Malware listing

Hi,
Every time I try to access this site (xerte.org.uk), my internet filters light up like a Christmas tree - both my Web of Trust and Virgin Media filters flag your site as containing malware.
Tracing things back to source, www.surbl.org seems to think your site has been hacked and is vulnerable to further hacking.
Given that I am installing XOT on my server, please can you give me some background / reassurances here?
Thanks
Stephen Parry

Thank you for the heads up. We'll look into it.
Nevertheless, this is a warning about the software we use to run the community website, not about xerte itself.

Hello,
I've got same problem with myWOT.

But also with Clam antivirus. I've installed Xerte online toolkits. It seems to find a vulnerability into
/xerte/XMLEngine.swf: Swf.Exploit.CVE_2014_0581 FOUND

What can I do?
