What exactly is PreAmo “Malware”

PreAMo "Malware"

Six fake apps claiming to boost the performance of smartphones are being used to distribute adware named ‘PreAmo’.

PreAmo is probably not the type of software that you would like to get installed on your computer. Sure, apps like this one tend to get promoted as very useful and helpful tools that can be added to your browser and make it faster, optimize it or add to it some new and useful features but the truth is that PreAmo “Malware” is actually what most software security researchers would call an “Adware”. Now, adware is not the worst possible type of unwanted software you could get inside your computer. There are far worse unwanted programs out there – ones like Rootkits, Trojans and, of course, Ransomware. However, you will be amazed at just how widespread the adware category is. There are hundreds of thousands of users worldwide that have issues with nagging banners, pop-ups, pop-under, page-redirects and box messages on browsers like Chrome, Edge, Mozilla Firefox, Opera and oftentimes even on Mac’s Safari. Though the presence of an adware app inside the system is unlikely to directly threaten anything on the computer, it is still undesirable and inadvisable to allow such software to remain in your machine. The sensible thing to do if you have recently noticed that PreAmo has gotten installed in your computer and has latched onto your default browser would be to find a way to eliminate the annoying app. This would effectively get rid of its ads and would clean your browser from any changes that the adware may have made to it in order to boost its advertising capabilities.

It is no secret that a big percentage of the advertisements that get generated on the Internet are not really reliable and some of them may even be hazardous. It’s also widely-known that hackers oftentimes tend to make use of misleading online requests and adverts in order to trick more and more users into unknowingly downloading viruses, Spyware, Ransomware and Trojans on their machines. Now, although an adware like PreAmo or is unlikely to be specifically programmed to show you such compromised or misleading ads, it is also not beyond the realm of possibility that such advertisements indeed get generated on your screen during your browsing in case you have adware on the computer. This brings us back to the importance of removing any ad-generating piece of software that you may find in your system and browser. Keeping your system safe should be a top priority for you, especially if you need the computer for your work or education, which is why we once again mention the guide from this page and the specialized removal program that has been linked to here – use them if you need in order to uninstall the adware.

Achieving a full uninstallation of the adware where you are sure that there’s nothing left of it inside the system may be a bit tricky. The guide below should help you with that but in case the annoyance continues even after you’ve completed the steps, you are advised to use the recommended removal program from the guide for best results.
