Hello everyone! I'm new to these forums and wanted to say hello quickly. Of course I also got a couple of questions - as the title implies - about Nitro and if it's worth it/any risks to worry about, as well as something rather odd.
So, regarding Nitro, is it safe? Are there any risks or things to worry about, would licenses be lost or need to be reset if updated to it, is the non-Nitro version of Avast still supported even? I've been trying to find unbiased reviews(as well as reviews in general) with very little luck. Some also mention issues the moment it installed I think, though the ones I found I skimmed over mostly...
As for the question-mark deal, I noticed this about a week or so ago. Everything works fine, yet there seems to be an odd change to the Quick Scan for my "Scan for Viruses" Option. It's now marked as "

?" and above the start scan button,there is a small, underlined option to "Delete

?" What is this meaning of this, and should I be worried? Has this happened for others here, or is this simply a glitch with the name (it's literally just about the Full Scan option on the list where Quick Scan was).
