And again a big ransomware action is going on. Big and well-known companies are flat by a hostage computer. Oops is the devils!

Ransomware is a virus that, once it becomes active, starts to encrypt all your files on your computer's hard drive. Only at the expense of a large amount of money, you will find a key to recover your files from the ransomware criminal gang. If it takes a bit of it. Because you may panic and you will never hear any of the drawers lighter. Prevention is therefore better than healed as always. With a little planning, ransomware is best kept out of doors.

To update

First of all, the most obvious options on a short line. Although updating Windows for most users is not the most favorite activity, it's a very necessary evil. Updates close the most well-known safety leaks over time. You're in fact at risk of an update missing something, or a new problem will be introduced. But that does not weigh up against the loss of all your important documents. Includes unique and indispensable photos. And now we are talking about the last category (photos): Maybe it's not a wrong idea to print your most precious screenshots at a photo center and paste them into a traditional album. Or just stop in a shoe box. Just for the case.

Common sense

Use your common sense. There is no bank in the Netherlands who will send you an email regarding the replacement of a bank card or credit card. Banks are hardly communicating via email. Ignore all those banknotes. Preferably use a spam filter. For example, the copy that default was embedded in your mail software, or in your virus scanner. More practical is the use of your mail or internet service provider's spam filter. Do not forget to occasionally check the spam box through the webmail interface. In case a legitimate mail is accidentally marked as spam.

Especially not click

Resent the temptation to click on links in mails with very nice promises. Usually it's fake and you're being led to a virus-rich site. And never open and never attach an email to an unknown sender. Just never. Make sure you run an up-to-date virus scanner. In addition, there are some simple tricks to find out where an email really comes from. If you offer mail software, make sure the full mail address is displayed in the mail header. If that does not, it often helps to keep your mouse just above the sender's name.


In the attached example, we clearly see that the mail is not from the real Rabobank. First, there is the sender, that is not but All alarm bells must now have gone off. If there is a clickable link in the mail, you can keep your mouse cursor on top of it. Definitely do not click! You'll see - as in Thunderbird here - at the bottom left of the web address that is hidden behind this link. This also clearly does not lead to Rabobank. But usually, the first indication is all the language used in the mail, although it is always better to get poets in it. Also, remember that you will never receive mail from a bank where you are not a customer. In short: be ultra-alert on emails from unknown senders, banks and many other (financial) institutes.
