Uninstall Cucumberhead “Malware” (for Mac/OS X and Windows)

This page aims to help you remove the Cucumberhead “Malware.” The Cucumberhead removal below works for both Mac and Windows-using machines. Although Cucumberhead is frequently called “malware” by users who have a hard time understanding what it is, it is not actually one. Despite us calling Cucumberhead “malware”, this was done for expediency before we can properly convey that this is an adware, an advertising program that is not actually illegal – and malware always are.

These days it’s popular to call every single dangerous piece of software a virus, but are they all viruses and there are other types of unwanted programs. It’s common that when a user experiences an infection for the first time they name it as a virus and search for answers on the net using the same word. Technically, things aren’t as simple as calling everything a virus. In the last few years, hackers have started developing programs with different purposes and goals in mind. It has reached the point where computer threats started to differ a lot between themselves. And with that, security expert decided to name some of them with different names, according to their nature. One of such programs is the one you are most likely a victim of, Cucumberhead.

This will benefit you greatly, such as knowing what to avoid in the future to prevent another infection, such as the one that you are currently dealing with. It’s always better to prevent something happening in the first place, rather than having to deal with it once it’s too late.

Cucumberhead, as you have probably guessed up to this point, is an application that is different from a virus. In fact its type has a name of its own, Adware. These things usually tend to be the same, or very similar in nature, and the only thing differentiating them is their name. As such, we are going to talk about Adware in general rather than Cucumberhead specifically, as its same thing. These software are always created with the purpose of filling your favorite browser such as Chrome or Firefox with obnoxious ads. Doing so has several benefits for the person responsible. One of them is gaining revenue every time someone clicks on one of the ads. This is defined as a pay-per-click advertising model and is one of the major ways for companies to pay back the people who allow placement of their ads on their websites. Every time a user clicks, a small amount of money gets sent to the website that the ad is located on. In most cases this is the creator of the Adware that has signed an affiliate agreement with the stores it advertises for. Unfortunately, many times these programs also link to known attack sites.

In terms of symptoms caused by Cucumberhead, one can experience several levels of annoyance when going about his daily browsing.

  1. When you open a page, the software places ads in different shapes and sizes.  One of the forms they take are the banners. Placed on the sides of the main content area, they are not as obstructive as the rest, but tend to be rather large to compensate for that fact.
  2. Next are the in text ads. You might notice that some of the words in the text that you are reading seem to have a different color. That’s because they are hyperlinks leading to dangerous websites. Sometimes, just by hovering your mouse over them, they might change shape into the last and most annoying of the bunch, pop-up ads.
  3. Pop-up ads are almost always big, obstructive images that carry some sort of advertisement.

Perhaps the worst of the things that Cucumberhead is capable of is the fact that they tap into your browsing related information and sent it back to its creator. Once it his hands, they go through an algorithm that helps the Adware by feeding it ads that are better suited to your tastes and preferences. You might see someone you’ve yearned after for a long time. Do not be fooled! This is almost always a fake offer in the hopes of making you click on it.
