Do not wait but take some action if your Internet browsers are affected by the browser hijacker promoting istsearch.com, also known as Spellso. This search engine changes the home page of Internet Explorer, Google Chrome, and Mozilla Firefox, and the changes are made silently, i.e. without user interference. The search engine is owned and maintained by APmedia Limited, which was founded in 2014. According to the privacy policy of the search engine, istsearch.com does not monitor your online behavior. It does not record your IP address, browser type, the type of the operating system, and search query terms. It is claimed that the search engine calculates the total number of searches performed on the website; however, it does not mean that you can trust istsearch.com. The fact that your browsers have been affected without your permission should be taken into consideration, and we encourage you to remove istsearch.com as soon as you can.

The unwanted changes within your browsers can be made after you download some suspect software installer. Your computer should be protected against malware and spyware so that you can prevent insecure programs and consequences that follow you interaction with those questionable programs.

It is also important to note that istsearch.com does not provide you with authentic search results. The search engine is powered by atajitos.com, which, in addition to its search hits, provides computer users with third-party ads. After replacing your home page with istsearch.com, you will be directed to search.atajitos.com, which displays advertisements related to your search terms. We strongly recommend that you avoid clicking on those advertisements because the search engine is not liable for the content of the website to which you are taken by those sponsored advertisements. If you want to browse the Internet without being provided with third-party ads, remove istsearch.com from the computer and set a reliable search engine as your home page.

Below you will find our step-by-step instructions on how to uninstall ISTsearch, or simply istsearch.com, and change the home page of each browser. However, it is not enough to restore the former settings of the browsers because your operating system needs protection against malware and spyware, and a reputable spyware and malware removal tool is all that you need. We advise you to use SpyHunter because this real-time security program removes istsearch.com in no time and, most important, safeguards the system against other browser hijackers, adware programs, Trojan horses, fake security programs, rootkits, and many other threats.
