Now that you can edit the file, you can start typing in your text, adding images, and customizing your label. Avery hopefully won’t be loading their Word docs with viruses anytime soon. I scanned a couple of the files myself with an anti-virus program and they were clean, so it’s just a warning in case you downloaded a file from a malicious website. Since the file has been downloaded from the Internet, Word doesn’t trust it and you have to click the Enable Editing button manually to edit the file. The only issue that comes up is that you might get a message from Word saying the document has been opened in Protected View. Open the file and you’ll see the template is ready to use in Word.
If you download only the template, it should be in DOC format. Make sure to select the Template only option otherwise it downloads an installer that tries to install crapware on your system. Click on the one you want and you’ll be able to download it.
