InterScan Web Security Suite - iwssd.exe 100%cpu load.

IWSS 3.1 build 1158 on Windows 2003 Standard with SP2.

In working hours the service uses over 90 % CPU, but in the evenings (when there are just a few home office users connected) it uses between 10 - 40 % of the CPU. This problem occurred suddenly, without any extra load to the server. This makes internet surfing slow. The server functions only as a proxy, not url-blocker.

Nothing interesting in the eventviewer, have tried restarting the server without any luck.

It could be the newer bug that was announced: https://bugzilla.redhat.com/show_bug.cgi?id=484370 

When did the problem start, could you paste some of the logs here?

Depending on the site that you are trying to browse, say for example, a video streaming site or a website which has a lot of graphics to display. All of these will be scanned by your IWSS. You may want to enable "deferred scanning" found at https>virus scan global policy>virus scan rule then check if there will be any difference.You may also skip scanning of specific mime types , say video mime types , etc., You may also want to make sure that your IWSS is loaded with the latest patch which you may download from this site: trendmicro.com/download.

Thanks for reply guys!
rbgCODE: Wrong link?! The problem started about 2-3 weeks ago. Eventviewer logs you want?
SSharma: I cant find that option in the admin console, IWSS is loaded with the latest patch.

Removed virus scan and web reputation, that did the trick. Didn't need it.
