Hidden spam on my website

Hi guys,

there’s a million forum posts close to this, but none that I could see that matched it exactly. I’m using the Gridlocked WordPress theme for my website

A couple of weeks ago my hosting company contacted me to say that spam had been sent out from the mail on my site – which I never use – and so they’d shut the site down while they sorted it. Very shortly after that it was put back up and the site looks fine, but if you google the URL it comes up with a lot of viagra spam as the description. This also happens if you post links to the site on social networking sites (which I need to do a lot).

My host reckoned the spammers got through via a dodgy plug-in and said if I removed the plug-in it would fix it. I did, but the spam is still there somewhere.

I’ve been trawling through the code but can’t find any trace of it. Any suggestions? (I’m not very skilled with coding I’m afraid)
