What is WinYahoo?

Wrong are whose who claim that WinYahoo is harmful and relate it to a virus. WinYahoo is clearly legitimate and can be used if desired. However, it may be labeled as an adware and a potentially unwanted program because it has been reported to display commercial advertisements during people’s browsing. By the way, it’s important to mention that it may infiltrate computers using unfair techniques. In order to prevent unconscious installation of WinYahoo adware, you should avoid clicking on suspicious-looking software update alerts that may show up during your browsing. Besides, you should check freewares and sharewares for ‘additional components’ because WinYahoo virus is often distributed bundled with free programs (video and audio streaming software, download managers, drivers, PDF creators, gaming platforms, etc.). Once installed, it may corrupt various settings in Google Chrome, Mozilla Firefox, and Internet Explorer in order to activate third-party advertisements. Consequently, you may start seeing sponsored advertisements (‘Ads by WinYahoo’, ‘ WinYahoo ads’, ‘Powered by WinYahoo’, etc.) that may not only annoy you, but may also can make you visit suspicious or even unsafe third-party websites. Besides, we do not recommend using this app due to its ability to spy on you while you are surfing the net. You should not worry about personal information; however, we are pretty sure that you are also not willing to disclose your IP address, PC’s location, email address, search terms, mostly visited websites and similar non-personally identifiable information to third parties. Therefore, we recommend you to avoid WinYahoo virus. If it has already infiltrated your machine, then try using Reimage.

How can WinYahoo hijack my computer?

WinYahoo may be downloaded straight from the Internet. However, security experts have also found it spreading along with various freewares and sharewares. In order to stay safe, you have to remember that not only untrustworthy programs that people seldom download are bundled with ‘optional downloads’. Even well known and trusted programs may be filled with unwanted browser add-ons, plug-ins, toolbars, and extensions. Therefore, no matter what kind of freeware you are going to install, you should select Advanced or Custom installation option and review every check box carefully. You should specifically draw your attention to the notifications alongside which you find check marks that are already marked for you. Usually, it’s a MUST to unmark those check boxes since they may notify your consent to install WinYahoo or another potentially unwanted program, for example, Finding Discount, MindDabble, Boxed Books and many others. By the way, avoid Quick or Basic installation because it’s a tricky way that is commonly used to spread PUPs without even informing people about their presence.

How to remove WinYahoo virus?

In order to stay away from WinYahoo redirects and ads, we recommend you to remove this adware without any delay. As we have already mentioned, it’s a legitimate tool, which means that it may be installed and uninstalled without any difficulties. However, if you have installed it along with another freeware, we highly recommend you to check your PC with a reputable anti-spyware in order to remove other PUPs that might have been installed bundled with freewares as well.

You can remove WinYahoo automatically with a help of one of these programs: Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus, Malwarebytes Anti Malware. We recommend these applications because they can easily delete potentially unwanted programs and viruses with all their files and registry entries that are related to them.
