Greetings!
We appreciate your post in the Apple Support Community.
Recognizing and dealing with malware on a MacBook involves a few steps. Here's a guideline:
- Signs You Might Have a Virus/Malware:
- Unexpected Ads and Pop-ups: If you're seeing ads in places they shouldn't be or experiencing excessive pop-ups, this might indicate adware.
- Performance Issues: A sudden, unexplained slowdown of your MacBook.
- Unwanted Applications: Applications appearing that you don't remember installing.
- Browser Issues: Your web browser's homepage changes without your input, or you notice new toolbars, extensions, or plugins.
- Random Reboots or Application Crashes: Frequent crashes might be a sign of malware.
- Ransom Messages: Messages that claim your data will be deleted unless you pay a "ransom."
How to Remove the Malware:
- Safe Mode: Restart your MacBook and hold down the Shift key until the Apple logo appears. This will prevent any malicious apps from running when the system starts up.
- Check Login Items: Go to System Preferences > Users & Groups > Login Items to see which apps start when you log in. Remove any suspicious ones.
- Update macOS: Keeping your operating system updated ensures you have the latest security patches.
- Check Browser Extensions: Go to your browser settings and check the list of extensions, plugins, or add-ons. Remove any you don't recognize or need.
- Backup Important Data: Make sure to back up important data. In extreme cases, you might need to erase your hard drive and reinstall macOS.
- Stay Updated & Educated: Make sure all your software, especially your operating system and web browser, is updated. Avoid downloading files from suspicious websites or opening email attachments from unknown senders.
