I decided to give the system cleaner a very limited try today. I don't usually use security suites, not to mention system cleaners, as I tend to be apprehensive about doing any widespread cleanup, especially with hard drives as large as they are today. That being said, I logged on to my administrator account to set up the cleaner to behave how I wanted it to. My WSA setup prevents non-administrators from making setting changes. Once it was setup how I wanted, which included unchecking firefox cache, windows temp, and system temp, as I definitely did not want to clean those, I logged back onto my standard user account to run the cleaner. As I watched it chug away, my jaw dropped and my blood pressure rose as I saw it cleaning stuff I told it not to. Then it hit me...was the system cleaner settings non-administrative? Does each user get to set their own preferences? I don't personally like that, as I don't want visitors using a standard account getting to pick what to delete on my computer. Nevertheless, I went into the cleanup settings, which were on defaults for my standard user, and attempted to change them to what I wanted. It wouldn't let me save them though, due to the non-administrative setting change restriction. So, something isn't working correctly here...the system cleaner appears to be something every user gets their own settings for, yet they can't change them if there is a setting restriction in place? That can't be working as intended. On a side but very important note: I use Firefox Sync to synchronize all my cookies, saved logins, passwords, history, etc. between my two main personal computers. By Webroot clearing out the "Mozilla Firefox - Cache", I am assuming that means just the cache, or data files. I hope Webroot did NOT delete any of my saved cookies, passwords, etc. Also, what is the possible risks of deleting windows/system temporary files? Some people do it regularly while my friend did it and somehow it caused an issue with World of Warcraft, so he claimed. This is the kind of cleanup I recommend not doing, and if it must be done, Windows has a tool for it. I'm afraid I'm just not a suite guy...I really like just the Antivirus version. Sorry to have something negative to say.
