IE8 issues if immunization by Spybot-S&D is enabled
There are reports that IE8 will not start fast if user’s system is immunized using Spybot S&D. I able to reproduce this in Vista and XP.
There is report of high-CPU usage when Spybot –S&D immunization is enabled. I able to reproduce this in XP.
There is also report that IE8 will not load fast or it will hang if restricted sites exists in IE Restricted Sites zone, e.g. using IE-SPYAD and I able to reproduce this also in XP and Vista.
Time for the authors to check their protection tools for IE8 compatibility. For now, users who want IE8… should disable the immunization and IE-SPYAD. For users who prefer the protection over IE8, stay first with IE7.

Update1: My friend Todd (author of ZonedOut) suspect that it's the new feature of IE8 that is causing the issue. I read around LOL and then noticed that new thing, LCIE. More here.
Update2: IE Team confirmed the above problem exist IF there are many domains in the restricted sites. See comment of IE Team, Eric Law a at their blog.
