I couldn't agree more with Tomk...there is no reason to use these dangerous programs. Piriform and Iobit websites are cess pools of useless and unnecessary programs. Most folks have 1 Tb hard drives and use less than 100 gb so why bother and take the risks. ASC is dangerous bloatware. I run WOT (Web of Trust) on every browser as well as Adblock Plus and that keeps out most of the junk. You can delete your temp files all you want, that does nothing to your drive and they only build back anyway and will self empty when built up enough.
The word "optimize" is a trap for foolish users....everything you need is within Windows these days and if your pc slows down, look to your surfing habits and you will break your addiction on the dangerous products
