Potentially Unwanted Programs are often talked about in conjunction with adware and spyware as they have some similar behavioral patterns. And like adware, PUPs also install themselves in a rather underhand way. PUPs are only potentially unwanted because they do normally have a few useful features; they might be a tool bar or they could be a new home page or search engine. However they can be downright irritating too, severely affecting your user experience when you're online. So, the fact that you are getting this pop-up on your computer may indicate that the system may be infected by other malware as well.
PUPs that feature adware will drive you nuts with their constant bombardment of Windows Version Installer pop up and pop under windows as well as banner ads and other in your face marketing tactics. Some Potentially Unwanted Programs can also cause your PC to run unstably and therefore leave you more vulnerable to security issues. These security loopholes can open doors for malware to slip through - adware is often a lot more dangerous than people often give it credit for.
How do PUPs install themselves?
In most cases, Potentially Unwanted Programs are secretly bundled with another software program. This is often freeware and shareware although you may find you have a PUP installed on your machine from downloading something reputable, or even paid for. However, to lower your chances of installing a PUP or adware, you need to be very careful when you're downloading programs or apps from third party websites.
What problems can a PUP cause?
The majority of PUPs, including those that display "Windows Version Installer" pop-up are browser add-ons, such as tool bars, or adware and, in worst case scenarios, spyware. Potentially Unwanted Programs can cause issues including the following:
- Adware is a nightmare to deal with. Windows popping up all over the place and returning even after you've clicked them to make them disappear. You'll be tearing your hair out within ten minutes of having adware installed on your PC.
- A system that's vulnerable to security threats. When a PUP is running on your computer it can seriously affect your operating system's performance as it may be adversely interacting with other programs you have installed.
- Some PUPs monitor your Internet browsing habits so that they can target the type of adverts you see in relation to your searches. This constant monitoring and dispatching of data seriously slows down your operating system and Internet connection.
- Some PUPs are difficult to uninstall while others, even after removal, may still have certain components left on your machine.
- If you want to protect yourself from the above horrors, install a reputable anti-malware, be careful when downloading and check license agreements for any mention of 'added extras'. And if you do find a Potentially Unwanted Program on your computer... delete it.
