How do I know when I got a Virus on my MacBook and how do I remove it?

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.

Bitte vereinbare einen Termin online in der Genius Bar des nächsten Apple Stores. Sollte es sich tatsächlich um einen Virus handeln (was ziemlich unwahrscheinlich ist), dann werden die Expert:innen dort ihn sicher und kostenlos entfernen.

Gibt es einen konkreten Anlass für die Frage ?

Viren für macOS sind selten, es gibt mWn nur sehr wenige dokumentierten Fälle.

In der Regel schützen dich die Sicherheitseinrichtungen von macOS. Viel wichtiger ist aber umsichtiges und vorsichtiges Handeln im Web.

Die schlimmste Schadsoftware ist der Leichtsinn, der die Tastatur bedient.

Genau so und:
@ Emilie bitte schau mal nach den Sicherheitsvorkehrungen deines Mac:
