AES-NI Ransomware Virus – How Did It Infect Me?

The virus will drop its infectious content in one of the following ways:

  • Emails Spam – The crooks send out legit-looking emails that mask themselves as real companies – PayPal, FedEx, Microsoft, and others. In those letters hides an attachment. This attachment will infect your PC if you download and open it.
  • Clickbait scamming – some sites will include weird advertisements that may be tempting for some users to open. Once you click on them, the files carrying the AES-NI ransomware virus will be dropped onto your PC. If that happens, delete them ASAP, preferably with the help of an anti-malware tool.
