Errx049.icu is a scam that uses fake alert messages to scare MacOS users and installs rogue system tools without permission
Errx049.icu is the program that causes pop-ups and redirects which state about the questionable malware activity. Unfortunately, this is a scam that uses virus alerts to trick people into thinking their device is infected with malware. In most cases, these messages appear in Google Chrome and on Mac devices, but Windows users cannot be safe from similar scams too. The primary goal of the social engineering-based scams is to install various rogue tools, in this case, Mac Cleanup or Mac Care. The automatic software installation follows the alleged system scan that only shows false results with the list of malware. There is nothing malicious on your device besides the adware-type PUP that causes all the unwanted behavior and scary virus alerts.

Various pop-up messages, security alerts or warning windows like Errx049.icu uses misleading statements to scare people into thinking their machine got infected with viruses and the only solution is to follow up with the suggested installation of a program.
Unfortunately, Errx049.icu virus alerts are not informing about real issues with the device. The initial message and any further indications about possible threats are not legitimate. Immediately after the redirect to this site, a button that supposedly allows the full system scan appears on the browser. Once that gets clicked a supposed system scan begins.
The system scan is most likely fake as the results presented after that. Errx049.icu window claims that the machine is infected with particular trojans or malware and another button that suggests removing those threats appears on the browser. However, when the process is prompted the automatic installation of macOS repair or optimization tool starts.
Errx049.icu may suggest installing various rogue system tools. Multiple reports say that Mac Repair, Mac Security Plus or Mac-Tweak-Pro gets delivered this way. None of these have the proper functionality of removing cyber threats or viruses.[1]

You need to remove Errx049.icu before any additional changes could be made to your device. All those pop-ups or commercial content that gets delivered to your screen constantly may expose you to possibly malicious sites and lead to the infiltration of more severe malware.[2]
Even though Errx049.icu is mostly targeting MacOS users and affects Google Chrome browser, anyone who uses Windows devices can also get affected. There are tons of similar scams that focus on scaring people and delivering fake messages alongside intrusive commercial content.
Avoid insecure software installations
When you browse online and visit various services or websites often pop-up advertisements or banners with commercial content fill up the screen. As harmless it may seem constant clicking on content as such may lead to redirects to questionable or even malicious pages.
Visiting possibly dangerous websites can be the reason for PUP infiltrations. However, a more common technique used to spread adware and similar programs is software bundling. This method is used when freeware providers and PUP developers pack their products together.
When the user skips through installation steps, downloads questionable programs from the internet or p2p services, various applications get automatically installed when the box Allow/Agree is checked. There is a way to avoid cyber infections – Advanced or Custom installation options.
