Getting redirected when connected to home wifi

[ng93]

Having a strange problem, whenever I try to connect to a specific subdomain on a domain i own via my home wifi I get shown a site for a helping hands charity, which I've never seen before. Now I have neither any subdomains or charity content on it (it's pretty much empty). At first I assumed virus, but it also occurs on my Nexus 4 and PS Vita. Then I thought it was a problem with the host, but when connecting via 3G the site doesn't exist (which is what should happen). Is it possible that it's to do with my connection or router? I'm on BT infinity using the standard home hub.

Thanks,

Try using another DNS server like googles or OpenDNS, see what happens.

Thanks, I didn't get to try that last night, although I did reboot the router and still got redirected, so then turned off both the rooter and modem for 10 mins, tried again this morning and no more redirect. So possibly just a caching issue?

Still doesn't explain why it happened in the first place though, could a virus have caused this?
