Frmsepmain is an unwelcome app that can change essential web browser elements such as the search engine, the homepage address or the toolbar. The purpose of applications such as Frmsepmain is to generate pay-per-click income through sponsored advertisements and page-redirects that get displayed inside the hijacked web browsers.


It can be very stressful and irritating to have a browser-hijacking program like Frmsepmain, Go go Tech or Main Captcha Top added to your Chrome, Firefox, Edge or any other web browser since its presence will typically have a huge effect on the way the browser functions.

The homepage may get replaced all of a sudden, hard-to-remove pop-ups, banners and different redirect notifications and links might start to appear on the screen and some suspicious pages may start to open automatically in the browser’s window. All this may quickly make someone who is not familiar with browser hijackers to believe that their device has been compromised with a dangerous Trojan Horse, a Ransomware virus or some other malware.

Fortunately, this is not the case. Apps such as Frmsepmain are nothing but simple marketing tools that have no malicious features and cannot harm the machine they operate on in a direct way. Nevertheless, it is necessary to remember that applications of the browser hijacking type are not deemed secure and should be better avoided.

If you already have Frmsepmain in your browser, it would be safer to uninstall it as this would not only stop the endless stream of aggressive pop-ups, banner ads and similar promotional materials but also will allow you to remove the newly installed homepage, search engine and toolbars and regain full control of your web browser.

How can a browser hijacker program be dangerous?

Given the general inability to cause harm, web users who have apps like Frmsepmain on their computer should still have to be aware of the possibility of an accidental encounter with more serious and undesirable types of software such as Trojans, Ransomware viruses, Spyware, etc. If a browser hijacker is permitted to run freely on your PC for long periods of time, its activities may “help” you get exposed to dangerous web locations, sketchy web ads, misleading offers and links that may contain security hazards of all kinds.

That’s why you have to be very careful with the ads and the page redirects that apps like Frmsepmain display. While most will actually be genuine, under certain circumstances, malicious and deceptive advertisements may find their way through the hijacker’s stream of promotional messages and pop-up on your screen when you least expect it. Clicking on such an advertisement may possibly take you to a malicious website that would then download malware on your machine without any action from your side. T

The main challenge here is that genuine and the deceptive advertisements created by hackers and web links are nearly impossible to distinguish. In certain instances, Frmsepmain may even force you to click on its promotional messages and links by giving you no option to remove them from the screen. Tricks such as placing the ads right in front of your cursor just before you tap on something else are commonly used by browser hijackers like this one in accordance with their attempts to collect more clicks to their sponsored pages. However, such practices may not be safe for the end users. That is why, to avoid potentially dangerous web content, it is safest to remove Frmsepmain uninstall any improvements that might have been placed in your browser.
