Remove Search.nunu-app.com virus (Free Instructions)

Why Search.nunu-app.com search appears in my browser everytime I launch it?

Search.nunu-app.com virus is another browser hijacker targeting Mac OS X users. If you think that Macs are not vulnerable to spyware and malware attacks, you are wrong – they are^[1], but they haven’t become primary targets yet. Search.nunu-app.com browser hijacker is not a malicious program, but it acts like a potentially unwanted one (PUP^[2]). Such programs are usually trying to change browser’s settings without user’s knowledge to start generating pay-per-click revenue^[3]. Of course, all users notice changes in their browsers, especially because Search.nunu-app.com redirect virus alters the address in homepage settings. However, not all users rush to care about such changes, since the web page this hijacker promotes doesn’t look suspicious.

In fact, it looks like a very simple search engine, which can’t pose any threat to the computer. Sadly, it can. Although it doesn’t do damage to the computer system in a direct way, it provides a lot sponsored search results next to organic ones, and it is a well-known fact that authors of browser hijackers hardly ever endorse content their affiliates share on their websites. Therefore, Search.nunu-app.com redirects can take you to insecure places on the Internet, and you definitely do not want to go there. You can be asked to fill out surveys that require entry of personally identifiable information^[4], asked to install shady third-party programs, or, in the worst case, fake software updated filled with malicious files^[5]. So if you care about your safety on the Internet, better remove Search.nunu-app.com as soon as possible. Using a well-known and trusted search engine like Google or Yahoo is always a better idea. For Search.nunu-app.com removal, we highly recommend using Fortect Intego software, although you might also want to try SpyHunter Combo Cleaner or Malwarebytes Malwarebytes.

What can I do in order to avoid installing browser hijackers?

Browser hijackers, just like adware and other potentially unwanted programs spread along with other free applications. It means that these free applications suggest installing additional software alongside them. Although in most cases users have the opportunity to opt-out these additions, they do not do so because they simply do not notice suggestions to do so. These suggestions are typically written in fine print below Default or Standard installation options, but users tend to ignore such details and just proceed with the installation without modifying these settings first. You should switch the installation settings to Custom or Advanced option and then manually deselect all suggested programs. This way, you will prevent installation of unwanted programs and keep potentially unwanted programs away from your computer system.
