This page aims to help you remove Zip Cruncher “Virus”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

An adware program is a piece of software that is mainly created to advertise different products directly from within the user’s browser. There are thousands of apps and software elements out there that fit the description of an Adware program. Most such apps can be added to pretty much every browser you could think of. Some common examples of browsers that tend to get affected by adware are Chrome, Firefox, IE, Opera and so on. Although the developers behind many of the popular browsers out there try to implement new forms of protection against unwanted apps like adware to, this category of ad-generating software is still one of the most widespread ones. If you have an adware on your PC, you can expect different pop-ups, blinking boxes, page redirects, banners and other forms of advertising content to show on your screen during each of your browsing sessions. The problem with that is the ads are typically overly obstructive and tend to prevent the user from normally using their browser. Oftentimes, the intrusiveness of the ads could get so severe that one might be utterly unable to reach the site or page they are actually looking for due to the constant generation of random unpleasant apps.

There are tenths of thousands adware applications out there but most of them share similar traits so what applies to one of them would also likely apply to the rest of this category. Currently, one of the most widespread adware apps out there is the so called Zip Cruncher. Many users have complained about this newly released application since it seems to be able to latch onto any browser and spam it with its obstructive and obnoxious ads, banners and pop-ups. Naturally, the user would hardly gain anything beneficial from all that advertising activity. In most cases, the only people who can benefit from such an app are its creators since they earn money from clicks made to the ads and the people whose content is getting advertised. Understandably, pretty much anyone who has such a software piece on their computer would like to have the unwanted application removed. You can find uninstallation instructions for Zip Cruncher in the next guide in case you too are among the many customers who have recently had this app installed on their PC and who are currently seeking methods of removing it.

Why it is important to remove the adware from your computer

A rather big issue with many of the applications that can be identified as adware is the fact that the nature of their ads’ origins might not always be safe. Normally, the developers of adware do not take responsibility for the types of ads their products generate. This means that unreliable and even hazardous advertisements could get shown on your screen if you have an app like Zip Cruncher on your computer. Naturally, clicking on one such unsafe advert could lead to all kinds of issues and you might end up getting your computer infected with insidious malware programs such as Rootkits, Trojan Horses and even Ransomware. A note that needs to be made here is that, despite what many people might think, adware apps like Zip Cruncher are not virus programs. They usually contain no malicious code and are typically not supposed to cause harm once inside the user’s computer. Viruses like Trojans, Ransomware, Spyware and Rootkits are the actual threats that users should be afraid of. In contrast to that, a mere piece of adware is not something that would typically directly threaten your computer in any way. Still, though, as we mentioned, the ads coming from adware apps are still a potential security risk which is why you ought to stay away from them whenever possible and also why you should get rid of the adware if you want to be sure that your computer stays safe.

The methods that adware creators use to spread their apps

A lot of adware programs tend to have official sites and pages where they can be download but, naturally, few would willingly download such software on their computers if they know that it’s actually adware. This is why, the developers of apps like Zip Cruncher also tend to employ other methods such as malvertising, the use of spam messages and software bundling to make sure that their products get to more users. In order to avoid landing such apps in the future, we advise you to never click or open spam messages and their attachments and to never visit suspicious sites, download questionable content and interact with obscure online adverts and offers. Also, never use the Quick setup settings when you want to install a new program if there’s an Advanced setup menu. Use the Advanced menu to see if there are any bundled components and uncheck the ones that look like they might be adware or some other potentially unwanted software component.
