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

Though the name of this “threat” might sound scary, the problematic software that we are going to be focusing in throughout the next pages isn’t really some major malware infection caused by some malware the likes of Ransomware, Trojans or Spyware. If you think that you might have the PUP Optional on your PC, then this is most likely due to a warning from your antivirus/anti-malware tool, which has detected some unrecognized and potentially hazardous piece of software on your PC and has therefore warned you about its presence in the system. But what does all of this mean? Is there actually virus inside the computer and should any precautions be taken in order to have it removed? We are about to give you an answer to these questions within the next lines…

What is the PUP Optional Virus?

First and foremost, we need to make clear what PUP stands for. A PUP is an abbreviation for a potentially unwanted program. As you can see, the very name leaves a quite different feeling when compared to terms such as “virus” or “malware”. PUP’s are generally not too dangerous – oftentimes they are actually legitimate or semi-legitimate programs that might even have some useful functions but due to some annoying and unpleasant traits such as aggressive ads generation and unauthorized tinkering with the system and Internet/browsers settings are seen as unwanted. If your antivirus/anti-malware tool warns you about the presence of such software on your computer by showing you the PUP Optional detected message, then this usually means that there is some undesirable but likely not all that dangerous piece of software on your computer that you are advised to find and remove. If you need manual instructions on how to do that, you can use the guide below:

Potential dangers – what to expect?

It is oftentimes difficult, especially nowadays, to tell where the line between a virus and a PUP or the line between a PUP and a legitimate piece of software is. There are many different opinions on the matter and it is not impossible that a program which one user would say is some nasty virus will be a highly-valued and praised piece of software for someone else. However, though it is oftentimes a matter of perspective, you should still know the general dangers that could come with the presence of a potentially unwanted program such as the PUP Optional on your PC. If you have this software, then you are likely to get exposed to different ads and page-redirects in your browser because most PUPs are known for causing that. This advertising activity, aside from being highly irritating, could also potentially land you on some shady sites and pages and thus expose your machine to actual serious malware threats – Rootkits, Spyware, Ransomware, Worms and many others. That’s why it is preferable if you locate and remove the PUP Optional from your machine and then make sure you don’t ever again get any such software installed on your computer by avoiding obscure download sources for new software and by not interacting with sketchy online content.

SUMMARY:

Name PUP Optional
Type PUP
Danger Level Medium (nowhere near threats like Ransomware, but still a security risk)
Symptoms  Invasive ads in your browser and even when the browser is not active, changes to your Internet and browser settings and generally any other intrusive and unusual activity on your PC could also be attributed to this software.
Distribution Method Mainly through software bundles and through the use of spam e-mail campaigns and different social engineering techniques.
