If you’ve recently been getting messages on your screen, including distressing malware warnings that appear in the bottom-left, and/or if your browser has been acting weirdly, redirecting you to sketchy pages, you might be dealing with something like Review4.in.
This isn’t some dangerous virus that will damage your files or steal your data, but it’s also not something you want in your system. Review4.in is a typical browser hijacker that secretly gains various permissions in the browser that allow it to redirect your searches, modify your browser settings, and even display pop-ups when the browser is closed. And to get your to click on its pop-ups, it may even disguise them as malware warnings from popular antivirus solutions like McAfee and Norton (even if you don’t have them on your PC. Naturally, you shouldn’t trust any such notifications and fake warnings and you shouldn’t click on them.

Review4.in Removal Tutorial
A lot of browser hijackers are surprisingly easy to remove – if you’re lucky, that is. Getting rid of Review4.in might take just a couple of simple steps, so it’s always worth trying those first. If that doesn’t do the trick, don’t worry. There’s a more advanced guide further down, packed with extra methods to wipe it out completely.
Quick Steps to Remove Review4.in
- 1.1Start by launching your browser – whether it’s Chrome, Edge, or Firefox. Open the Settings menu, which you’ll find in the upper-right corner. The icon varies depending on the browser – it may appear as three dots, three lines, or an ellipsis. If you’re unsure, hover over icons to see their labels before clicking.
- 1.2Next, navigate to the Extensions or Add-ons section. This is where unwanted software frequently hides. Carefully examine all installed extensions, reading their descriptions to understand their purpose. Some malicious add-ons disguise themselves with generic names, so be cautious of anything unfamiliar.
- 1.3If you notice anything that seems out of place, particularly extensions that promise to “optimize performance” or “improve security”, they’re likely untrustworthy. Select the Remove or Uninstall button next to any suspicious extensions. Restart your browser afterward to ensure they’re completely gone.
- 1.4Now, go to Privacy & Security > Site Permissions. This is the area where websites request permissions, such as the ability to send notifications or display pop-ups – common tactics used by hijackers. Look through the list carefully, as some permissions may have been granted without your knowledge.
- 1.5If you find any unauthorized entries in the Site Permissions list, click on them and revoke their access. Be thorough and check each category, including notifications, pop-ups, and clipboard access, as hijackers often abuse multiple permissions to retain control over your browsing experience.
Once you have completed these steps, restart your browser. In some cases, this simple process is enough to resolve the issue entirely. If everything appears back to normal, you’re in the clear! However, if unwanted behavior persists, you’re likely dealing with a more persistent hijacker, and further action is necessary.
