Warning for Apple users – Mac Defender Scam

Apple users should be aware that there is a new attack affecting Macs. If you see a web page or software which offers you “Mac Defender” “Mac Security” or “Mac Protector” it is a scam, and you should not enter any card details. Your computer has been infected by malware which has redirected your web browser in an effort to steal credit card details.

Apple will issue a software update which will remove the malware. Alternatively, you could use the removal tool from Icronic.

  5. Look out for fake messages about virus infection that do not come from your anti-virus software.
  6. Do not install software from websites that you do not know.
  7. When installing software, use the advanced option if available, and make sure to untick any toolbars, browser add-ons or extra software that might be included with it.
  8. Consider removing any software that runs in the background, it will slow you down.
  9. Do not run any software sent to you by email, even if you know the sender.
  10. Don’t click on any links in an email purporting to be from your bank or from Paypal. They are probably fake.
