consider downloading a cleaner and get that “new computer feel”.
Piriform have a product called CCleaner which will clean and optimize your machine. The CCleaner will clean temp files, cookies and your history among other things. The very basic version is free so why not? You can upgrade to the professional or business edition for a fee if you love it. In addition to the CCleaner, you can use their defrag product, Defraggler, to optimise and sort out your hard disks. The CCleaner will work on both Windows and Mac but the other products are only available for Windows.
