Extremely late response, but this sounds like a pretty standard browser hijacker. One of the most common types of malware these days, basically all it does is install a modified version of Chrome which has various ads and redirects to generate money. Presumably also mines crypto and tracks your passwords and so on. It quietly modifies all your shortcuts to your browser so that they send you to this modified browser instead of your actual browser. Usually your actual Chrome install is left intact, you just have no shortcuts on your desktop, start menu or taskbar that lead to it.
Just running ADWCleaner and Malwarebytes should fix it. ADWCleaner actually even goes through the trouble of restoring your shortcuts. But you can never really know for sure if your computer is clean afterwards, because most people don't know this, but creating malware that goes undetected by all anti-malware software is actually comically easy and a script kiddie could do it with some pre-made tools found on GitHub. There are undetected silent XMR miners which are hard to notice and to manually remove even if you know a lot about this stuff.
You could run something like
TronScript for a thorough cleansing (I cannot stress this enough, read the manual before using it), but if possible, I would just wipe everything and be more careful in the future. Only way you get a browser hijacker is by making a very long series of pretty obvious mistakes. Next time you download a cracked videogame or a cheat tool for a videogame or whatever else, make sure you're at least getting it from a reputable source which has been vouched for by a lot of people in a forum or subreddit.
