Yahoososo virus. How to remove? (Uninstall guide)

removal by Jake Doevan - - | Type: Browser hijacker

How bad is Yahoososo virus?

Yahoososo is a potentially unwanted program (PUP), which falls into “browser hijackers” category. This program sets a new homepage on Internet browsers (Mozilla Firefox, Google Chrome, Safari or IE). The website it promotes is Yahoososo.com, and it provides a web search engine. Such name for this site was chosen probably with an intention to impersonate the real Yahoo search. Yahoososo search engine pretends to be a reliable utility; however, it is a deceptive search tool that you should never use. We have discovered that it leads users to predetermined third-party websites rather than websites related to user’s search queries. Such web rerouting routine is meant to drive traffic to websites that belong to Yahoososo’s partners. Yahoososo redirects can lead you to all kinds of Internet sites, both secure ones and also high-risk ones. Bear in mind that some third-party pages you might be forced to visit can contain malicious links or infectious files.

What is more, Yahoososo PUP may also start sending pop-up ads and placing banners on web pages during your browsing sessions. We recommend you not to rely on these ads, too. They are created based on your browsing history but do not forget that they can also redirect you to websites you might not want to visit. To sum up, this program is not a malicious one, but it wants you to use an unreliable search engine that can compel you to enter untrustworthy websites. So if you are looking for a good web search provider, you should not choose to use the one Yahoososo browser hijacker provides. To replace your homepage, you have to remove Yahoososo redirect virus from your computer. You can do it automatically (with a help of anti-spyware software like Reimage), or manually.
