The recent Wannacry/WannaCrypt ransomware attacks have reminded us once again the importance of keeping computers up-to-date since this malware targets particularly out-of-date systems.

Fortunately, Windows 10 computers are immune to WannaCry/WannaCrypt attacks. On the other hand, all other unsupported and supported versions of Windows are vulnerable to this type of ransomware attack, so the safest way to prevent WannaCry ransomware attacks is to install the latest updates on your computer.

If Windows Defender is your main antivirus tool, make sure you install KB4022344: this Windows Defender update addresses a severe security vulnerability that could allow code to be remotely executed if the Microsoft Malware Protection Engine scans a specially crafted file. An attacker who successfully exploits this flaw could execute arbitrary code in the security context of the LocalSystem account.

Windows Defender can block WannaCry ransomware

Microsoft confirms that Windows Defender AV successfully detects and removes this threat capable of stopping you from using your PC or accessing your data.

Microsoft already fixed this vulnerability in security bulletin MS17-010, released in March. If you’ve already installed the updates rolled out starting with March 2017, your system should be secured.

If it’s been a while since you last updated your computer, please do hit the “Check for updates” button. You can also download the latest Windows security updates from the Microsoft Update Catalog website.

Do not delay updating your computer because the next mass malware attack may catch you off guard. Also, don’t forget to install one of these anti-ransomware tools as well!
