According to this email, which claims to be from Microsoft Canada, recipients should follow a link to download a "high-priority" security update for the Microsoft Windows Firewall and Security Center. The message claims that installing the update will help protect the user's computer against "security threats and malicious code".
However, the message is certainly not from Microsoft. Clicking the link in the message will not download a security update. In fact, following the instructions in this fraudulent email will download and install malware on the recipient's computer.
Microsoft will NEVER send you an unsolicited email that asks you to install a security update either by following a link or by opening an attachment. Windows users should always update their Microsoft products via Windows Update.
