Slim Cleaner Plus is a PC optimization tool which is supposedly capable of improving the performance of the user’s computer and making the battery life of laptops last longer by getting rid of redundant data, registry keys and software. However, a number of cyber security researchers as well as quite a lot of users have reported that this piece of software is actually a PUP – a potentially unwanted program. In the following lines, we will go over the different factors that make this piece of software potentially unwanted and so that you can decide for yourself whether or not you want it on your PC. In case you have Slim Cleaner Plus on your machine and you are having difficulties removing it, know that we can help you uninstall this program with our guide which you can find below this article. However, our advice for you is to first get to know this program better by reading the remainder of this write-up an only then try completing the guide manual. That way, you will have a better understanding of what you are actually dealing with and you will also have easier time avoiding such apps in the future.

The functionality of system optimization tool

Naturally, everybody wants their machine to run faster and smoother and their batteries to last longer and there are indeed hundreds of software tools out there that seem to offer exactly that. However, as is with most things, not every program that is promoted as super useful, helpful and effective is necessarily that way in reality. This might be the case with Slim Cleaner Plus as well. Now, we must say that we aren’t saying that this app is useless and that it is incapable of helping in any way. However, there things that suggest that its supposed functionality is significantly exaggerated by its creators. Normally, apps like this one are promoted as being able to greatly improve the speed and the overall performance of one’s computer. One of the main ways such programs are supposed to achieve that is by cleaning the Registry Editor. This practice, however, is oftentimes regarded as dubious. First of all, there is no conclusive proof that cleaning a computer’s Registry off redundant entries would offer a significant (if any) improvement to the computer’s performance. Secondly, a lot of specialists actually warn that allowing some obscure app to tinker with your PC’s Registry keys can actually do more harm than good. If the incorrect key is deleted or modified, there are a number of issues that can occur so bear that in mind. There’s actually a official statement by Microsoft, where they state that they do not support or approve of the use of such optimization tools as in many cases such software might actually worsen things.

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

If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!

Intrusive promotion

Another particularly unpleasant trait of programs like Slim Cleaner Plus is the way they try to push their paid versions. You see, most users typically initially only get the free versions of such apps and in most cases the free version only offers a scanner that can help detect issues on the PC. This can actually be useful as it could show you where the problem is and you can then go fix it manually. However, there are reports that suggest Slim Cleaner Plus actually tends to give false positives – it might detect a certain piece of software or some other data on the machine and mark it as problematic whereas in reality there’s no actual issue with the detected component. This is all a sneaky method of promoting the paid version of the optimizer – once an issue is detected (regardless of whether there’s an actual problem or it’s a false positive), the app prompts the user to buy the full version in order to resolve the problem. Many users actually fall for that and purchase the license for the optimizer even in cases where they might not really need it. Obviously, this is a rather dubious practice and now, that you are aware of it, you should probably think twice the next time some obscure optimization program prompts you to buy its license as a way to fix some problem on your machine that might no even be there.

Avoiding PUPs

Most PUPs are distributed through file-bundling so be careful when you want to install something new on your PC. Always check the Custom setup menu to see if there is anything added as optional install. If you find any bundled data, uncheck the entries that seem sketchy. Now, Slim Cleaner Plus has an official site from where it can be downloaded but it’s still not impossible to land this app through a file bundle if you aren’t careful.
