How do I beat this hack/exploit

[Zond2]

Help!
When google-ing one of our events what comes up is an disturbing collection of nonsenese and un-related items
with our websites addy at the bottom. When I click on the entry I do end up at the website so what is going on?
This AM a search returns:

Sunday 01st 2009f February 2009 12:51:44 AM - [ Translate this page ]GOOGLE THIS SITE MAY HARM YOUR COMPUTER [snip]

What is going on and how do I remedy this?

Welcome to the forums Zond2,

As you might have noticed already due to it's wide reporting, (see this thread [webmasterworld.com]), the problem was due to human error in Google's system and has now been remedied.

[Zond2]

Alas while the "this site may harm you computer" may be gone the rest on the unrelated dreck that appears in the description (and is not found in the HTML code of the site ([snip])) still appears. This has been happening for some time and what is listed in the description changes from day to day

Zond2, if you could have a quick look at the terms of service [webmasterworld.com] regarding the posting of specific URLs it would be appreciated :)

Having looked at the Google cache of your site, it does indeed display the text you mentioned, albeit the cache is totally different from your homepage.

Do you recognise the contents of the cache?

[Zond2]

OOPs!
No I do not recognize the contents of the cache

[brotherhood of LAN]

In that case you may want to consider that your site has been compromised somehow, and that alternative content is being served whenever google visits your site (because you didn't put the content there, and google has a cache of it claiming it's your site).

I'm not aware of any other Google technical issues so it's a possibility you might want to check out...

I know the topic has been discussed on WebmasterWorld before so I'll post a thread link if I can find one.

This recent thread [webmasterworld.com] describes a hack that is being put on sites to divert search engine spiders (only) to the hacker's sites, resulting in "strange" search results (among many other bad effects).
