So we've established that it's great (actually, necessary) to have an up to date anti-malware program installed – prevention is always better than cure, after all. The problem with PUPs and adware is that the majority of anti-virus programs are not all that great at spotting them, leaving you still vulnerable to such infections like this one.
But why? What's the problem and why is your all-singing, all-dancing security software failing to identify PUPs and adware? The problem is that from an anti-viruses' view point a Potentially Unwanted Program is exactly that: it's possibly unwanted - but that doesn't mean that it's a dangerous virus or piece of malware. Your PUP really is just an alternative home page or browser extension meaning that it has a genuine use. But at the same time it can display ads that are really annoying and redirect you to very misleading websites.
Just because you or I prefer to stick with Google or Firefox or Bing, there are actually people out there who like, or at least aren't bothered by, the fact that when they Google their nearest hair salon, they are swiftly redirected to a different search engine or they suddenly get pop-up ads from gyt.coreopt.net. Little do they realize that this search engine will have often been populated with Google's results anyway – but that's neither here or there! Besides, most users think that pop-ups are not dangerous, you just close them and that's it but they can promote dodgy products and trick you into downloading them. Some ads may claim that your computer is infected or that someone is spying on you.
There are yet others who can live with the annoyance of pop-up adverts simply because it means that they get free desktop wallpapers. It's all about the trade off.
And it's exactly this grey area that makes it so difficult for your anti-virus software to search and destroy when it comes to adware and PUPs. My advice would be to remove all adware and potentially unwanted programs that can cause those pop-ups from your computer. Very often, such programs come bundled with more sophisticated adware and sometimes even spyware that can monitor your browsing activity. I've listed a few programs that are known to cause those pop-ups on infected computers, PassShow, KeyPlayer. I will update the list when possible. Please note that there are more than one adware and PUP program that can display gyt.coreopt.net. If you have any questions, please leave a comment below. Good luck and be safe online!
