Problem with Trojan and EasyBlog

Hello I have had a problem the last week with the EasyBlog installed on the website. It has had a trojan virus attached to it every time I have got rid of it and its come right back and its only attaching to the blog this has been since the last software update you sent out. is there a version of EasyBlog that doesnt have viruses that I can re install onto the website beings that it is very important to the website as the Blog is the most popular thing on our site? I would like to get this fixed and back up and ruining by Monday.

I have had to completely uninstall EasyBlog from the site until I get answers from you as our host was going to black list our site and that just cant happen.

thanks
Vicky
