What is ‪‎Ransomware‬?

Solution

Ransomware is a form ofmalwarethat effectively holds a user's computerhostageuntil a"ransom" feeis paid.

Everyone has the same questions when they first hear about Ransomware.Is there any other way to get rid of it besides paying the ransom? No — it appears to be technologically impossible for anyone to decrypt your files once the latest generation Ransomware has locked them.

So what can we all do to protect ourselves against Ransomware?

Ransomware viruses infiltrate your computer when you click on a legitimate-looking e-mail attachment or through existing malware lurking on your hard drive, and once unleashed it instantly encrypts all your files

  • Ensure that your antivirus package is updated with the latest version and latest virus signatures - eScan's mail scanner will delete / quarantine any attachments with a .scr file hidden inside .cab/.zip/.rar attachments.
  • Keep your computers backed up on an independent drive or by using a cloud backup.
  • Take those software update and “patch” alerts seriously.
  • Create a 'restore point' for Windows that can be used to restore the system to a known clean state.
  • Beware of the Attachment ! (Remember: Brand-name businesses like SARS and banks will rarely send you attachments). Exercise extreme caution with such emails, never open an attachment from an email asking for verification. Even if an e-mail seems to come from a familiar address, it does not mean it actually is sent by that person or company - this is called e-mail spoofing.
  • When you need to access a secure site, type in the address instead of clicking on the link in an e-mail or document. If you have to click on the link, put your mouse cursor on the link in the e-mail or document to see whether it is actually the address it should be.
