For instance, it typically sets a new search engine as the default one and it is, thus, the one to display all your search results from then on. And users also tend to discover that their browser homepage has also been substituted with a different one by the hijacker.

Programs like Simage4.pubmatic.com, Search Marquis, Search Baron also tend to fill your browser with numerous popups, banners, box messages and various other forms of online ads. This happens regardless of the websites you visit. And speaking of visiting websites, you may be forced to visit certain sponsored ones whether you like it or not thanks to sudden page redirects that your browser undertakes without even asking you. This is the activity that usually drives users crazy and pushes them to try and remove the intrusive browser hijacker from their Macs. And thankfully, this is something that you can do in a matter of a few relatively easy steps described in the removal guide below.

Simage4.pubmatic.com for Mac

Simage4.pubmatic.com for Mac acts as an advertising tool. Simage4.pubmatic.com for Mac generates revenue for its developers thanks to all the ads it generates on your screen.

Namely, programs like this typically operate on the basis of remuneration systems such as Pay Per Click or Pay Per View, which speak for themselves. And that is why the process of promoting this product or that service is always so aggressive.

Furthermore, browser hijackers like this one tend to go the extra mile in order to ensure that they are most effective. What you don’t see is that a program like this can actually be recording your browsing activity and using it to tailor the flow of ads to your individual preferences. What’s unsettling is that this information is stored and can be distributed to various third parties for an extra profit.

What is Simage4.pubmatic.com?

Contrary to what many think, Simage4.pubmatic.com is not a virus. Simage4.pubmatic.com is a fairly harmless program that specializes in promoting various web locations, products and services. As described earlier, that is how the developers behind this type of software gain revenue.

However, the above doesn’t mean that software like Simage4.pubmatic.com is entirely safe to have on your computer either. In fact, in the long run it may actually prove to be more of a vulnerability to your system exactly because of the numerous ads and page redirects that it forces you to put up with. It may happen that you end up being exposed to certain threats such as viruses and malware. For example, you could be redirected to a page that’s been compromised by Trojan horse viruses or ransomware.

The Simage4.pubmatic App

The Simage4.pubmatic.com app most probably came bundled with some other program that you downloaded. Hence, you installed the Simage4.pubmatic.com app without realizing it. This could have been avoided if you were to opt for the more detailed advanced settings of the installer and paid close attention to every step of the process.

    If there no longer seem to be hijacker symptoms, there’s probably no need for further actions in Safari. Still, we strongly recommend that you do a couple more things just to make sure Simage4.pubmatic.com won’t return to the browser.

    For starters, click General from Preferences and then examine the address that’s currently set as the homepage of the browser. If that address isn’t the one that the bowser used to have as its homepage before the hijacker appeared on the computer, then replace it with your previous homepage address or with another one of a site that you can trust.

    You must also go to Privacy and there select Remove All Website Data and execute the action. This will help clean any last remnants of the hijacker that may still be lying around.
