One of the most common signs of spyware is a decrease in your Mac’s performance. Spyware can slow down your Mac, or cause it to freeze or crash frequently. This is because spyware can use up your Mac’s resources, such as its CPU and memory, which can lead to a decrease in performance. Additionally, spyware can also interfere with your Mac’s operating system, which can cause it to freeze or crash.
If you notice that your Mac’s performance has decreased, it’s important to scan your Mac for spyware. You can use a malware scanner to scan your Mac for malicious software. If the scanner finds any malware, it will remove it from your computer.

2. Pop-ups
Pop-ups are a common sign of spyware. Spyware can install adware on your Mac, which can cause pop-ups to appear even when you’re not browsing the web. These pop-ups can be annoying and intrusive, and they can also be a security risk. Spyware can use pop-ups to trick you into clicking on malicious links or downloading malware.
If you see unexpected pop-ups on your Mac, it’s important to scan your Mac for spyware. You can use a malware scanner to scan your Mac for malicious software. If the scanner finds any malware, it will remove it from your computer.
Here are some examples of how spyware can use pop-ups to attack your Mac:
- Spyware can display pop-ups that look like legitimate security alerts. These pop-ups may tell you that your Mac is infected with malware and that you need to click on a link to download a security update. If you click on the link, you may download malware onto your Mac.
- Spyware can display pop-ups that offer you free software or prizes. If you click on the link in the pop-up, you may be taken to a website that downloads malware onto your Mac.
- Spyware can display pop-ups that contain malicious links. If you click on one of these links, you may be taken to a website that infects your Mac with malware.
It’s important to be aware of the risks associated with pop-ups. If you see an unexpected pop-up, don’t click on any links or download any files. Instead, close the pop-up and scan your Mac for spyware.
3. Browser changes
Spyware can change your browser settings, such as your homepage or search engine, without your permission. This can be a sign that your Mac is infected with spyware. Spyware can change your browser settings to redirect you to malicious websites, or to collect your personal information.
For example, spyware may change your homepage to a website that is full of ads or malware. Or, spyware may change your search engine to a search engine that collects your personal information and tracks your online activity.
If you notice that your browser settings have changed without your permission, it’s important to scan your Mac for spyware. You can use a malware scanner to scan your Mac for malicious software. If the scanner finds any malware, it will remove it from your computer.
It’s also important to be aware of the risks associated with clicking on links in emails or on websites. Spyware can be spread through malicious links. If you click on a malicious link, you may download spyware onto your Mac.
If you’re concerned that your Mac may be infected with spyware, there are a few things you can do to check. First, you can check your browser settings to see if they have been changed. If your browser settings have been changed without your permission, it’s a sign that your Mac may be infected with spyware.
You can also scan your Mac for spyware using a malware scanner. Malware scanners are available for free online. Once you have downloaded and installed a malware scanner, run a scan of your Mac. If the scanner finds any malware, it will remove it from your computer.
4. New toolbars or extensions
The presence of new toolbars or extensions in your browser without your knowledge can be a sign that your Mac is infected with spyware. Spyware can install these toolbars or extensions to collect your personal information, track your online activity, or redirect you to malicious websites.
For example, spyware may install a toolbar that contains a search bar. This search bar may collect your search queries and send them to a remote server. Or, spyware may install an extension that tracks your online activity and sends this information to a remote server. This information can be used to create a profile of your online activity, which can be used to target you with ads or malware.
If you notice that there are new toolbars or extensions in your browser that you didn’t install, it’s important to scan your Mac for spyware. You can use a malware scanner to scan your Mac for malicious software. If the scanner finds any malware, it will remove it from your computer.
It’s also important to be aware of the risks associated with downloading and installing software from untrustworthy sources. Spyware can be spread through malicious software downloads. If you’re not sure whether or not a software download is safe, it’s best to avoid it.
