Text on my website has chnged to advert links, HACKED?

Hello,
Since I have come back from holiday, I have notice that text in the descriptions had appeared as clickable links to SPAM. How do I remove this?
Here is an example... http://craftjam.co.uk/index.php?main_page=product_info&cPath=11&products_id=496 the word, Name necklace becomes a link after loading.

I also noticed that this has happened inside my admin when I go to edit products.

Thanks

I don't see the links, which suggests it's something that has been installed on your local computer. Try cleaning your browser cache and running your anti-virus software.

I am currently running the scan, however that one doesn't seem to appear any more, the one that is there now is on the same page and is in the rainbow heading that says Home :: WORD NECKLACES :: 2 part laser cut engraved **heart necklace ** they appear about 20 - 30 seconds after the page loading.

If that doesn't work, do you have any other suggestions?

Thanks

FOUND IT! It wasn't on the scan, it was a piece of software called yontoo that had installed its self. It was listed in uninstall in control panel.

Thanks

Now ask yourself how it got on there. Often that kind of junk is installed when someone downloads and installs some sort of 'free' software, especially games.
