Most users have to remove istsearch.com because it acts as a browser hijacker – it takes over the home page and the search provider of your browsers silently. Needless to say, you must remove all programs which may be infiltrated onto the computer illegally. Unfortunately, if this happens, there is a great chance that other disturbing programs are running on the PC simultaneously. In fact, istsearch.com usually travels bundled with programs promoted by fake installers, which is why we are almost certain that you will need to delete some kind of threats, whether they were identified as adware or PUPs. Of course, right now you should focus on the removal of the clandestine istsearch.com.
It is clear that istsearch.com has been developed by APmedia LTD to promote third-party search engines. Therefore, even though the search engine, also known as Spellso, seems legitimate, there is no doubt that it serves some third party. As it has been established before, you may be presented with the ad-supported search results of search.atajitos.com. Unfortunately, if you do not delete Spellso, you are bound to face different advertisements (e.g., pop-ups, banner and sponsored search results), and these are presented by third parties as well. We recommend that you remove any software related to unfamiliar and questionable third parties, particularly software which may corrupt the browsers illegally.
If you choose to remove istsearch.com from the operating system manually, the first thing you should do is inspect the operating system and figure out which threats you must delete. Note that your PC could be infected with other malicious programs. After this, you must uninstall istsearch.com from the computer and remove the undesirable search tool from the browsers. We have prepared the manual removal guides right below. Of course, you should not forget to install legitimate security software as well to ensure protection against other malware. If security software is already active on the PC, we recommend you replace it because authentic software would not have allowed the infiltration of the hijacker.
