Search.searchjstf.com is a shady search engine

Users often refer to this potentially unwanted app as a Search.searchjstf.com virus. However, it’s too strong term to describe this cyber threat. It cannot harm the computer directly, corrupt files or steal sensitive data. However, its infiltration definitely increases a possibility to meet dangerous viruses online.[1]
Search.searchjstf.com can affect Chrome, Firefox or other commonly used browsers and alter their settings. The browser hijacker might also make some changes to the system or install helper objects to keep control over the browser. For this reason, users might find it difficult to get rid of it from the browser.
The PUP alters browsers homepage, default search engine, and new tab URL address. According to the researchers from semvirus.pt,[2] it might set either hxxp://search.searchjstf.com and hxxp://query.searchjstf.com instead of the default browser startup page.
However, this search engine might seem legitimate because it offers quick access to popular social networks and redirects search queries to Yahoo results page. The problem is that authors of the hijacker do not have a purpose of enhancing your browsing sessions. All they want is you to visit sponsored sites or click on ads. However, you should not do it!
Search.searchjstf.com redirect tendencies are really concerning. When you click on a search link, the hijacker might trigger another redirect to the affiliate website. Hence, instead of opening needed source, you might be visiting phishing[3] or infected site.
The same problem exists with ads too. However, here developers use another trick. The PUP can collect various information which allows identifying user’s interests and browsing habits. Based on this knowledge, they can display targeted ads, which means that they might look interesting and useful. But we want to warn that commercial content is usually misleading and you should stay away from it.
As soon as you find out about the hijacked web browser, you should obtain reputable anti-malware software and scan your computer. Our team suggests using FortectIntego for Search.searchjstf.com removal. However, any reliable and up-to-date tool can help you too.
We are aware that not everyone wants to use third-party software to remove Search.searchjstf.com and all its related components. For this reason, we created detailed instructions on how to get rid of the browser hijacker without security program. You can find them below.

Be careful with freeware downloads
Freeware and shareware are the main tools used in hijacker’s distribution. Developers of any free program can include additional apps in a freeware installer for a specific sum of money. There’s no doubt that authors of PUPs are very interested in such marketing and distribution strategy.
The advantage of this technique is that PUPs can be hidden under Quick or Standard settings which do not openly disclose about third-party apps. Therefore, when users decide to use this setup, they give indirect permission to install the whole freeware bundle.
It’s possible to avoid this mistake if you use Advanced or Custom installation of a free program. However, choosing these settings is not enough. You have to read notifications in each of the steps and opt out pre-selected optional apps.
Eliminate Search.searchjstf.com for good
