Firefox, they are probably running CCleaner while Firefox is open. This is easy to correct...
Spybot & Ad-Aware cleaning features are less than clear, that's just bull@#$! right there.
#1. CCleaner's cleaning on them applications is just common cleaning standards.
#2. You can always open up any of the ini's and see what it cleans.
Uncheck all boxes under 'Applications'. That's just retarded, even a user with basic Windows knowledge could see none of the entries cleans "required" application files. Just common log, MRU's, and backups that are useless.
I have no reason to lie nor am I just saying this because I am a Moderator. I became a Moderator because I liked CCleaner and wanted to help anyway I can.
The only box you should uncheck is MS Office if you use it alot or have custom settings.
As for Issues, yes it does have it's corks. It sometimes does find registry keys that are vaild, just look over them. If you are unsure, just unselect it. You should always back up your registry before using any registry cleaning program anyways.
I just don't think they even took the time to actually see what it cleans nor do I think they even have any basic knowledge of the programs they use or Windows.
I will put it this way, you give me an application I have never used before and I will have CCleaner cleaning all traces of using that program (if possible).
They have no knowledge of Windows or the applications they use. They are entitled to their own opinion, as am I. But, I love the way people say CCleaner crashed or messed up my system, or something along them lines. They never have any details on what caused it, (if it even was CCleaner). We have not received any posts saying any of the problems stated on they are saying.
There are some really smart pc techs on this forum that use this program for work related and never has it caused any of the problems stated.
Do as you wish.....
