Bart uses Piriform CCleaner. Leo says that there's a new warning out to avoid CCleaner. Leo says that Microsoft Defender is flagging CCleaner has unwanted software because it includes other apps as part of the download. None of which Leo recommends. It's always best to avoid software that comes with a separate installer that ads other apps you don't want. CCleaner has addressed that issue to make sure it's no longer flagged.
Avast/Piriform has confirmed that its popular CCleaner app has been infected with malware for the last several months and that users who have used it may have had their computer's compromised. Avast says they believe that they've fixed the problem and that no users have been harmed by the hack. But Leo says he worries about the term "we believe," and this is yet another reason why using these kinds of apps to protect yourself gives you a false sense of security.
Mike got an error message that something had stopped working when he installed DropBox. He uninstalled it, but the error is still popping up. Leo says it sounds like the uninstall didn't get rid of all the necessary files and so the Windows registry keeps referring to them. He should go to DropBox and see if they have a removal tool. He can check his services in Task Manager too. That will tell him what it is and he can at least disable it.
Brett has a Dell computer and wants to know if there's an open source program that can speed up his computer like Dell does with Click to Fix? Leo says that Dell doesn't share their secrets and Leo doesn't think that it's safe to use a third party open source option for this. Dell's Click to Fix knows its own hardware and as such, can do a targeted fix. Open source stuff can't do that and can be overly aggressive and cause more problems than it fixes.
Rick wants to clean up his PC and make it run faster. Is there a piece of software that can do that? Leo says no. That's snake oil. He can run CCleaner and a registry cleaner, but that's risky as cleaning the registry can cause the OS to stop working. He can also optimize the disk, but that isn't necessary anymore since hard drives are very efficient these days.
