I wrote this article to help you remove PUP.Optional.WinYahoo Virus. This PUP.Optional.WinYahoo Virus removal guide works for all Windows versions.

PUP.Optional.WinYahoo is a malicious program. As its name implies, it is categorized as a potentially unwanted program. Yet, there is nothing potential in your situation. You are dealing with an infection and this is bad. PUP.Optional.WinYahoo is the perfect combination of useless, incredibly annoying and dangerous. Keeping it in your system is a mistake. The pest will not be beneficial to you in any way. On the contrary. It will keep on bombarding you with tons of issues and problems. In fact, the more time it spends on board, the more problems you face. They will not go away by themselves. No, they will even grow in severity as time passes.

Luckily for you, you don’t have to put up with all of that. PUP.Optional.WinYahoo is completely removable. You can get rid of it in a few simple steps. However, do not let this fact mislead you. You still need to act fast. Giving the infections more time on your machine will end badly. It may not be the most dangerous type of parasite out there but it is not harmless either. If you don’t take immediate measure to remove it, the PUP may even succeed in causing some irrevocable damage. Do yourself a favor and cut its stay short now!

PUP.Optional.WinYahoo meddles. It meddles a lot. As soon as it enters your PC, it starts making modifications in your browsers` settings. It is perfectly compatible with the most popular and commonly used browsers, so whichever one you use, it is infected. For example, all of a sudden your previous homepage and preferred search engine disappear and another questionable domain, which you have never seen before, takes their places. Needless to say, you didn’t approve this reshuffle. You were not even informed of the implementation. And yet, here it is. What is worse it that, once changed, you cannot get back your old homepage and engine. This is because you are no longer in charge of your online activities. PUP.Optional.WinYahoo hijacked them.

The PUP also adds its pesky plugin to your browsers, thus forcing them to generate numerous commercials. Every page that you attempt to visit it completely covered with ads in all shapes and forms. You see banners, in texts, deals, offers, best prices, comparisons, etc. and etc. As you can imagine, all of this destroys your web surfing. You are constantly interrupted and redirected to shady sites. Getting any work done online becomes an impossible task. But your online activities are not the only thing that is ruined.

Your computer, in general, struggles to perform normally. Its speed slows down to a crawl. It lags and crashes all the time. Programs fail to load correctly. It is a real hellish experience. PUP.Optional.WinYahoo basically makes you avoid using your own machine, both on- and offline. Put an end to this immediately. Use our detailed removal guide below and delete the PUP ASAP. Once you do, everything will get back to normal. Don’t waste time.

PUP.Optional.WinYahoo usually travels the web bundled to other programs. Otherwise, you would never allow it to enter. That’s why it tricks you. It relies on your haste and distraction to slip right by you. Next time you install a program or an update, be sure to take your time. Do not rush into blindly agreeing to everything. Opt for the Custom settings as they allow you to see if there are any extra apps which are about to be installed. You are also able to deselect them all. Do that. Such extras are usually malicious and have been appended by hackers. You don’t need them in your system unless you want to deal with their shenanigans later on.
