Looking more deeply into it, it seems that the Google bots found a link to another website that contained malware and flagged LB24-7 as supplying an infected page.
Most anti-virus progs refer to outside sources such as Google to maintain their list of infected sites.
The other website has now been listed as clean and has been un-flagged, but LB24-7 is still flagged as linked to the other website.
LB24-7 will have either remove the link, or get Google to remove the flag from their website too, even then it will take time for all anti-virus lists to be cleared.
You can add LB24-7 to your personal exceptions and gain access that way.
