A lot of malware, viruses, trackers and everything! Please Help!

So my pc has a problem and it's a very big one. And i decided to download SpyHunter 5 the "free version" as they claim it. Now the problem is that SpyHunter detected about 5000 viruses, malware, etc... in total and to solve it all i need to pay (which i can't with no card) or start a "Free Trial" and it requires a Card to start (which i don't have and also can't get). If someone has a recommendation for some other Antiviruses tell me (also none of the main ones like Norton, Avast, Bitdefender etc... don't work like the virus probably doesn't let me use them i can't even enter their websites.) And if you have some Card with nothing at all on it that i could use just for one time man i'd appreciate it so so much.

Thanks to everyone who helps! Also DM me if you have an answer.
