I'm having various errors, from unauthenticated requests for using some AJAX requests (which need authentication).
While I have clients from Belgium, the IP addresses match a IP in the form of
150.70.*.*, all are using Windows XP and IE 6 or IE 8.
When I do a lookup, I receive this: http://ip-lookup.net/index.php Which means that it originates from Japan and it's a static IP from trendsmicro.com, a security suite.
Any idea if I can blacklist this? I'd like to keep my errors close to zero. But this is one I can't solve without blacklisting the IP range.
What should I do and what does trendsmicro try to do when cloning the request?
