Fun4u ads. How to remove? (Uninstall guide)
What is fun4u?
Fun4u is classified as an adware and a potentially unwanted program (PUP). It is compatible with all the most popular web browsers, such as Google Chrome, Mozilla Firefox, Safari, and Internet Explorer. However, after making a research on this program, it seems that it’s mainly targeted at Android devices. People claim that they are continuously receiving a pop-up alert from fun4u.mobi claiming:
Warning!
You should scan your Android device for spyware. We recommend you download, install and run a full Threat Scan.
OK
This fun4u pop-up tends to reappears continuously during people’s browsing and does not allow clicking nothing else except OK. Consequently, they have to force web browsers to close or take other actions to get rid of those advertisements. In addition to that, this dubious adware may also deliver sponsored advertisements for you when you surf the net. You may receive a lot of pop-ups, pop-unders, banners, in-text, full-page and other forms of ads. If you have already received fun4u ads, ‘Ads by fun4u’, ‘fun4u offers’ or similar notifications, we highly recommend you to ignore each of them because they may try to promote suspicious or even unsafe websites. However, we recommend you to remove this adware not only due to fun4u redirects, but also due to the cookies that it may install and use for tracking information about you. Don’t get us wrong. It cannot collect personally identifiable information, such as banking information, fill name, logins, passwords, etc. However, it can certainly collect your browsing history, search terms, clicks, email address, IP address, PC’s location and similar information. Therefore, we highly recommend removing fun4u virus in order to prevent information leakage, PUP infiltration, and similar issues. The easiest way to get rid of annoying fun4u popup is to run a full system scan with a reliable anti-spyware, such as Reimage.
