Yesterday we covered how NHS services in England and Scotland have been hit by a large-scale ransomware cyber-attack that disrupted hospital appointments. The malware, known as “Wanna Decryptor” or “WannaCry”, demanded users pay £300 (£230) to unlock their files.
How to Update Windows to avoid Ransomware
Early indications are that this attack relates to a vulnerability in Microsoft Windows. Microsoft has released a patch for this vulnerability, but many users do not have this patch. It is tempting to ignore system requests to update your computer – but these updates are intended to keep you safe and should never, ever be ignored.
Here are instructions on how to update your Windows system to make sure you have all the latest security patches:
How to Update Windows 7
1: Click Start and then select control panel, select system and security
2: Click on Windows Update
3: The update status will be shown. Clicking “Check Updates” in the left-hand pane will force a check for the latest patches.
4: You can select the updates to install by putting a tick into the boxes by each line.
5: Finally, click “Install Updates” and follow the Wizard through to the end.
How to Update Windows 8
1: Make sure your PC is plugged in and connected to the Internet
2: Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
(If you’re using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)
3: Tap or click “Update and recovery”, and then tap or click “Windows Update”. You can type a “w” to bring it to the top.
4: Tap or click “Check Now”.
5: If updates are found, tap or click “View Details”.
6: Don’t disconnect, unplug, or turn off your PC while the update is being installed.
How to Update Windows 10
1: Click Start (Windows Logo) and type “updates”.
2: Press the Enter key, and the updates window will open: in there it tells you when your machine was last updated.
3: Press “Check for Updates” to see if there are any new patches. If there are, you will be prompted to download them.
4: Leave the machine turned on and connected to power and the internet while it downloads the updates. When you next restart the machine, you will be asked if you want just to restart or to install updates and then restart. Select “Install updates and restart.”
Remember some basic rules:
- Do not open email attachments originating from people you don’t know or from people you do know, but are not expecting
- Make sure you have an up-to-date virus guard (we can supply AVG for businesses)
- Make sure your operating system is up-to-date with the latest security patches.
