Unexpected behaviors and failures in Internet Explorer with McAfee Host Intrusion Prevention installed


Hi everyone!


IE Support is seeing a huge influx of issues with weird IE behaviors and failures coming in over the last two days.  We are seeing IE crashes, IE simply unloading from memory, and even script errors on web application that have been working in the past without issue.  Currently, we are only seeing these errors with Internet Explorer 7 and 8.


The issue appears to be related to a recent signature update to McAfee’s Host Intrusion Prevention software that was released on July 14, 2009.


If you are seeing these kinds of behaviors with Internet Explorer since in or around the July 14th, 2009, we recommend that you review the details outlined in this McAfee KB article:

Our understanding is that a signature update has already been released to resolve this issue.  However, if you need further assistance from McAfee technical support in getting the signature update, you can contact them using the information located here:

More information:  You can continue to browse in a limited capacity by starting Internet Explorer in No Add Ons mode by using the shortcut located under All Programs | Accessories | System Tools until you update the affected signature file:

There is also a command line option you can use as well.  From a command line window you can using the below option:

Once you hit enter, IE will load with no Add Ons within the IE process:

    It seems that ever since I downloaded IE 8 during the course of being on a website, the screen will go all black and then a message appears in a small white box that flashes "Auto Adjustment" the screen goes black again and then another small white box appears and flashes "Auto Finished".  This can go on for about an hour.  Sometimes it is constant, sometimes there are several minutes before it starts flashing again.  Not sure if this has anything to do with IE 8 or has anyone else experienced this.  Thanks
