Avast! Anti Virus - False trojan warning

I recieved the warning bout Avast giving false virus warnings,so I went to Avast link Proboards gave in heads up.
I askedd about this and could they fix it.Here is their reply back to me:
This page seems to be <suspicious> 1 suspicious inline script found.
www.UnmaskParasites.com/security-....e.proboards.com

partner.googleadservices.com/gampad/google_service.js
Malicious software includes 8 scripting exploit(s), 2 exploit(s), 1 trojan(s). Successful infection resulted in an average of 1 new process(es) on the target machine.

Now,what do I do? Is this your baby or mine?
