Every PDF document I save is in Adobe Acrobat because that is the program I use. The Adobe icon was always shown before the file name. I opened my files today and every Adobe icon was changed to an icon that looks like a mini Chrome (I think HTML, but I’m not sure).
New icons below:
I know that I can go into my control panel and change the default settings back to Adobe. I did that.
Corrected icons below:
I’m wondering how they changed in the first place. If HTML (or whatever type of file that was) is connected to Google Chrome in any way, I did just have to uninstall and reinstall my Chrome browser because it was nonresponsive (if that helps).

How did they change? That really can't be answered as there are tons of ways it could have been changed, but here is a rundown of what probably caused it. (but not all)
"Freeware" Freeware is free software that you download, these tend to offer that you change your home page, install software, etc to earn money. Consider running some kind of Adware remover.
"Malware/Virus" It's possible some virus or malware got installed onto your computer and changed all of your shortcuts and messed with your files. Check your shortcuts to chrome and other common applications to check that the point to the correct location, also consider running an antivirus/malware.
Some adware removers are:
Most of these also include an anti-malware/virus tool as well, but I won't recommend them and I'll leave what to use up to you
