I failed to not install an adware...

I can't believe this happened to me. As a tech geek, I'm really horrified of adware. I need to avoid them as good as I can, since it basically hijacks your favorite browser's search, put unwanted ads, and slow down boot time. Unfortunately, I failed this time. I accidentally hit that Next button before I install a software from SourceForge. I shouldn't have trusted it anymore since it puts adware since 2013. That site turned into a hell, and they'll try to infect your PC with adware as good as possible.
So I downloaded this FileZilla for some random stuff I should try on my old Xenom laptop I bought in Jakarta a few years ago. Figuring out that I need to go to SourceForge to get it, I need to be prepared of what would happen next: fighting with adware "next" button.
I downloaded the installer, which is an online one (file size is around 800KB), and it uses the adware-delivering SF installer. I clicked on next on each stuff, not knowing that the worst would happen...
I saw this adware named Hao123, and I accidentally clicked on the next button, since I was in a kinda hurry. I tried to go back, but the installer is already going. I'm totally screwed. I know that adware would screw up my search engine and my homepage. I wanted to turn it off by holding the power button or removing the battery, but I'm worried that it would create a bad sector on the HDD. I couldn't do nothing. My expression is blank, knowing that I've screwed up my laptop.
A minute later, it finished. I literally cried for a few minutes after seeing this. Sure enough, my Firefox home page changed to hao123.com and it hijacked my search engine to hao123 too. There was a hao123 program on my desktop, and I cried seeing this. I know that crying won't change anything so I downloaded Malwarebytes and AdwCleaner from Bleeping Computer, scanned and removed them, and after it finished scanning, I turned the laptop off. I just can't believe what has just happened. I used to be very smart on dodging this kinds of adware, but I just horrifyingly failed this time.
Even though it was removed, I can no longer see the fresh condition of Firefox and the registry. It might've left some stuff behind, that I don't actually notice, but it still haunts me whatsoever.
Now I got a lesson: Don't try to download adware-infested installers if possible, and if you really need it, you need to be extremely cautious and try to check everything before installation.
