I posted a project the other day for a VPS that has been hijacked (if that's the right term). I had a guy fix it - but the problem is either still there - or it came back.
You mentioned an OS reload; will this effect the cart? It is a very large and complex cart - and I can't risk losing that.
The site is [login to view URL] - although it seems like maybe its just the cart that is infected at the moment. Let me know what you think...
