advanced system care is,in my opinion,crap and can do more harm than good,and yes,ive used it.optimizers are not needed or recommended and do nothing to "make your computer run faster".defrag your disk,and do a disk cleanup.the microsoft tools are plenty good for this.the only good thing iobit came out with was startmenu 8.
Ccleaner vs IOBit is only compared on a fair level if they are compared as registry cleaners or as uninstallers. As uninstallers, they also clean the registry of all left over traces of the program you are removing. If you aren't aware of IOBit's Uninstaller or if you want to try and call it crap, you are truly uninformed because it is probably the absolute best uninstaller on the market and best of all, the free version is more than most people need and few grades above what CCleaner has to offer
I am surprised your opinion of ASC is crap. But then again, opinions are like those things where crap comes from, everyone has one. Fact is, CCleaner is capable of several things ASC can do. But ASC is not crap and IOBit has many more great offerings than Start Menu 8
ASC is a Suite of utilities that exceeds what CCleaner is capable of and probably alot more powerful than anything else on the web with so many powerful features for absolutely no money. Since they make ASC nearly dummy proof to ensure it does what it's supposed to, doing more harm than good isn't really any way to describe what it is actually doing. It's more likely that using programs with terms like "Advanced" in the title might just be above your pay grade. Just sayin
