What is extrasafe[.]xyz?

extrasafe[.]xyz is a deceptive website, the main purpose of which is to trick visitors into downloading and installing a potentially unwanted application (PUA). The app is apparently capable of removing viruses that this website has supposedly detected.

Commonly, pages such as extrasafe[.]xyz are opened through other websites of this kind, clicked deceptive advertisements, and installed PUAs. In any case, people do not often visit these sites intentionally. Do not trust these sites or download applications from them - use only official websites.

extrasafe[.]xyz scam

There are at least two versions of the extrasafe[.]xyz site (mobile and desktop) - one suggesting that the visitor's device is infected with viruses,  the other suggesting that it might be tracked.

The main goal is to deceive visitors into installing an application (at the time of research, extrasafe[.]xyz promoted apps named Globe VPN-Internet Security and Fireblocker Security - Adblock), which supposedly remove viruses and/or prevent further damage.

Neither extrasafe[.]xyz nor other similar deceptive pages can be trusted, even if the advertised apps are legitimate. All software should be downloaded from official web pages, and never through or from sites such as this one. As mentioned, browsers generally open these sites due to installed PUAs.

Note that promotion of dubious, deceptive websites is not the only problem with the aforementioned PUAs. They often serve ads and collect browsing-related data. They feed users with various ads. For example, coupons, banners, surveys, and pop-ups.

When clicked, these can open untrusted websites or even execute scripts designed to cause download/installation of unwanted apps. PUAs can also record details such as addresses of visited websites, entered search queries, geolocations, IP addresses and other browsing data.

They sometimes access and record personal details as well. Furthermore, developers misuse the data to generate revenue by selling it to third parties (potentially, cyber criminals) or in other ways. PUAs can cause thus problems such as identity theft, issues relating to browsing safety, online privacy, and other issues.

Therefore, all PUAs should be uninstalled immediately and avoided in future.

Some more examples of deceptive web pages are berrigroun[.]com, application-update[.]com and hastopnet[.]com. Typically, they suggest that the visitor's device is infected with viruses, is exposed to problems relating to privacy, browsing safety, etc., and encourages the user to solve the supposed problem with a specific application.

Generally, people download and install PUAs inadvertently, and this is often the reason why browsers open dubious web pages.

How did potentially unwanted applications install on my computer?

In most cases, people are tricked into downloading and installing potentially unwanted apps when developers distribute them using a deceptive marketing method called "bundling". This method is used to trick people by including the unwanted applications into the set-ups of other programs as 'additional offers'.

Generally, information about additionally-included apps can be found in "Advanced", "Custom and other similar settings, however, many users leave the settings unchecked and unchanged, thereby allowing PUAs to infiltrate. In some cases rogue downloads/installations happen through clicking deceptive advertisements, which then execute certain scripts.

How to avoid installation of potentially unwanted applications

You are advised to download all software from official and trustworthy websites. Avoid third party downloaders, installers, unofficial web pages, Peer-to-Peer networks (torrent clients, eMule) and other channels of this kind. Check all "Custom", "Advanced" and other settings available in the setup and decline offers to download or install additionally-included apps.

Do not click ads that appear on dubious web pages (e.g, adult dating, gambling, pornography pages), since they can open untrusted websites or even cause download/installation of unwanted, potentially malicious apps. Remove any, suspicious extensions, plug-ins, and add-ons installed on the browser, and programs of this kind installed on the operating system.

If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

Malware removal:

If unfamiliar processes are running, browser searches are being redirected, fans are spinning loudly for no reason, or fake "Update Safari" prompts have appeared, your Mac is likely infected. Run a full scan with Combo Cleaner for Mac to remove the infection. The full manual procedure below covers cases where automatic removal failed, where you want to verify a scan caught everything, or where the malware has multiple persistence points across LaunchAgents, LaunchDaemons, and Configuration Profiles.

Common Mac malware behaviors

VisibleAdware injection - browser hijackers and fake search engines

The most common Mac malware. Replaces your default search engine, homepage, or new-tab page with a lookalike domain that funnels every query through ad networks before passing it to a real provider. Often arrives bundled with cracked apps, fake Flash Player updates, or "free media player" downloads (MPlayerX, NicePlayer).

Browser showing redirected search results from a hijacked search engine
HiddenLaunchAgent / LaunchDaemon persistence

The standard way Mac malware survives reboots. A small .plist file in /Library/LaunchAgents/, /Library/LaunchDaemons/, or ~/Library/LaunchAgents/ tells launchd to run the malware at every login or boot. The .plist often picks a generic-looking name like com.apple.AdobeFlash.plist or com.system.helper.plist to blend in among legitimate Apple files.

HiddenConfiguration Profile abuse

Configuration Profiles are an enterprise feature - they let an IT department enforce policy on managed Macs (homepage, DNS, certificates, password rules). Adware abuses this by silently installing a Profile that locks the browser homepage, default search, or DNS server at the OS level. Manual browser reset doesn't help - the Profile reapplies the hijack. Check System Settings → General → Device Management (or "Profiles" on older macOS).

System Settings Device Management showing a malicious Configuration Profile
VisibleFake update prompts (FlashPlayer.dmg variants)

"Your Flash Player is out of date" or "Update your browser to view this content." Adobe killed Flash in 2020 - any current "Flash update" prompt is malware. The Atomic macOS Stealer (AMOS) family heavily uses this trick to deliver info-stealers that grab browser passwords, keychain items, and crypto wallet seed phrases. Apple's Software Update never appears as a browser pop-up.

SymptomCryptominer CPU usage

Fans spin loudly, the Mac runs hot, battery drains fast, Activity Monitor shows a process near 100% CPU. Cryptominers run silently in the background to mint cryptocurrency for the attacker. Often delivered via cracked apps from torrent sites, browser extensions, or supply-chain compromises in legitimate Mac software.

Activity Monitor showing a process consuming high CPU
HiddenInfo stealing - AMOS, Banshee, Cthulhu, RustDoor

Modern Mac stealer families - AMOS (Atomic macOS Stealer), Banshee, Cthulhu, and RustDoor are the most active - read browser-saved passwords, cookies, autofill data, the macOS Keychain, crypto wallet seed phrases (Exodus, Electrum, Trezor Suite, MetaMask, etc.), and Apple Notes. AMOS is the most prolific overall, distributed via fake software installers, cracked apps, and fake "Spotlight" or "ChatGPT" sites. Once data is exfiltrated, the malware often deletes itself, leaving little trace - which is why credential rotation in Step 10 is critical even after the infection appears gone.

~5 min
1
Disconnect from the network
30 secNo tool needed

Click the Wi-Fi icon in the menu bar (or open Control Center) and turn Wi-Fi off. If you're on Ethernet, unplug the cable. This stops any active info-stealer or backdoor from sending data out or accepting commands. Keep the network off until you've booted into Safe Mode (next step) - you'll reconnect there briefly to download the scanner.

Why this mattersAMOS-family stealers exfiltrate browser passwords, keychain entries, and crypto wallet seeds within seconds of running. Cutting the network is the only way to stop ongoing exfiltration immediately.
2
Boot into Safe Mode and download Combo Cleaner
5 min

macOS Safe Mode loads only Apple-trusted kernel extensions and skips most third-party LaunchAgents and user login items, so persistent Mac malware doesn't auto-run while you set up the scanner. Network access works normally in Safe Mode.

Apple Silicon (M1, M2, M3, M4)
  1. Choose Apple menu → Shut Down
  2. Wait until the Mac is fully off
  3. Press and hold the Power button until "Loading startup options" appears
  4. Select your startup disk (usually "Macintosh HD")
  5. Hold Shift, then click Continue in Safe Mode
  6. Log in - the menu bar will show "Safe Boot" in red
Intel-based Mac
  1. Choose Apple menu → Restart
  2. Immediately press and hold the Shift key as the Mac begins to boot
  3. Release Shift when the login window appears
  4. Log in - the menu bar will show "Safe Boot" in red

Once Safe Mode has loaded, turn Wi-Fi back on and download Combo Cleaner for Mac. Save the .dmg to your Desktop. You can disconnect Wi-Fi again before scanning if you want extra caution.

Inspect running processes with Activity Monitor
Tool: Activity Monitor5 min

Open Activity Monitor (Applications → Utilities → Activity Monitor, or Cmd+Space and type "Activity Monitor"). Sort by CPU usage to spot cryptominers and runaway processes.

Click each unfamiliar process and choose View → Inspect Process (Cmd+I) to see:

  • Path - anything in /private/tmp/, ~/Library/Application Support/<random-name>/, or with a generic-looking bundle ID is suspicious
  • Code signing - Apple's processes are signed by "Apple" or "Software Signing." Adhoc-signed or unsigned binaries from third parties warrant investigation
  • Open Files and Ports - shows what the process is touching on disk and network
Why this mattersMac malware often picks process names like "CoreServicesAgent" or "WindowServer" that look legit at a glance. The Inspect view shows the actual file path, which is what tells you it's not Apple's.

Map persistence with KnockKnock and inspect the launch paths
Tool: KnockKnock + Finder7 min

Download KnockKnock by Objective-See (Patrick Wardle's free tool, the Mac equivalent of Sysinternals Autoruns). It lists every place macOS malware can persist in a single window: LaunchAgents, LaunchDaemons, Login Items, Cron Jobs, Browser Extensions, Kernel Extensions, Authorization Plug-ins, Mail Plug-ins, Quicklook, Spotlight, and more.

Run KnockKnock and toggle "Filter Signed Items" to focus on unsigned or non-Apple-signed entries. Click any suspicious item to see its file path and code-signing status.

If you'd rather check manually, open Finder → Go → Go to Folder (Shift+Cmd+G) and visit each path:

  • /Library/LaunchAgents/ - system-wide, runs at login for any user
  • /Library/LaunchDaemons/ - system-wide, runs at boot before login
  • ~/Library/LaunchAgents/ - user-level, runs at this user's login
  • ~/Library/Application Support/ - where adware drops its data folder, often with a random or app-mimicking name

Then check additional persistence locations in System Settings:

  • Login Items & Extensions - System Settings → General → Login Items & Extensions. Click anything you don't recognize and remove it
  • Background Items - same panel, "Allow in the Background" section. Mac malware often shows up as a background item with an obscure name
  • Configuration Profiles - System Settings → General → Device Management (or "Profiles" on older macOS). Remove any Profile you didn't install yourself
Pro tipRight-click any suspicious .plist → Open With → TextEdit. The <key>Program</key> and <key>ProgramArguments</key> values tell you exactly what executable runs and from where. Don't delete yet - write down the file paths and entry names. We'll remove them after the Combo Cleaner scan in Step 7.

5
Check /etc/hosts and DNS settings
3 minBuilt into macOS

Mac malware sometimes redirects bank, Apple, antivirus, and update domains to attacker-controlled servers via the hosts file or DNS settings.

Hosts file: Open Terminal (Applications → Utilities → Terminal) and run:

sudo nano /etc/hosts

Legitimate entries are commented with #. Any uncommented IP-to-domain mapping is suspicious - especially redirects for apple.com, icloud.com, your bank, or your password manager. Press Ctrl+X to exit nano without saving.

DNS settings: System Settings → Network → click your active connection (Wi-Fi or Ethernet) → DetailsDNS. Confirm DNS servers point to your ISP, your router, or a known public resolver (Cloudflare 1.1.1.1, Google 8.8.8.8). Anything else has been hijacked.

Why this mattersA clean Mac with hijacked DNS is still a compromised Mac. You'll think you're at chase.com and you'll be at the attacker's clone.

Open the .dmg you downloaded in Step 2. Drag the Combo Cleaner icon to the Applications folder. Open it from Launchpad (or Applications), allow it to update its threat database, then click Start Combo Scan and let it complete fully. Review what it found and apply the recommended actions.

Why this comes before manual cleanupCombo Cleaner removes known adware, info-stealers, cryptominers, and the LaunchAgent persistence files they installed in one pass. Manual cleanup in Step 7 is for anything still left over.

Manually remove anything still present
10 minTool: Finder

Reopen KnockKnock (or revisit the Finder paths from Step 4). Anything you flagged that's still present hasn't been caught by the automated scan. For each remaining suspicious entry:

  1. Note the executable path the .plist references (right-click the .plist → Open With → TextEdit, look at <key>Program</key>)
  2. Move the .plist to Trash
  3. Move the executable file at the referenced path to Trash
  4. Empty the Trash

Then go to /Applications and remove any unwanted apps the malware installed. Common adware-installed app names: MPlayerX, NicePlayer, MyShopcoupon, Advanced Mac Cleaner, Mac Cleanup Pro. Drag them to Trash, then check ~/Library/Application Support/ for any folder with the same name and delete it too.

ImportantSome malware files reappear after deletion because something else on the system recreates them. If a file returns within minutes, you have a remaining persistence point KnockKnock didn't show. Re-run Combo Cleaner or proceed to a macOS reinstall (see end of guide).
Recover - restore browsers and security
~15 min

Reset browsers and clear notification permissions
5 min

Mac adware persists in browser extensions, search engine settings, homepage, and notification permissions. Reset each browser you use:

  • Safari: Safari → Settings → Extensions - uninstall anything you don't recognize. Then Safari → Settings → Search - restore your preferred default search engine. Then Safari → Settings → Websites → Notifications - remove all unfamiliar sites. For a deep reset: Safari → History → Clear History → "all history."
  • Chrome: visit chrome://settings/reset → "Restore settings to their original defaults." Then chrome://settings/content/notifications and remove unfamiliar sites.
  • Firefox: open about:supportRefresh Firefox. Then check Settings → Privacy & Security → Permissions → Notifications.

Review installed extensions in each browser and remove anything you don't recognize, especially extensions you didn't install yourself.

Re-verify Gatekeeper, FileVault, and System Integrity Protection
10 min

Some Mac malware tries to weaken built-in security to make persistence easier. Verify each is on:

  • Gatekeeper (blocks unsigned apps): System Settings → Privacy & Security → scroll to Allow applications downloaded from → confirm "App Store and identified developers" is selected (not "Anywhere"). If the malware added itself to the allow-list, the entry appears in the same panel - remove it.
  • FileVault (full-disk encryption): System Settings → Privacy & Security → FileVault → confirm "FileVault is on for this disk." If it was disabled by malware, turn it back on.
  • System Integrity Protection (SIP): open Terminal and run csrutil status. Output should be "System Integrity Protection status: enabled." If disabled, you'll need to reboot into Recovery Mode and run csrutil enable from there.

Then run macOS Software Update (System Settings → General → Software Update) to apply the latest security patches.

Verify & secure
~15 min + 7 days

Change passwords from a clean device
20 mincritical for AMOS family

If the malware was an info-stealer (AMOS, Banshee, Cthulhu, or RustDoor families are extremely common on Mac), assume every password saved in your browser is compromised. So is your iCloud Keychain if it was unlocked while the malware ran. Change passwords from a different, known-clean device - your iPhone is fine if it's not infected.

Recommended order:

  1. Apple ID first - it controls iCloud, Find My, Apple Pay, and the App Store
  2. Primary email - the recovery hub for everything else
  3. Banking and financial accounts
  4. Password manager master password (if you use one)
  5. Crypto wallet seed phrases - if you store any seed phrase or private key on the Mac, AMOS specifically targets these. Move funds to a fresh wallet from a clean device immediately, before changing other passwords
  6. Social media, shopping, and remaining accounts

Where available, enable phishing-resistant multi-factor authentication (passkeys / hardware keys / authenticator apps) - SMS-based MFA is bypassable.

11
Verify the clean and monitor for 7 days
5 min + 1 week monitoring

Reconnect to the network and run one final full scan with Combo Cleaner. Open System Settings → General → Login Items & Extensions and confirm nothing suspicious has reappeared. Open Activity Monitor and verify no unfamiliar process is using significant CPU.

Over the next 7 days, watch for symptom recurrence: high CPU when the Mac is idle, browser redirects returning, fake update prompts, or unfamiliar Login Items reappearing. If anything returns, you missed a persistence point and the procedure needs to be repeated - or you may have a deeper compromise that requires a clean macOS reinstall.

When to reinstall macOS instead

Manual removal isn't always the right answer. Reinstalling macOS from scratch is the only way to be 100% certain when:

  • The malware reappears after every removal attempt
  • A kernel extension or system-level component was modified
  • Confirmed credential-theft malware ran with admin rights - the system likely has multiple unknown payloads
  • The Mac is used for online banking, crypto wallets, business email, or anything where partial doubt isn't acceptable

macOS reinstall is straightforward: shut down → boot to Recovery (Apple Silicon: hold the Power button → Options; Intel: Cmd+R during boot) → Erase MacReinstall macOS. Back up documents to external storage first, scan the backup with Combo Cleaner before restoring it, and reinstall apps fresh - never restore them from a backup of the infected system.

Important: Manual removal of Mac malware requires care - deleting the wrong .plist or system app can prevent macOS from booting normally. If you're not confident identifying system files from malicious files, run an automated scan with Combo Cleaner for Mac and stop there - that path catches the vast majority of consumer Mac malware without the risk of breaking macOS.
