The digital world has been eagerly awaiting the release of Microsoft's Windows 10 operating system, said to be a big improvement over Windows 8. (There is no Windows 9.) The software started to roll out to consumers on July 29, but it may take several weeks for everyone to get it. Meanwhile, scammers are taking advantage of consumers anxious to get their hands on it. 

A fake but official-looking email that comes from an @microsoft.com email address offers an immediate download of the software. What consumers get instead is a world of trouble.

The email's text prompts the user to download the new software using a .zip file attached to the email. However, if you open the file, what you download is a type of malware called ransomware.

Once the ransomware takes over the computer, the user receives a request to pay up to get their computer back. Payments are normally requested via Bitcoin, an untraceable digital currency.

The scam was originally discovered by Cisco's security team.

The email looks like this.

Microsoft isn't sending new software updates through email, so if you any email that offers one, delete it immediately.

How to avoid malware

Don't open unexpected attachments. Don't click on any attachments from unknown senders or unexpected attachments from software companies. Don't click on download links within an email, either.

Look for spelling errors. Cisco suggests looking for mangled characters or spelling errors within the body of an email when you're unsure about its origin. A fake message may also show up within the email alerting you that the content has been scanned for viruses.

Stay alert. Hackers evolve their scams quickly and often change their tactics to continue to fool users. Even if you don't see any of these signs, be wary of any incoming emails from Microsoft.
