DANGER!
Downloaded it from their website; scanned it with Avast Premium (no viruses); installed it and wanted to download an app to use on my PC. Required me to use their "browser" / built-in GUI to access Google Play - but had to input my Google Acct info. Minutes later, my Gmail acct indicated someone about 15 miles from here had used logged into my Google Acct (Gmail asked if it was me). Immediately I reset my pwd for my Acct and UNINSTALLED NOX. Short answer: DON'T GO THERE!
