Browser hijackers such as Misarea, Searchpoweronline, Appyrinceaskeda and Captcha Safe Top specialize in producing and displaying all kinds of online advertising materials within the main browser. In terms of maliciousness, these applications are far from, say Viruses, Ransomware or Trojans, but their activities can still be quite unpleasant and a lot of people refer to them as potentially unwanted. The main reason is, such apps tend to mess with the web browsing experience by showing modified search results and by initiating redirects to sites that oftentimes have nothing to do with the actual users’ searches. Moreover, after a certain period of time, the hijacked browser typically starts to work much slower and the system starts to experience lags and freezing due to the fact that a lot of system resources are constantly being spent on generating and displaying online advertisements instead of being used for your other software. Of course, these effects also depend on the power of your processor and RAM but, more often than not, this is exactly what happens. Another reason to uninstall applications like Misarea is the fact that their promotional materials may sometimes put you at risk of being infected with real viruses and malware, even though the browser hijackers themselves typically cannot directly cause you any harm. This is because there are hackers with malicious intentions which like to inject threats like Trojans and Ransomware into different online advertisements and considering how any ads a hijacker is capable of displaying, there is no way to know which are safe and which are compromised. That’s why removing them all is a preventive measure which may save you from a really nasty malware infection.
