Safebrowse.io virus removal on Mac


Find out how to get around the safebrowse.io browser redirect issue on Mac and what unsettling implications it may have in terms of security and privacy.

While being arguably the most significant technological breakthrough of all time, the World Wide Web is also a cradle for countless online scams and malicious applications. Vigilance alone may not suffice to avoid these perils, with cybercrime campaigns becoming more complex and elusive at a tremendous rate. Phishing sites can look just like legitimate sign-in pages, and viruses can mimic popular utilities too skillfully to be identified with the naked eye. Instead of going through trial and error, it’s best to outsource a part of security to ad hoc software and services. In fact, modern web browsers come with fundamental protection features that fend off common forms of harmful code and frauds. The same goes for ISPs. The caveat, though, is that false positives can become a fly in the ointment down the road. For instance, numerous Mac users are reporting alerts from safebrowse.io site accompanying attempts to access known-trustworthy web resources.

Safebrowse.io blocking access to a specific site

It should be noted from the get-go that safebrowse.io is an authentic service that stands sentinel over users’ security by blocking access to potentially dangerous sites. The issue of error screens appearing instead of intended web pages is being predominantly reported by customers of Xfinity, a major U.S. telecommunication services provider operated by Comcast. Moreover, the blacklisting functionality that involves safebrowse.io redirects is a central element of Xfinity xFi Advanced Security, a feature that helps users steer clear of suspicious and clearly detrimental sites. It is additionally tasked with safeguarding smart devices in a home automation system against remote exploitation. Sounds great, but there is something about this protection layer that makes numerous users frown: it often raises red flags on absolutely harmless pages.

The threat detection algorithms underlying the service may set off alarm bells when a user is trying to routinely visit popular cryptocurrency exchanges or download arbitrary software they purchased. The URL of the alert page starts with safebrowse.io/warn.html and is appended with the address of the site the person was originally trying to access but failed. In many cases, the following message is displayed:

“Hold On! We blocked access to [domain name] This site might compromise your device or contain dangerous content. To avoid these risks, close this window and skip this site.”

There is a clickable element that says “Proceed Anyway” at the bottom of that page. The problem is that it doesn’t dismiss the alert no matter how many times the frustrated user hits it. Sometimes the page says, “This site can’t be reached” and additionally mentions that the server’s IP address could not be found. In response to a surge in negative customer feedback, Xfinity recommends turning off the overreacting feature if it’s causing problems. To do it, a user needs to sign in to their account, head to a section called “My Services”, and slide the xFi Advanced Security status toggle to the “Disable” position. When done, it’s preferable to wait for about 10 minutes and then check if the previously blocked website is now available.

One more shade of the safebrowse.io issue is in a black hat area. Chances are that malicious code that’s already running on a Mac may tamper with the DNS server settings in order to spoof this URL. As a result, the redirect will look like the ISP’s attempt to protect the user, when it’s actually a malware attack in disguise. If this mimicking trick kicks in, the above-mentioned “Proceed Anyway” button can lead to a virus payload or forward the user to a phishing site that will try to obtain sensitive information while impersonating a trusted organization. Unfortunately, it may be difficult to tell the real blacklisting scenario from the malware-borne predicament. If in doubt, users should ascertain that the warning doesn’t stem from harmful software.

The steps listed below will walk you through the removal of this malicious application. Be sure to follow the instructions in the specified order.

  1. Expand the Go menu in your Mac’s Finder bar and select Utilities as shown below.

    Go to Utilities

  2. Locate the Activity Monitor icon on the Utilities screen and double-click on it.

    Select the Activity Monitor

  3. In the Activity Monitor app, look for a process that appears suspicious. To narrow down your search, focus on unfamiliar resource-intensive entries on the list. Keep in mind that its name isn’t necessarily related to the way the threat is manifesting itself, so you’ll need to trust your own judgement. If you pinpoint the culprit, select it and click on the Stop icon in the upper left-hand corner of the screen.

  5. Click on the Go menu icon in the Finder again and select Go to Folder. You can as well use the Command-Shift-G keyboard shortcut.

    Use the Go to Folder feature

  6. Type /Library/LaunchAgents in the folder search dialog and click on the Go button.

    Open /Library/LaunchAgents folder

  7. Examine the contents of the LaunchAgents folder for dubious-looking items. Be advised that the names of files spawned by malware may give no clear clues that they are malicious, so you should look for recently added entities that appear to deviate from the norm.

    As an illustration, here are several examples of LaunchAgents related to mainstream Mac infections: com.pcv.hlpramc.plist, com.updater.mcy.plist, com.avickUpd.plist, and com.msp.agent.plist. If you spot files that don’t belong on the list, go ahead and drag them to the Trash.

  8. Use the Go to Folder lookup feature again to navigate to the folder named ~/Library/Application Support (note the tilde symbol prepended to the path).

    Open ~/Library/Application Support folder

  9. When the Application Support directory is opened, identify recently generated suspicious folders in it and send them to the Trash. A quick tip is to look for items whose names have nothing to do with Apple products or apps you knowingly installed. A few examples of known-malicious folder names are Quick Mac Booster, IdeaShared, and ProgressMatch.

    Application Support folder contents

  10. Enter ~/Library/LaunchAgents string (don’t forget to include the tilde character) in the Go to Folder search area.

    Open ~/Library/LaunchAgents directory

  11. The system will display LaunchAgents residing in the current user’s Home directory. Look for dodgy items related to [VIRUSNAME] virus (see logic highlighted in subsections above) and drag the suspects to the Trash.

    Go to /Library/LaunchDaemons

  13. In the LaunchDaemons path, try to pinpoint the files the malware is using for persistence. Several examples of such items cropped by Mac infections are com.pplauncher.plist, com.startup.plist, and com.ExpertModuleSearchDaemon.plist. Delete the sketchy files immediately.

Several examples of configuration profiles created by Mac adware include TechSignalSearch, MainSearchPlatform, AdminPrefs, and Chrome Settings. Select the offending entity and click on the minus sign at the bottom to eliminate it.
