@MayankParmar, No, not download.
I'm not sure if Invalid Traffic necessarily means Clicks. I heard that it can also mean bad overall traffic even if clicks are legit.
I have 2 sources of concern, one is click related other is "traffic quality" related:
1) I had an RPM Increase (CTR ~2x, CPC ~3x) that started near Black Friday and still haven't ended. Potentially it could be a click bot but if so why did CPC also increased. If it was a click bot then only CTR would increase I guess. Also against this version stands the fact that I know at least 1 other person who is having similar picture (RPM increase and huge deduction) but his site is in absolutley different language, targets different audience, has different topics and he even has it for mobile traffic only while I have it for desktop version of my site. It's unlikely that we both were hit by different click bots at the same time.
2) Throught November and first half of December I was constantly hit by someone's bot up to 20k times a day all from one same IP address. Then I blocked him in the firewall around Dec 15.
I don't use Ad Balancer, I just manually left 2 banners above the fold. CTR is 1-2%.
What exactly caused the deduction I don't know. I guess I'll find out on Feb 1 if I won't get banned until that date.
