Source Add

Source Add is a potentially unwanted application designed to take control of your Mac browsers and alter their settings without your permission. The purpose of Source Add is to reroute your searches to pages that earn revenue based on how many of their ads get clicked.

Source Add Mac

The Source Add Virus will try to trick you into allowing it to control Safari.

Browser ads and page-redirects are the worst – they can show up everywhere on your screen at any given time and obstruct your current online activity with their invasive presence. In most cases, you could deal with that issue by staying away from those sites on the Internet that are way to aggressive with their advertisements. Also, ad-blockers can also help you stop at least some of the more common forms of web advertisements. These methods, however, could only work if the ads you are facing are coming from the sites that you visit. On the other hand, if you have a hijacker like Source Add, Search Baron, Bing Redirect in the computer, attached to your Safari, Firefox, Chrome or another browser, then your only option is removing the invasive app in order to stop the ads from showing. Other things you could notice are changes to the search engine service, the new-tab and homepage address, the buttons of your toolbar and to the entries in the extensions manager. These changes combined with the frequent display of nagging pop-ups, pop-unders, flashy banners, redirects to different pages that are also likely filled with ads could all be really unpleasant and make you want to reinstall your browser or switch to another one. The problem is that this would probably not solve anything in the long term. Browser hijackers such as the Source Add app are usually able to install themselves in every browser in your system that you set as default and re-installing your current browsing program is also probably not going to be enough. Another problem is that most hijackers have not visible and easily-accessible uninstallation option which is why you may need the help of the guide below in order to successfully and fully uninstall the invasive software in order to ensure that it can no longer flood your screen with annoying advertisements.

SourceAdd on Mac

SourceAdd for Mac is a browser hijacker that will monitor your browsing habits and analyze the gathered info in order to figure out your current preferences. SourceAdd for Mac will then feed your browser ads based on your supposed interests.

One additional problem related to Source Add and other apps like it that we did not mention above is the fact that it may sometimes be hazardous to keep such an app in your computer. While this isn’t a malicious program like a Ransomware cryptovirus, a Trojan or a Rootkits, the hijacker is still a software component that obviously does things in your system that it hasn’t been authorized to do. In and of itself, this fact should be enough of a reason to doubt the reliability and safety of this software. And if that’s not enough to convince you that the timely uninstallation of the hijacker is essential, consider this: the adverts, the redirects and the banners shown on your screen by the hijacker would mostly have unknown origins. The control over the quality of the commercial materials shown to you is most likely going to be very low. This, of course, means that you may get redirected to shady web addresses with contents that may put your computer in danger. Therefore, if you don’t want to risk getting your system invaded by Ransomware, Spyware, Trojans or other nasty threats, be sure to make use of the guide above or of the suggested professional removal tool in it to eliminate Source Add.

Remove Source Add Virus


We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading ComboCleaner to see if it can detect parasite files for you.

The first thing you need to do is to Quit Safari (if it is opened). If you have trouble closing it normally, you may need to Force Quit Safari:

You can choose the Apple menu and click on Force Quit.

Alternatively you can simultaneously press (the Command key situated next to the space bar), Option (the key right next to it) and Escape (the key located at the upper left corner of your keyboard).

If you have done it right a dialog box titled Force Quit Applications will open up.

In this new dialog window select Safari, then press the Force Quit button, then confirm with Force Quit again.

Close the dialog box/window.



To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading ComboCleaner
a professional malware removal tool.
