After installing Unchecky my ineternet is solw, whats going on? and sould i uninstall it?

Unchecky shouldn't affect the internet speed. The only internet activity it does is checking for updates once every 24 hours.
Of course, you can uninstall Unchecky and see whether that helps. Then, you could reinstall it if you find out that the issue is unrelated to Unchecky.
