6 days ago - CCleaner Professional gives you extra features and the best value for optimizing your computer. CCleaner Professional includes the. The CCleaner video tutorial uses CCleaner Professional: a version of CCleaner that is virtually identical to the free version of CCleaner, but includes one year of support and updates.
CCleaner Professional Plus will keep your computer running smoothly.
Is your computer running slower than it used to? This happens to everyone. No computer runs as fast as it did on day one until you completely reinstall Windows on it.
This is what most people believe to be the solution. Some people never think twice and format their PC to get the speedy performance. But not everyone can do so.
Some of us have only one computer, with a single partition on the hard drive. So, all your data is on the one partition. You can’t take a backup of your data. And wiping the disk will erase all of your content, are you prepared for this? No, no one ever is.
But there are ways to fix a slow computer, with some regular maintenance. Not by cleaning the hardware, but the hard drive’s content and the operating system itself.

A full hard drive can be a real headache. I recently fixed a computer which was running painfully slow, due to the C: partition on it was almost full. Luckily there were two larger partitions with free space, so I just resized the partitions to extend the C: drive and hey presto, it worked.
But sometimes you just can’t fix it like that and have to manually free up the hard drive space. For this, the basic steps are cleaning up the Windows temporary files, and browser’s data, etc. You can try uninstalling programs or games or large files (movies) etc. The problem is that it requires a lot of manual effort, and hence you may not have time for all this.
This is the reason, I recommend using Piriform CCleaner Professional Plus. The premium version has quite a bit of extra features which make it worth the money.
Let’s take a look at the program. The Professional Plus has a clean interface which comprises of three sections. There are two sidebars on the left and a large pane on the right-hand side. Selections you make on the sidebar are reflected on the right pane.
The first sidebar has the following options:
- Cleaner
- Registry
- Tools
- Options
- Cleaner
The Cleaner has two tabs: Windows and Applications. The Windows section lets you clean all the junk files from temporary internet files, browsing history and cookies etc in Internet Explorer, thumbnails cache, recent documents and other content from Windows Explorer, System data like those stored in Windows Temp folder, Recycle bin,clipboard, etc., and some advanced options.
Now, these aren’t the only programs which you use right? What about the other browsers and applications which also have their own data is for, and lets you clear data stored by Mozilla Firefox, Google Chrome, etc, and also applications like WinZip, Adobe Photoshop, PDF reader programs, Steam, Download Managers, Windows Media Player,etc.
These options are very important, and you should run the cleaning tool to keep your personal browsing history, banking, shopping info, etc safe from spyware, or hackers. Once you run the analyze tool, it will list the data which will be deleted from each program, and let you decide to clean the data (delete the files) or not. You can uncheck the data which you wish to retain, by unchecking the option next to its name in the sidebar.
Registry
One of Piriform CCleaner Professional Plus’ most powerful features, is the Registry Cleaner, it comes with. This lets the program scan for and delete useless or empty items from the Windows Registry. This includes Missing Shared DLLs, Unused File Extensions, ActiveX and Class Issues, Type Libraries, Applications, Fonts, Application Paths, Help Files, Installer, Obsolete Software, Run At Startup, Start Menu Ordering, MUI Cache, Sound Events and Windows Services.
Once the scan is completed, you can go through the list and unselect items to be deleted, and then click on fix issues. Now, CCleaner will prompt you with an option to backup the registry. Do so, it only takes a few KB. Doing so will let you restore the registry in case of issues you may run into. Then you can safely hit the fix button to delete the unwanted registry items.
Tools:
This option consists of 7 tools.
Uninstall – This tab lists all of your installed programs and lets you uninstall or repair them.
Startup – This tab shows you which apps run, when your computer boots. It also lists scheduled tasks which are run during start-up, and also allows you to manage which options appear in the context menu (right-click menu in Windows Explorer)
Browser Plugins – This option allows you to see which add-ons or extensions you have installed in browsers like Internet Explorer, Mozilla Firefox, Google Chrome, etc. You can disable or enable or delete the add-ons directly from this tab.
Disk Analyzer – A very useful tool which lets you analyze the hard drive to see which files are eating up the storage space. You can filter it to scan for pictures, music, documents, video, compressed files, email or everything on the HDD. You can also choose to scan only particular drives if you have more than one connected to the PC.
Duplicate Finder – Similar to the Disk Analyzer, but this tool scans your drive for duplicate files which can be deleted. It can match files by name, size, modified date, content, and ignore some pre-selected criteria (can be configured).
System Restore – Though it is Windows’ safety net, should a disaster occur, it consumes a lot of storage. These are usually created when you install or uninstall programs, and can be deleted safely over time. The most recent restore point will not be deleted.
Drive Wiper – This option can be used for deleting an entire hard drive, or to overwrite free space. This helps in preventing file recovery to protect your privacy. You can select a simple overwrite which uses 1 pass, or multiple ones of 3, 7 and 35 passes.
Options:
You can manage the various settings of CCleaner Professional Plus from this section. This includes options for premium features like the automatic cleaner which regularly deletes junk files to optimize your computer’s performance and also protects your privacy by deleting the browsing history and cookies when your web browser is closed. Don’t worry about losing your account logins, because CCleaner has an Intelligent Cookie option, which can be used to whitelist the account information on useful sites (like Google, Facebook, Twitter, etc).
You can also use it for including/excluding files or folders from the cleaning tool.
The Professional Plus version also allows Ccleaner to keep itself automatically updated to the latest version. The real-time monitoring option in the Professional Plus version can prompt you to run the cleaner when a selected storage space can be saved on the hard drive.
I always carry CCleaner around on my flash drive along with a portable anti-virus, when someone asks me to help them with their slow computer. In fact, it is one of the programs which I download first on a new computer, after a security suite and a modern browser.
In addition to a computer which is optimized automatically, with real-time monitoring, scheduled cleanings, auto updates, you also get access to Piriform’s Premium Support with Professional Plus.

CCleaner (/ˈsiːkliːnər/, originally Crap Cleaner),[6] developed by Piriform, a company acquired by Avast in 2017, is a computer utility program used to clean potentially unwanted files (including temporary internet files, where malicious programs and code tend to reside) and invalid Windows Registry entries from a computer, originally supporting Microsoft Windows only.[7] It is one of the longest-established system cleaners, first launched in 2004.[8]
CCleaner has been reviewed by Chip.de,[9]TechRadar,[10]PC Magazine,[11] and TechRepublic.[12]Both an installable and a portable version are available.

Features[edit]
CCleaner can delete temporary or potentially unwanted files left by certain programs, including Microsoft Edge, Internet Explorer, Firefox, Google Chrome, Opera, Safari, Windows Media Player, eMule, Google Toolbar, Netscape, Microsoft Office, Nero, Adobe Acrobat, McAfee, Adobe Flash Player, Sun Java, WinRAR, WinAce, WinZip and GIMP[13] along with browsing history, cookies, recycle bin, memory dumps, file fragments, log files, system caches, application data, autocomplete form history, and various other data.[14] The program includes a registry cleaner to locate and correct problems in the Windows registry, such as missing references to shared DLLs, unused registration entries for file extensions, and missing references to application paths.[13] CCleaner v2.27 and later can wipe the MFT free space of a drive, or the entire drive.
CCleaner can uninstall programs or modify the list of programs that execute on startup.[15] Since v2.19 CCleaner can delete Windows System Restore points.[16][17]
A version for Mac OS X was introduced and was at v1.15 as of October 2018.[18] A commercial Network Edition was also introduced. Piriform released CCleaner for Android in 2014.[19]
Critical reception[edit]
CNET editors gave the application a rating of 5/5 stars, calling it a 'must-have tool'. It was awarded Editor's Choice Award in April 2009 by CNET.[20] In 2016 Piriform announced 2 billion CCleaner downloads worldwide [21]In January 2014 it had been the most popular software on FileHippo for more than a year, and had a 5-star editor's rating on Softpedia.[22] CCleaner has been reviewed by Chip.de,[9]TechRadar,[23]PC Magazine[24] and TechRepublic.[25]
Security issues[edit]
Trojan in distributed program[edit]
![How to open ccleaner How to open ccleaner](/uploads/1/2/5/8/125849204/529591174.jpg)
After Piriform was acquired by Avast, in September 2017 CCleaner v5.33 (32-bit Windows) was compromised by the incorporation into the distributed program of the Floxif trojanmalware that could install a backdoor, enabling remote access to 2.27 million[26] infected machines.[27][28] Forty of the infected machines received a second-stage payload that appears to have targeted technology companies Samsung, Sony, Asus, Intel, VMWare, O2, Singtel, Gauselmann, Dyn, Chunghwa and Fujitsu.[29][30] On 13 September, Piriform released CCleaner 5.34 and CCleaner Cloud 1.07.3191, without the malicious code.[31] On July 24, 2018, the US National Counterintelligence and Security Center (NCSC) released a report titled 'Foreign Economic Espionage in Cyberspace' in which it reported a link between China and the Floxif backdoor used to target US companies.[30]
Data harvesting[edit]
Ccleaner v5.45 introduced 'features aimed at providing [Piriform] with better aggregated, anonymous usage data that we can use to spot trends to improve our software, fix bugs more quickly and deliver a better user experience', adding 'CCleaner does not report any personally identifiable information'.[32] After criticism[33] later versions allowed reporting of anonymous usage data to be controlled separately by the user.[34]
Installing bundled software without user permission[edit]
In December 2018, it was reported that users installing CCleaner would also have Avast antivirus installed without their permission, with TechSpot claiming this arguably made CCleaner no better than the malware it was supposed to defend against, but this was denied by CCleaner staff.[35] On the 20th of January users on Reddit posted screenshots that illustrated the issue had not been resolved, contrary to claims by CCleaner staff.[36]
