Yes, it has been happening for some time and I too, often can't even open the site !

Not good for visitor numbers and after reading the other comments here, i ran a multiple security check [I have an arsenal] on my PC before re-visiting to make sure my computer is squeaky clean, logging out and re-running the security sweep.

Sure enough, this site is depositing a little 'uninvited guest' onto my PC and I don't mean the friendly cookie. Nothing serious, but enough to be down right annoying!
