I'm encountering these more often. The last two parts of the extension look like this: avi.zix. Another file came with the zix download, an info file. It points you to a page that points you to a page where you'll find a winzix tool. So far so good. When I click to download that, my BitDefender finds crap. Can I tell BitDefender to ignore that? Should I? I'm concerned by the lack of info online about this extension. Doesn't look legit. But I don't know. Thanks in advance for any info.
