One of the benefits of being a Mac user is that generally you don’t have to worry about spyware, malware and viruses quite as much as a Windows user. In fact, until I ran across MacScan, I honestly didn’t even know there was a spyware scanner for OS X. Well it turns out there is – so I gave a run. The following tutorial will guide you through using MacScan to check your Mac for spyware, malware, tracking cookies etc.

Checking your Mac for viruses. OS X does a pretty good job of stopping viruses and malware from attacking your computer. But there are steps you can take to further protect yourself. Nov 14, 2017 If you want to remove malware, spyware, and other garbage software from your Mac, we recommend you download and run Malwarebyes. The free version is fine if you just want to check for and remove malware. If you want something that runs in the background, automatically scans your downloads, and monitors your system, you’ll want the paid version.

Nov 17, 2006 1. There is commercial keystroke logging software for OS X. There's one app that I know of. Though it doesn't install itself, keystroke loggers tend to be thought of as spyware. There are unconfirmed claims of a handful of other spyware apps out there for OS X. I don't believe any can jump across the Interweb and infect your machine, though. Remove 'mac os is infected with spyware' virus related Safari extensions: Open Safari browser, from the menu bar, select ' Safari ' and click ' Preferences.' In the preferences window, select ' Extensions ' and look for any recently-installed suspicious extensions. When located, click.
To expand a bit on my introduction – first, and most importantly – there are benefits to being an OS X/Mac user. There are benefits to being a Windows user, and benefits to being a Linux user. I’m a firm believer that the “best” operating system is the one that works best for you. That Macs are generally less of a target when it comes to spyware and malware is one of their benefits. So – do you really even need a spyware scanner if you’re using a Mac? I guess that depends on your situation. If your Mac is used in a business production environment, you have incredibly private files, or you just want to rest knowing that your Mac is as secure as you can make it – then sure, it’s worth laying down $29.99 (USD) for MacScan. The big bonus is that there’s an (almost) fully functional demo available, so you can give it a try before you buy. With all of that said – here’s how to check your Mac for potential baddies using MacScan.
- Download MacScan, the demo. Installing MacScan is a breeze – you’ll click next a few times, and that’s it. After it’s installed, locate it in your Applications folder. Double-click the MacScan application to launch it.
- Right away you’ll be asked if you want MacScan to run in authenticated mode. Click Yes.
- And enter your password when prompted.
- If you’re using the demo, now’s the time it’ll remind you of that fact. Note the limitations of demo-mode (no custom scans, no scanning CDs, DVDs or external hard drives). Click Demo to continue.
- Finally, the main MacScan interface.
- Click the Scan button. The screen offering different types of scans will open. Review the info on the Quick Scan page. Essentially, it will scan your home folder, and that’s it. Select the Full Scan tab.
- As its name indicates, full scan will scan your entire hard drive. And now click Custom Scan. Click the Info button on the top menu.
- Custom scan allows you to specify which folders are scanned. Since we’re using the Demo version of MacScan, this feature is disabled.
- From here you can review and get some basic info on the various types of spyware that MacScan will detect. Select an item from the drop down list, and its description will appear in the main menu. When you’re done reviewing, click the Prefs button in the upper-right corner of the top menu.
- Place a check in the box labeled Detect remote administration programs. Note: this is disabled by default, because there are a number of legitimate applications that MacScan might pick up on and notify you of. You won’t necessarily want to delete or disable these, as they may in fact be running intentionally. Click OK to continue.
- Again click the Scan button, and select Full Scan. Click ScanNow sit back and wait. And wait. In fact, go grab a coffee, cause this will take a while. My MacBook Pro has 850,000 files (give or take) and it took about 20 minutes for a full scan to complete.
- In the end, it found 21 tracking cookies. As I mentioned earlier, Macs have a great history of being relatively spyware free (certainly vs. Windows). I’ve downloaded freeware, shareware, software in development etc – from all across the Internet. I’ve jailbroken my iPod Touch using every possible method. And MacScan returned nothing but tracking cookies (which are certainly annoying, but far less harmful than a trojan horse or resource hogging spyware/malware).
- Select an item from the list, and its description will be displayed in the lower window. Click the Isolate button to remove the items MacScan finds. Note: again – be sure that MacScan didn’t find a legitimate remote administration program – if it did, unselect it before you click Isolate so it’s not accidentally deleted.
- MacScan will now confirm that you really do in fact want to delete the items it found. Click Yes to do so.
- Now click Done to return to the main menu.
- MacScan provides a nice little report of its history (last time a scan was run, number of items found etc). That’s it – you’re done! Now you may want to scan your Mac for viruses.
One of the best things about macOS is that it’s incredibly secure and gets far fewer viruses than other operating systems. However, that doesn’t mean it’s immune. There have been plenty of incidents of malware harming Macs in recent years. Thankfully, though, it’s still relatively rare for Macs to be infected with spyware and when it happens, it’s no too difficult to get rid of it.
The recent controversy over Cambridge Analytica accessing the Facebook profiles of tens of millions of users has made the importance of our private data headline news. However, while Facebook providing access to your data to third parties may be undesirable and possibly unethical, it’s not illegal. On the other hand, using spyware to access information about you is illegal in many countries.
What is spyware?
Spyware is malicious code that finds its way onto your computer and then sucks up personal data — that could be personal information about you, financial details, keystrokes, web browsing habits, or even images from your webcam.
There are four main types of spyware:
Check My Computer For Spyware
1. Adware
Adware is probably the most common type of spyware. It’s also the most obvious, because the information gathered by the spyware is used to display adverts or pop-up windows. It’s very frustrating and hugely inconvenient, though it’s unlikely to do real damage to you or your Mac.
This is what adware actually looks like
As you can see it executes commands to 'download offers' that a user will see on their computer.
2. Trojans
Trojans are files that look legitimate, like software updates or movies and they’re designed to fool users into downloading them. Once you’ve done that, they will access your personal data and could do serious harm to your Mac.
3. Cookie trackers
Cookie trackers are similar to adware in that they are used to track your browsing habits and web searches. That information can then be used to display adware or for any other reason the hacker chooses.
4. Keyloggers
![Check Mac Os X For Spyware Check Mac Os X For Spyware](/uploads/1/2/6/6/126605649/598109285.jpg)
A keylogger is a piece of code, installed usually without the user’s knowledge or permission, that tracks what keys are pressed. By doing that, the keylogger can gain access to personal data such as usernames, passwords, credit card numbers, and other sensitive information.
How to remove spyware from Mac
Thankfully, while spyware is very annoying, and potentially damaging, it’s usually not too difficult to remove.
1. Scan your Mac with CleanMyMac X
Use a dedicated tool like CleanMyMac X to find and neutralize spyware on your Mac. CleanMyMac removes not only spyware but all other malware threats, such as ransomware, worms, and cryptocurrency miners. Therefore, when you scan your system with CleanMyMac X, you may be sure that all vulnerabilities will be identified.
Here’s how to use it:
- Download the free version of CleanMyMac and launch the app.
- Choose Malware Removal tab.
- Click Scan.
- Click Remove.
Talking about CleanMyMac X, I can't recommend its Malware Monitor feature enough. Checking your Mac in real-time, it notifies you when there is a risk of spyware infecting your machine. What it does exactly is monitor Launch Agents and other places on your Mac for any unauthorized presence. That's a bit like gatekeeper.
2. Update your Mac to the latest version
![Check Mac Os X For Spyware Check Mac Os X For Spyware](/uploads/1/2/6/6/126605649/668814807.jpg)
macOS has built-in tools to remove known malware, including spyware.
- Go to the Apple menu and click About this Mac.
- Click Software Update. You’ll be taken to the App Store. If you’re not running the latest version of macOS, you’ll see a software update waiting to be installed. Click Update and follow the instructions.
- If you are running the latest version of macOS and no update is available, restart your Mac. When it restarts, it will scan for known malware and remove it.
3. Check your Applications folder
Go to the Applications folder on your Mac and look for applications you don’t recognise. If you see any, you should uninstall them. However, don’t just drag them to the Trash, that won’t uninstall them properly and will leave potentially harmful files behind. Instead, use an app like CleanMyMac X to uninstall them.
CleanMyMac uninstalls applications completely, removing all traces of it from your Mac. You can download it free here. Once you’ve downloaded and installed it, do the following:
- Launch it from your Applications folder.
- Click on Uninstaller in the Utilities section.
- Scroll through the list of applications until you find the one you want to get rid of.
- Check the box next to it.
- Click Uninstall.
3. Get rid of browser extensions you don’t need
Some spyware is installed in the form of browser extensions. These are mini-programs that run alongside web browsers like Safari and Chrome and provide additional features. They can be very useful, but they can also be troublesome if they’re installed without your knowledge or permission.
Here’s how to get rid of Safari extensions you didn’t install or don’t need:
Remove Spyware Mac Free
- Launch Safari.
- Click on the Safari menu and choose Preferences.
- Click on the Extensions tab and look through the list of extensions. If you see one you didn’t install or don’t want, click on it and press the Uninstall button.
- Repeat for every extension you want to uninstall.

The process is similar for Chrome.
Check Mac For Spyware Malware
Along with browser extensions, it’s also worth getting rid of cookies you don’t want as well. And the app we’ve mentioned above, CleanMyMac X, can help you with that:
- Click on the Privacy tool.
- Click Scan.
- Click on the name of the browser whose cookies you want to delete.
- Click the drop down arrow next to Cookies.
- Check the box next to the cookies you want to get rid of.
- Click Remove.
The last resort is to restore from a backup, either Time Machine or a third party backup tool. Assuming you’ve been running a regular backup schedule, you can just choose a snapshot from just before you noticed the spyware and restore from that. You should copy any documents you created or updated since the snapshot to another storage drive or online service first.
Spyware sounds scary and it can potentially damage both you and your Mac. However, in most cases, getting rid of it is not too difficult. And with the help of CleanMyMac X it could actually be very easy.
