Just happenned when I installed mcafee antivirus. Then when I turned on mylaptop, just pop out that Internet explorer is currently running with add-ons disabled. I tried to follow all the instructions like..go to manage add on, enabled all program and re start but still the problem is there..

My suggestion to remove both McAfee and Norton, they slow down the PC to a crawl. Also they bring all sorts of toolbars and unwantedness.

The free and light use antivirus is the one built into Windows, or if you are rocking Windows 7, Microsoft security essentials. Another one would be malwarebytes as a second layer of defense.

1. Does the behavior persist if you start IE in No Add-ons mode?

Explorer (No add-ons).

2. Does the behavior persist if you Reset IE Advanced settings (RIES)?

3. What anti-virus application or security suite is installed and is your
subscription current? What anti-spyware applications (other than Defender)?
What third-party firewall (if any)? Were any of these applications running
in the background when you installed IE8?

4. Has a(nother) Norton or McAfee application ever been installed on this
machine (e.g., a free-trial version that came preinstalled when you bought
it)?

Open the antivirus setting menu and disable the things that you dont need. IE crash is a common thing, mine also crashes. Firefox will be the best, install it.
or contact technical support.

Sometimes the best solution is to save to disk the important things and just reinstall everything. 

Hey tjchan92,

Unless you personally installed the "AntiVirus2009" program or this other application, what you may be encountering are either misleading plug-in applications or your computer may currently have spyware installed. Generally, one of the best ways to determine what these programs are is to run a system scan using the full version of an anti-virus/spyware program such as Norton AntiVirus or McAfee VirusScan. Should you choose to do so, you’ll want to make sure you’re using the latest virus and spyware definitions available since new threats surface all the time.

Please keep in mind that I only mention Norton & McAfee as examples. These are by no means the only anti-virus/spyware programs available, and are simply among the most easily-recognizable brands available through many major retailers.

Alternatively, you may be able to minimize how often these windows appear by adjusting your internet settings. Doing so will typically block pop-up windows and banner ads from websites you visit, and can often be done by changing your Internet Explorer privacy setting to "Medium-High" or "High” through the “Tools” menu.

Hope this helps you out.

Sincerely,
Aaron
