I have a question regarding VPN and whether it's worth using it. I am often on the internet and security is always a concern. I've recently heard that having a VPN makes it much more secure when using internet. Is it true? I've also heard that some people use a VPN for file sharing (like torrents). Does this mean that, thanks to a VPN, even file sharing is anonymous and that nobody, even their internet providers, can see the traffic that took place?
