Internet connected but browsers won't won't. Plus other problems?

I have an e545 edge thinkpad and a while ago my browser stopped working. I'm connected to the Internet but always says page can't be displayed. Minecraft servers work when I try though. I tried all the commands like flush dns and stuff like that and didn't work. I also have a fake Windows 7 and I can't uninstall ytdownloader.

"I also have a fake Windows 7" - do you mean you have a pirated copy of Windows 7? If so, do you really expect anyone to help you in your crime.

"browsers won't won't" - double negative - this means browsers will. Did you read the question before you submitted it?

You might have to do a clean install of a legal copy of Windows 7. This should solve both the browser and the downloader issues.
