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

If you are have recently been having issues with your browser where there seems to be a constant flood of irritating adverts on your screen during each browsing sessions where the ads don’t seem to be coming from any specific site but rather follow you to whatever page you visit, then you might have an adware app that has recently gotten inside your PC and browser. It is understandable you don’t remember installing anything like that on your computer – adware apps normally get distributed alongside other programs or through other rather questionable methods such as spam messages and e-mails or through misleading online offers and download suggestions. This allows adware to silently sneak inside users’ computers and get added to whatever browser there is on the PC – IE, Edge, Chrome, Opera, Firefox and so on, it doesn’t really matter what the browser is since most representatives of the adware software group are compatible with the majority of browsing programs out there. So, if you are in this same type of situation where you are frequently getting interrupted and irritated by ads that seem to be coming from an adware application that’s inside your browser, it might be a good idea to read the information that the next lines have to offer. Aside from telling you more about the characteristics of the adware software class and how dangerous it might be for your system’s security, we will also show you how you can deal with one of the currently most widespread pieces of software that belong to the adware category – the so-called Diddy Setup “Virus”. Note that removing adware is not the same as uninstalling any other program from your PC. Remember, the developers of adware apps want their unwanted software to remain on your PC for as long as possible since this would potentially effectively bring greater profit from the constant generation of ads happening on your screen. That is why you are rather unlikely to be able to fully get rid of the adware if you try to uninstall it from the Control Panel or from your browser’s extensions manager. As you will see, there’s quite a bit more to be done than that in order to ensure that the pesky app is indeed fully remove from your machine.

Some more information that you need to know about adware

There is actually a surprisingly high number of users with adware apps on their computers that have gotten used to the constant barrage of adverts and are able to still use their browsers, albeit less effectively due to the constant ad interruptions. However, even if you think that there’s no real need to get rid of Diddy Setup “Virus” or of any other adware app on your PC if you are able to tolerate its presence, we must tell you that there is more to adware than the sheer annoyance that might come from such apps which might be considered undesirable. An adware application is not the same as a virus program – it will likely not try to damage the system of your PC like a Trojan Horse would or attempt to take your files hostage which is something that Ransomware cryptoviruses are known for. However, if an adware app is present in your system, then your machine might get exposed to different types of malware if you aren’t cautious and vigilant and if you tend to click on the ads that the undesirable applications streams to your screen. Adware-generated adverts could come from all over the Internet and although some of them might be safe and harmless and actually show you real offers, this might not always be the case. Therefore, remember to keep away from the pesky advertisements and make sure you take the necessary precautions towards eliminating Diddy Setup and never allowing any such apps on your PC again.

Speaking of preventing future adware installations…

As we said in the start of this post, adware apps like Diddy Setup “virus” (or rather their creators) tend to employ different sneaky tactics in order to get onto as many machines as possible as means of maximizing the overall profit from the advertising campaign. That is why, it is essential that you do not trust every too-good-to-be-true online offer that you see and every random spam message you might receive in your inbox. It’s also advisable that you do not download any low-quality or pirated software as those could also carry adware apps with them. Lastly, never forget to check the installation wizards of new programs you want to get on your PC for bundled apps that are optional components of the installation. In case you come across anything suspicious in a program installer and think it could be adware, either uncheck it and then install the main program or simply close the installation wizard and do not finish the installation.
