Can’t Remove Cache Killer Chrome Malware? This page includes detailed instructions to remove Cache Killer Chrome Malware at the bottom half of the article.

Cache Killer Extension Chrome Malware is a potentially unwanted program (PUP) that shares similar characteristics with other programs of the Browser Hijacker category. Therefore, we considered to be a Browser Hijacker. Some of the most notable traits of this type of software is its ability to introduce changes to the user’s browsers (Chrome, Opera, IE, Firefox, etc.) without the user’s permission as well as to generate unwanted advertising materials (pop-ups, banners, page redirects). Potential browser changes that can be caused by a Hijacker program are replacement of the starting page or of the search engine as well as installation of a new toolbar that gets added to the browser. Even though most of what was mentioned above does not pose direct security threat to your PC, it is still rather unpleasant to have this done to your browser, especially if you haven’t agreed to it. Therefore, we believe that it is usually better to get rid of any Hijacker programs that might have gotten installed on your computer. With this in mind, we have created a removal guide for Cache Killer Chrome that you can find down below and use it in case you have had the PUP installed onto your machine.

A profitable business

Online marketing is clearly a very common way for developers to earn income. Internet ads are becoming more and more common. Browser Hijackers take all this to the next level – instead of having ads implemented within the code of a website, with Hijackers, the advertising materials get generated onto the computer. However, unlike Adware, Hijacker programs can also be used for a number of other tasks to further boost the potential profit that can be gained. As we already mentioned, those applications also tend to alter various browser and internet settings on your PC – this also serves the purposes of web advertising and gaining money through online marketing.

On the other hand, the regular customer hardly ever benefits from programs of the Browser Hijacker category. There might be some functions offered by Hijackers but oftentimes their actual use is way too limited to make it worth keeping such a software on your PC especially when taking into consideration the unwanted changes to the browser and the potential ads and page redirects. In addition, there could even be certain security risks that come from Hijackers – we will go over this in one of the next paragraphs.

In terms of what this particular Browser Hijacker supposedly to the customer when it comes to functionality, it basically serves as a browser extension that clears the browser’s cache before a page is loaded. On paper, this could actually be kind of useful – it can improve the loading times of pages and save the user’s bandwith. It even ads an easily-accessible toggle button to the top-right of your browser’s toolbar.

 Additionally, the program also offers a quick way to delete your browsing history for separate sites with the click of one button. 

 However, once you take into consideration the negative effects that come from this program, it becomes apparent that it is probably not the best decision to allow it to remain on your PC even if it offers something in return. As we already mentioned, though some programs that belong to the Browser Hijacker category might come with something relatively useful, this can hardly ever compensate the overwhelming intrusiveness and obstructive changes that this type of programs trigger on any computer they get installed on.


Technically, Browser Hijackers are not real malware viruses like Trojans, Ransomware, Spyware, Worms, etc. However, due to their rather intrusive behavior many people tend to refer to them as malware. That said, it must be noted that programs like Cache Killer Chrome are not actually harmful to your PC in the majority of instances. Even if they are irritating and annoying, their purpose is different from the purposes that most actual viruses have.

In reality, most Hijackers aren’t even illegal. Developers of such programs seem to have found a way to create and distribute their products without being considered criminals and hackers and without being prosecuted by the law. This further increases the popularity of this type of software since it is both highly-profitable and also legal at the same time.

Safety is not guaranteed!

Though Hijackers might not be as dangerous as Ransomware or as Trojans, they are still not the safest type of software to have on your PC. The changes to your browser and Internet settings might potentially make your system more vulnerable to attacks coming from the web. Also, the online offers and page redirects that might be coming from a Hijacker could potentially be unsafe and even hazardous. Therefore, we advise you to avoid any contact with anything coming from Cache Killer Chrome in order to prevent any more dangerous pieces of software from getting inside your PC system.

Update: Another thing that we recently learned about this particular Hijacker is that it also tends to gather telemetry data from its users. What this basically means is that it could collect personal information from your browser regarding your online habits and activities. The whole point behind is so that the Hijacker would be able to later use the acquired data to modify the ads that it might display inside the browser. The adverts would be customized so that they seem appealing to the individual user as they would be in line with their interests. For instance, if you search for sports equipment in your search engine, the Hijacker would record your search and later implement this information within its ads. Therefore, more than likely, you will soon start getting ads for sports equipment from different sites . However, you can never know if the ads you see are coming from e reliable source which means that interacting with them could potentially put your PC and online security at risk.

 Additionally, many programs that tend to gather telemetry data might even sell the acquired info to third-parties. Needless to say, you will not be notified about any of this and you won’t really know how your private data might get used down the line.

Distribution of Hijackers and how to avoid them

Browser Hijackers tend to be distributed in a number of ways. Anything from sketchy Internet ads to spam e-mails can be used as a vessel for spreading Hijackers. After all, the more computers that have the PUP installed on them, the greater the profit for the program’s creator. Therefore, you, as a user, need to be really careful with what you do on the Internet or else you might end up landing some unpleasant and undesirable application such as the one we are currently talking about.

Apart from spam messages and sketchy ads inside unreliable sites, Hijackers also tend to get distributed via file bundles. In order to avoid those, never use the regular setup settings when installing new programs. Always go for the Advanced setup and remember to look for added installs. Oftentimes this is where you can find a hidden Hijacker. In case you see an added application that might be unreliable or simply one that you do not need, do not hesitate to opt-out of it before you proceed with the installation of the actual program that you want.
