Rather than a single utility, IObit Advanced SystemCare 15 is a toolkit made up of numerous components, and you can pick and choose which you want to use and when. With IObit Advanced SystemCare 14 you have everything you need to clean up, speed up and optimise your system as well as performing a whole range of important privacy and security-related tasks. Things might even slow down to the point that you think it's time to invest in a new computer – but this is probably not necessary. Without regular maintenance, your once fast PC is liable to grind to a crawl and become frustrating to use.
