This page aims to help you remove CCleaner Malware Virus. Our removal instructions work for every version of Windows.

We all know what CCleaner is – a legitimate program that is widely popular and used (I use it too). This is not an article about it. This is an article about how to deal with the CCleaner 5.33 malware that has been reported to be contained in said version of the software. In the event that you have it on your computer and are worried about the safety of your system – you really should be. CCleaner Malware is what’s known as a Trojan horse virus and this is easily among the most dangerous and notorious malware types out there. Allowing this Trojan to remain in your system any longer than it already has is inevitably putting both the system and yourself at risk. Therefore, it’s important that you know how to precisely locate the virus and remove it from your computer as soon as possible. For this purpose we have designed a detailed removal guide, which you can find below the following article. The process will require all of your computing skills and your utmost attention, so be sure to take this very seriously. If for whatever reason you don’t feel confident enough to be dealing with a virus like this, you can always rely on our professional removal tool, as well, which will have the task completed for you within minutes. But before you proceed to either removal option, please read the following few paragraphs so you know exactly what you’re facing.

What is CCleaner 5.33 Malware? How did I get infected?

There are numerous ways in which you could have landed an infection with this or any other Trojan. And what’s disappointing is that most distribution methods for this and other malware types rely on people neglecting basic safety measures. Trust us when we say that a very large portion of infections can very easily have been avoided should the victims thought twice about their actions and simply have applied their common sense. For example, to this day one of the most common spreading techniques for Trojans, ransomware and other viruses is spam emails. If you recall receiving an email from an unfamiliar sender with an attachment or link in it, asking you to open that file or link, it’s very likely that CCleaner Malware may have been embedded there and you yourself let it into your system. You could have also gotten it as a drive-by download from some shady or illegal website. Viruses like this are often also distributed via downloadable content, such as Trojans, shareware, etc.

But what can CCleaner Virus really do to your system that makes this such a feared threat? Well, there are perhaps even more possibilities here than there are infection methods. For one, the hackers may be after valuable data, so the Trojan could be planted as a thief. With its help, the criminals behind it could gain access to very sensitive information via your keystrokes, traffic hijacking and even screen-sharing. This could even include data like your credit or debit card details, passwords, login credentials on various websites, etc. Another very common usage of Trojans and other viruses is spying. Using the above and other techniques, you could watched, eavesdropped on and tracked. It’s not uncommon for criminals to use this sort of thing for the purpose of getting to know your whereabouts at home, for example. That way they can instigate a robbery and know exactly what to go for, when and how.

Some of the steps will likely require you to exit the page. Bookmark it for later reference.

Reboot in Safe Mode (use this guide if you don’t know how to do it).



We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

Drag and Drop Files Here to Scan
Maximum file size: 128MB.

This scanner is free and will always remain free for our website's users. You can find its full-page version at:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


Hold together the Start Key and R. Type appwiz.cpl –> OK.


You are now in the Control Panel. Look for suspicious entries. Uninstall it/them. If you see a screen like this when you click Uninstall, choose NO:



Type msconfig in the search field and hit enter. A window will pop-up:


Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.

  • Remember this step – if you have reason to believe a bigger threat (like ransomware) is on your PC, check everything here.

Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.


To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.

Type Regedit in the windows search field and press Enter.

Once inside, press CTRL and F together and type the virus’s Name. Right click and delete any entries you find with a similar name. If they don’t show up this way, go manually to these directories and delete/uninstall them:

  • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious.
    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

Other possibilities include involving your computer in botnets. This could be done for the purpose of sending out spam, infecting other computers within the same network with Trojans, etc. Alternatively, Trojans like CCleaner Malware can also be used as backdoors for other types of malware, including ransomware. Not to mention that a virus of this type can simply be used for purely destructive purposes, laying waste to your entire system or carefully picking out certain files that it wants to delete. As you can see, this is no joking matter and the sooner you get rid of CCleaner Malware – the better.

And once you have, you can take some precautions to ensure that you don’t land infections like this again. You can do so by installing the latest updates for your system, as well as updating your security software or installing one, if you don’t have one already. Very often outdated software or an outdated OS forms a vulnerability, which a Trojan can use to infiltrate your computer. In addition, think of the most common distribution techniques we described earlier in this article and your best to try and steer clear of those potential malware sources.
