Well, I just checked out the website without avast protection and looked at the code (I don't care, I just have a test machine) and the only thing that I could see that might be telling avast that there is a malicious code was this:
document.writeln("You are being redirected to the forums.<BR>");
setTimeout("location.href='hxxp://forums.s3chromezone.com';", 5000);
I don't see any problem with that code though.
I'm not really sure what is setting avast off. If that site "hxxp://chromezone.s3graphics.com/" is actually the page that's giving avast problems, it must be a false positive. Unless of course the page that it forward or redirects to is the problem, then that's a different story. If there is, I didn't see it in the code of the redirected site either... "hxxp://forums.s3chromezone.com/phpBB3/"
I dunno... I'm stumped.
