From adware and spyware to viruses and Potentially Unwanted Programs like PUP-FNK, it seems we're under constant threat when we're using the Internet. PUPs are just one more annoyance that, whilst not being downright dangerous, are still something many of us don't have the time or the patience to deal with.
What are Potentially Unwanted Programs?
Potentially Unwanted Programs are software that installs itself without warning on your computer. They are most usually tool bars, browsers extensions and home pages. PUP-FNK, however, is a slightly different variant that is responsible for just one or few components of particular adware. Since there are many adware programs you will have to identify it yourself. It could be Yontoo for instance.
There are virtually innumerable different variations of PUP-FNK and unless you want the hassle of constantly trying to get rid of them when you're working, playing or browsing online, you should really find out a little bit more about them. For example, how do PUPs get on your machine in the first place and, crucially, what you can do to stop them.
What can PUP-FNK do to my computer?
As mentioned, PUP-FNK is a program that has been designed to target your PC with unwanted tools or applications. They can also install an adware component on your machine which will display endless pop-up, pop-under and banner adverts. There are other Potentially Unwanted Programs which even install additional software on your computer which, when you're searching online, will direct you not to the website you're looking for but to another one that the software developer wants you to visit instead. How annoying is that?
Is PUP-FNK a Virus?
Technically speaking, it's not a virus. That's not to say that it doesn't still exhibit some unpleasant behavior. And it's not just the browser hijacking antics or the new un-user-friendly tool bar, because it can also have a detrimental effect on your user experience. Think about the pain of having to constantly close reoccurring pop-up ads and never being able to get to the website you need to look at because you're always being redirected to rogue URLs.
Why Create a Potentially Unwanted Program?
Software developers create PUPs like PUP-FNK to generate revenue through advertising. Many PUPs contain adware so the developer can manipulate SEO (Search Engine Optimization) techniques and direct visitors to websites they have a vested interest in.
How did this infection get onto my PC in the first place?
Most likely it's when you downloaded some free software; a TV series, a tool that correctly displays non-Romanized characters on your PC etc. PUPs will be bundled with this software allowing them to sneak onto your PC.
How can I avoid PUPs?
Crucially you need to be alert when downloading software. Read the license agreement carefully and uncheck any boxes that say you agree to download any 'added extras'. These sneaky developers will try anything to surreptitiously slide their PUP-FNK past you!
