Can ISPs block one device (my PC) from the internet?

Lol, no and no. In theory they could likely get into your router and perhaps blacklist a MAC address, but it's not something they would do for "watching porn" (or at all).

Change your MAC address on your network card. If the internet magically starts working again, then its possible, but also just as likely to be an ARP Cache issue.

Have you restarted the router at all since the problem began?

Haha thanks, it's just that the internet went dodgy a day after I watched porn on my computer for the first time, thus leading me to believe that's why my internet was not working. And I have tried practically everything, router restart, command prompts, change of Ethernet cable etc. But has not tried to change MAC address. Are you sure they can't ban 1 device from the internet (btw I'm panicking so I want to be thorough lol)

Like I said, in theory they "could" blacklist a MAC address on your local router, but not from "the internet", as all of your devices will be presenting themselves to "the internet" as the WAN interface's MAC address of the router (this is how NAT/PAT works). The two ways to prove or disprove that your MAC address have been "banned" (blacklisted, blackholed, added to an access-list, etc) would be to change your MAC address, or change your router (stick it in modem mode and use another router behind it for example). You could also "double NAT" behind another router without switching to modem mode.

Like I said before, I'd find it highly unlikely that Virgin Media would go to the trouble (and potential risk) of using a back door into your router, just to stop you watching (I presume legal) videos?

I'm sure Virgin blocked me a day after watching my first cat video...

If they can block all of the porn and cat related content they may finally have enough bandwidth available to support their customers as they should...

Why would a ISP go to that trouble to access the router and manage your network. They would just do it their side. And no an ISP would not do this anyway.
