However, Avast tools like Recuva, Speccy, and Defraggler are locked from use. For example, Windows 10 still allows users to install CCleaner, even if its listed as a PUA. If Microsoft is cautious of CCleaner, the company is outright dismissive of some other Avast tools. If a vulnerability occurs on the tool, Defender will not detect it. Specifically, CCleaner bundled with Avast antivirus could circumvent Microsoft Defender. Avast often bundles the tool in with its other security tools. An example of a potentially unwanted app is an application that has been bundled in with a program you may want to download.Īnd this is where Microsoft's stance on CCleaner rests. Baidu’s cloud clean technology can wipe junk files up to 2.5GB. PUAs are apps that have been uninstalled on a machine without the knowledge or consent of the user. Baidu Cleaner is a free software and a CCleaner alternative which employs an ultra-clean cloud technology to provide cleaning solutions for over 5000 programs and targets more than 10000 cleaning points. It automatically backs up the system before any cleaning is performed. When Windows 10 version 2004 arrive in May, Microsoft added protection against PUAs to Windows Defender (now Microsoft Defender). Wise Registry Cleaner is one of the safest Windows registry cleaners and registry defragmenters. It means an app is potentially unwanted but not necessarily dangerous or bad for the user. It is worth noting, the P in PUA is important. Developed by Avast, CCleaner itself is not a nefarious service, although the registry cleaner has been compromised by malware attacks in the past. Microsoft has never really liked registry cleaning tools. To protect Windows users, Microsoft Defender Antivirus detects CCleaner installers that exhibit this behavior as potentially unwanted applications (PUA)”. “Bundling of software, especially products from other providers, can result in unexpected software activity that can negatively impact the user experiences. Listed as “PUA: Win32/CCleaner”, Microsoft has finally decided to explain why it is listing the tool as a PUA: Microsoft Defender is now classifying the tool as a Potentially Unwanted Application (PUA). Redmond's concern was seemingly justified a month later when Avast confirmed a critical flaw in CCleaner. One project could have files scattered all over the filing cabinet – unless we take the time to pull out all of the files, put each project into one drawer so all of the files are together, and then go on.Back last year, Microsoft blacklisted the CCleaner tool from its Support Forum network, censoring mentions of the registry cleaning program. And if we still need more space, we’ll have another note in that drawer saying “Look into Drawer 2 for the rest of the files”. So we might put part of the files in one drawer, with a note to “See Drawer #3 for the rest of the files”. But suppose that a project takes up multiple files, and we don’t have space in one drawer for all of them. We open the file cabinet, find where we want to put our files, and put it away. Think of the computer as a big filing cabinet. Disk FragmentationĪnother issue of computer slowdown is disk fragmentation. And when that program is removed, the uninstall process might or might not remove its data – leaving bits and pieces of itself behind. Every time a program is installed, the registry grows. Windows operating systems use a database called the “Registry” that stores information on how programs on Windows work – where they’re installed, file settings, and a plethora of other settings. And just like clutter in the Real World, clutter is an issue in the world of computers. Reduce unneeded things, reduce the distractions, shrink things down to just what we need in life, and only keep things that give us joy. One of the goals of the Konmari movement is to reduce clutter in our life.
