How to Stop Critical-alert.info Ads

To show pop-up ads, Critical-alert.info uses browser notification. Notifications are little messages that websites can send to web browsers. Notifications appear even if you’re not on the site that’s sending them. But you have to allow those notifications first. That must have happened the first time that Critical-alert.info appeared in your browser.

So, all that you need to do is revoke that permission from Critical-alert.info. You can do this in your browser settings. There’s a list of websites that are allowed to send notifications to your browser. To see this list, different web browsers require different actions. If you’re not sure what your browser is, check this page (in the table, the Browser row). Then:

• Chrome – type “chrome://settings/content/notifications” in the address box.
• Safari – in the Safari menu, choose Preferences, Websites, Notifications.
• New Edge – type “edge://settings/content/notifications” in the address box.
• Firefox – open Settings, Preferences, Privacy & Security, scroll down to Permissions, and click on Settings next to Notifications.

You will see two lists: addresses that are blocked from sending you notifications, and those that are allowed. On the list of the latter sites, to the right of each address, click a menu button and press on the Block (or Deny) option. Do this for every site that you don’t want to see pop-ups from.

You can find instructions including screenshots in this post.

After that’s done, it’s important to check your computer for malicious and potentially unwanted programs and browser extensions. If you find any malware, remove it. Sites like Critical-alert.info advertise and are advertised by adware programs, so it’s a big concern to make sure your device is not infected. An easy way to check it is to scan your computer with an anti-malware application (like Spyhunter for Windows, Combo Cleaner for macOS, etc.), then review the scan results by checking the name of each detected item.

Problems With Critical-alert.info

Critical-alert.info only exists to show people ads in their browser. It gets this power by tricking people, and then it uses it to spread dangerous and harmful content.

Unwanted Subscription

Critical-alert.info has pages that do two basic things:

• show the notifications alert with an Allow button and a Block button,
• ask you to click the Allow button.

Someone came up with a bunch of different ways to ask visitors to click the Allow button, including these:

• “tap the Allow button to continue”,
• “click Allow to confirm that you are not a robot!”,
• “click Allow to download”,
• “click Allow to close this page”,
• pages with blurred out images of adult videos.

All these pages are nonsense only meant to trick as many people as possible into clicking that Allow button which allows Critical-alert.info to start sending notifications.

Dangerous Pop-Ups

Anyone can make a webpage that says “Click this button for a prize!” or “Click this button, or else!”. But most reputable websites won’t show ads for such a webpage. So, how does Critical-alert.info spread?

Not all websites care about the security of their visitors. There is Y2mate, Superflix, Flvto, and other controversial or not-quite-legal websites that may have to take on malicious ads to stay afloat. So, they show random pop-ups, redirect you to malicious sites, show obnoxious ads that lie to you or try to trick you. Critical-alert.info among them.

Besides malicious sites, malware on your computer can also cause Critical-alert.info ads to appear, too.

As for what Critical-alert.info advertises, its ads include promos for browser hijackers like ConvertMyVid that take over your browser. It also promotes Bitcoin investment schemes that try to get your money by promising amazing profits. Clickbait links waste your time. Alarmist ads for VPNs and PC optimizers try to trick you into buying software that you probably don’t need. And Critical-alert.info promotes more sites like itself that also spam you with ads.

There is no single solution to avoiding adware like Critical-alert.info. You probably don’t want to stop visiting websites that you’re used to, but you could use an anti-malware application to block malicious sites. You could also use an ad-blocker. That would stop some of the malicious ads and help you stay safe.

Regularly scanning your computer with an antivirus program would also help you stay secure.
