Look, it's NOT a virus or any kind of malware. Having been referenced as long ago as 2009, there is simply NO WAY the AV vendors, and even Apple with the built-in malware detection, have dropped the ball and overlooked it if it was.
You really shouldn't be posting screen caps showing off software that reads databases of stolen software keys. Unless you don't mind announcing to the world that you are a software pirate.
Those pop-up windows aren't "active", so I can't tell what app they belong to. When those windows are selected, what application is showing in the menubar that they belong to? If it's Safari, then it'd be helpful to know what extensions and internet plug-ins you have installed.
Right off the bat, I can tell you to get rid of CleanMyMac and CleanMyDrive. I have a very poor impression of that developer and know of a couple cases where their software caused problems.
Apps with names like "Fastest Free YouTube Downloader" just screams "adware". I wouldn't be the slightest surprised if that or one of a few of your other apps are generating those pop-ups. I haven't used VUZE in years, but iirc it's ad-supported and mabey it is popping those ads up.
My recommendation: download AppCleaner and use it to delete the following apps (along with their support files):
Vuze (Transmission is far superior)
Aimersoft Video Converter (I've never heard of these people... something about them sets off red flags in my head here, and Handbrake is free and likely much better anyway)
CleanMyMac
CleanMyDrive
Fastest Free YouTube Downloader
iSerial Reader
RealPlayer (seriously? You have that installed?)
All those DivX apps (VLC handles DIVX fine and Handbrake can convert them. Those apps are pointless.)
Reboot and see if the problem went away. If you did, then you'll know one of them was the problem.
EDIT: you didn't tell us what software is loading on startup. To do so, open System Preferences, Users & Groups, Login Items (for your user account).
