What is guardapl[.]com?
guardapl[.]com is a deceptive website designed to run scams (it has been observed promoting several). One variant makes false claims that the visitor's mobile device has been infected and, another, that the internet connection might be vulnerable. Both versions use these fake claims to promote dubious software.
Online schemes of this kind are commonly used to promote adware, browser hijackers and other Potentially Unwanted Applications (PUAs) and they can even promote malware (e.g. Trojans, ransomware, etc.). Many users access guardapl[.]com and similar sites via redirects caused by intrusive ads or PUAs already infiltrated into the system.
![guardapl[.]com scam](/images/stories/screenshots202004/guardapl-com-scam-main.jpg)
One variant informs users that their iPhone has been infected and damaged by three viruses. Unless immediate action is taken, the scheme states that the device might suffer more damage. To remove these nonexistent threats, people are instructed to press the "Download and Install" button and download/install the free anti-virus tool from AppStore.
They must then run the installed app and remove the fake malware, thereby repairing the device. The other variant states that the users' internet connections may not be secured. To secure them, they are instructed to download/install the "SafeGuardian VPN". All information provided by such scams is false. Furthermore, the content promoted on them is usually untrusted and can even be malicious. Therefore, you are strongly advised against trusting guardapl[.]com or other deceptive/scam websites.
As well as force-opening deceptive/scam, untrusted, rogue, compromised and malicious web pages, PUAs have additional capabilities. They can deliver pop-ups, banners, coupons, surveys and other intrusive ads. When clicked, these redirect to similarly harmful sites and can even execute scripts designed to download/install rogue software without users' consent.
Unwanted apps can hijack browsers, modify their settings and restrict access to them, to promote fake search engines. Most PUAs can track data. They can record browsing activity (URLs visited, pages viewed, search queries typed, etc.) and gather personal information derived from it (IP addresses, geolocations and other details).
The collected data is often shared with third parties (potentially, cyber criminals) intent on misusing it for profit. In summary, PUAs can cause system infiltration and infections, financial loss, serious privacy issues and even identity theft. To protect device integrity and user safety, remove all suspect applications and browser extensions/plug-ins without delay.

originalsecureus.com, mybestsecureus.com and contentfilled.com are some examples of other websites similar to guardapl[.]com. Endorsing nonoperational, untrusted or malicious software is just one purpose of these online schemes.
They can also trick people into revealing their personal information (e.g. names, addresses, emails, telephone numbers, credit card details, etc.), paying bogus fees, calling fake and expensive support/service lines, and so on.
Popular scam models include (but are not limited to) warnings that the device is infected or at risk, alerts that an essential piece of software is outdated or missing, prize giveaways and amazing offers/deals. Regardless of how they operate, deceptive/scam web pages are simply used to generate revenue for the scammers/cyber criminals behind them.
How did potentially unwanted applications install on my computer?
Some PUAs have "official" download sites, which are often promoted by other deceptive/scam sites, however, they are often downloaded/installed with other products. This deceptive marketing method of pre-packing regular software with unwanted or malicious additions is called "bundling".
Since users frequently rush through download/installation processes (e.g. ignore terms, skip steps and sections, etc.), they can unintentionally allow bundled content onto their devices. Once clicked, intrusive ads can execute scripts to stealthily download/install PUAs.
How to avoid installation of potentially unwanted applications
All products should be researched and downloaded from official and verified download channels only. Unofficial and free file-hosting websites, P2P sharing networks (BitTorrent, Gnutella, eMule, etc.) and other third party downloaders are untrusted and can offer deceptive/bundled content.
When downloading/installing, you are advised to read the terms, explore all available options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, features, etc. Intrusive advertisements usually seem normal and harmless, however, they can redirect to dubious web pages (e.g. gambling, adult-dating, pornography and so on).
If you experience these ads/redirects, inspect the system and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

Mac malware removal and recovery procedure
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).

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).

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.

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.
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.
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.
- Choose
- Wait until the Mac is fully off
- Press and hold the Power button until "Loading startup options" appears
- Select your startup disk (usually "Macintosh HD")
- Hold Shift, then click Continue in Safe Mode
- Log in - the menu bar will show "Safe Boot" in red
Intel-based Mac
- Choose
- Immediately press and hold the Shift key as the Mac begins to boot
- Release Shift when the login window appears
- 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.
Open 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 (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

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 → (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 - . 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 - (or "Profiles" on older macOS). Remove any Profile you didn't install yourself
<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.
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 () 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: → click your active connection (Wi-Fi or Ethernet) → Details → DNS. 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.
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.

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:
- Note the executable path the .plist references (right-click the .plist → Open With → TextEdit, look at
<key>Program</key>) - Move the .plist to Trash
- Move the executable file at the referenced path to Trash
- 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.
Mac adware persists in browser extensions, search engine settings, homepage, and notification permissions. Reset each browser you use:
- Safari: - uninstall anything you don't recognize. Then - restore your preferred default search engine. Then - remove all unfamiliar sites. For a deep reset: → "all history."
- Chrome: visit
chrome://settings/reset→ "Restore settings to their original defaults." Thenchrome://settings/content/notificationsand remove unfamiliar sites. - Firefox: open
about:support→ Refresh Firefox. Then check .
Review installed extensions in each browser and remove anything you don't recognize, especially extensions you didn't install yourself.
Some Mac malware tries to weaken built-in security to make persistence easier. Verify each is on:
- Gatekeeper (blocks unsigned apps): → 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): → 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 runcsrutil enablefrom there.
Then run macOS Software Update () to apply the latest security patches.
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:
- Apple ID first - it controls iCloud, Find My, Apple Pay, and the App Store
- Primary email - the recovery hub for everything else
- Banking and financial accounts
- Password manager master password (if you use one)
- 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
- Social media, shopping, and remaining accounts
Where available, enable phishing-resistant multi-factor authentication (passkeys / hardware keys / authenticator apps) - SMS-based MFA is bypassable.
Reconnect to the network and run one final full scan with Combo Cleaner. Open 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 Mac → Reinstall 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.
