Despite the belief that the macOS system is unassailable, users are still not immune to malware. The emergence of increasingly sophisticated viruses, Trojans, adware, and spyware makes even the latest Macs vulnerable. Therefore, they can become a target for attackers. Many Mac users are not prepared for such problems. Thus, it is not surprising that the infection often goes unnoticed. It lasts until the system starts behaving strangely. Still, a proven way to protect your device and completely clean it from malware exists. So, what should you do in case of infection, and what tools can help you eliminate the virus on Mac?
How to Recognize the Problem? First Signs of a Mac Infection
Usually, users do not notice a Mac infection right away. You may notice minor crashes and system slowdowns. Unwanted advertising pop-ups may bother you, or your browser may redirect you to suspicious sites. If you think something is wrong, do not ignore it. After all, malware will always manifest itself in the most unpleasant ways. We are talking about illegal collection of personal data, password theft, and tracking of your actions.
However, despite all of the above, you need to stay calm. Perform a basic check. Namely, turn off your Mac and boot it into Safe Mode. It allows you to temporarily block the automatic loading of third-party applications. This way, you can detect problems that are usually masked in standard mode. We’ll discuss this in more detail in the next sections of this article. But are there other options and actions that can be useful if you don’t want to delay?
How do you get rid of malware on a Mac?
Once you detect the first signs of a potential infection, don’t hesitate to take the next step. Use a specialized tool or service designed for Mac malware removal. Usually, such a service will have clear instructions and a user-friendly interface. That is, one that allows users with different experiences to remove malware from their Macs easily. This is especially true when you need to quickly understand how to get rid of malware on Mac without delving into complex technical details. If you are looking for a way to get rid of malware on Mac, consider using a proven and trusted guide. This way, you can avoid the risk of further damage to your system. Some solutions offer both automated threat removal and tips for manual system cleaning.
Let’s Start with Safe Mode
It’s a special mode of launching macOS. It disables third-party kernel extensions, clears caches, and prevents potentially harmful processes from automatically running. To activate it, follow these simple steps:
- Turn off your Mac.
- When you turn it back on, immediately press the Shift key.
- Hold down Shift until the login window appears.
- Sign in to your account. In the upper right corner, you’ll see the Safe Boot icon.
This mode disables startup items and allows macOS to perform hard disk and caching diagnostics. This lets you detect conflicts you can’t see in normal mode.
What you can do in Safe Mode
In this mode, open System Preferences and check all running processes. If you notice suspicious or unknown names, search for them on Google or Mac user forums. Also, check your autoruns. Go to System Preferences, then Users & Groups, then Login Items.
Manually Check. Clean Up
- Suspicious apps
- Configuration profiles
- Remnants
Remove suspicious apps
Review the apps you have installed in the Apps section. Malware is often disguised as supposedly useful tools, and such programs should be removed without delay.
Check configuration profiles
Go to System Settings and Profiles. If you see any unfamiliar profiles, delete them. They can change Safari’s behavior and install phishing certificates.
Clean up any leftovers
Even after uninstalling applications, system traces remain. These are files in /Library/LaunchAgents, /Library/LaunchDaemons, or ~/Library/Application Support. Only delete items you are sure about.
System Scanning
- Antivirus software
- Built-in tools
- Behavioral scanners
Use antivirus software
After manual cleaning, run a full scan with a modern antivirus program. Modern antiviruses are different because they help clean your Mac from viruses and remove adware and phishing extensions.
The role of built-in macOS tools
macOS has built-in protections. These are XProtect and Gatekeeper. They analyze the installation of applications and block malicious files. However, sometimes this is not enough. In particular, when the user has allowed a third-party application to be installed manually,
Behavioral scanners
Some antivirus solutions use so-called behavioral heuristics. This technology doesn’t just look for known viruses, but observes suspicious activity. If an application tries to modify system files without permission, change DNS, or write to the startup, the program instantly warns the user.
Browser Scan
Most malware targets browsers. Malicious extensions can make Safari, Chrome, and Firefox susceptible. Check all extensions.
- Safari: Settings, then Extensions.
- Chrome: chrome://extensions/.
- Firefox: about: addons.
Remove anything that looks unfamiliar or is installed without your permission.
Reset your browser settings
Sometimes, it is better to reset your browser to its default settings. This way, you can remove malicious changes to the start page, search engine, and redirects.
Prevention. Avoidance
- Constant updating
- Verified sources
- Additional protection
Keep your system up to date
Don’t put off updates. They often fix vulnerabilities that malware exploits. Apple releases security patches regularly.
Use only trusted sources
Avoid so-called free software from dubious sources. This is where viruses are most often hidden. Download programs exclusively from the Mac App Store and official websites.
Use additional protection
If you often work with confidential information and need to connect to open Wi-Fi networks, install a VPN and firewall. Also, consider systems that monitor activity in the background.
Final Thoughts
Despite macOS’s high security, the threat of virus and spyware infection is real. But now you know a proven algorithm of actions: Start your Mac in this safety mode and analyze the processes. Remove all suspicious programs and configurations manually. Use reliable software to clean your Mac completely. Update the system. Install a VPN and scan your browsers. Don’t forget that regular prevention is an effective way to stay one step ahead of threats.
