Firstly, i didn't say "it finds more so it must be better", so that's not my logic. Also i don't use the deep scan feature. But i still don't find the registry scan (without deep scan) aggressive. And user has a chance to look at them before fixing them. If i'm caring about what i'm doing, then i'm fine, and i said i didn't had any troubles so far. Furthermore it solves some problems. Should this comment make you fit me into sth? anyway
If you don't use "Care" button, you can see what will be done to your system before the fixing process. For instance, for system optimization part: Just go to "Diagnose System" page, press "Scan". Then you may see something like "x problems found" in system optimization part. Click on it and you'll exactly see what will happen to your system.
I don't see any bugs or errors in the program, just works smoothly (version 3.3.4). Maybe in the previous versions you had some bugs, as i didn't use it for some time.
Btw, today i was getting "no disk" error and it fixed it fortunately. Actually the system optimization works well and fixes many problems (it also helped me a few times in the past).
Here i don't aim to discuss on which is better or sth else. You just criticized the program like it is so bad and does cause lots of dangerous cases. And then saying that it has restrictions in the free version, then "TuneUp probably being the best and safest one to use" (which has no free version) lol. You criticized the program without knowing some parts of it, I found your criticisms unfair, you compared it with other products, all these stuffs make you seem like you are just bashing the program. That's why i mentioned TuneUp a few times and made such a comment.
