50 up and 50 down. That's not bad for a speedtest, if this are mbps as you say later.
Since a speedtest is just downloading and uploading and 50 mbps, it's strange that all downloads and uploads are so slow.
it could be a problem with your ISP. So the first thing I should do is to try another PC/laptop and see if that's as slow as your regular one.
It's unlikely to be a virus, I think.
