The only times I have ever received it on my PC is through adware bundled through installers, accidentally... And that particular installer never mentioned anything about it (no boxes to untick/options) (adware), so... Yeah. Kind of funny how a Security companies' product is bundled in a installer, appearing like adware considering I had no option but oh well... You can try Glarysoft Utilities, I found it better for a beginner with cleaning products (especially registry cleaning) to get started with it. Only use Advanced Systemcare if you know what you are doing with your registry etc because it is very easy to mess up and have something go wrong with the registry cleaner, and that never happened with CCleaner or Glarysoft. Only advanced systemcare I have been told about the issues, and myself as a user of ASC I have had that issue occured (long time ago when I first used it of course
). Personally, I think ASC is better but then again, if you don't want to end up accidentally messing anything take the safer route.
