It would help to know which version of Windows and which version of Internet Explorer. And the Exact wording of the error message. You can frequently search exact error message wording and instantly find a fix. If XP you might go into 'Computer Management' and look at the 'Event Viewer' error logs. Sometimes that will show the error and supply a link to a suggested fix. If you don't know how to access 'Computer Management' Click help off the Start Menu. Before doing too much perhaps try going to Control Panel and Internet Options - Clear IE cache & offline files as well as clear the History too. If you have a spyware program, you might want to run it also. One thing that can cause that IE must close message is a firewall... have you added a new firewall ? You can only have one firewall running at a time.

well those toolbars come with many many programs if you do not read carefully when doing installs or updates including java, flash, and IE, many of them, in fact there is a hall of shame at COU forum listing all of the programs that now include pre selected toolbars in their install, it has nothing to do with the browser you use to do the download or install it has to do with watching what is pre checked when doing your updates or program installs and un checking any for things like toolbars. I have had to clean tons of toolbars off of peoples computers too who had never heard of firefox, only had IE. I tell people to add a second browser because it is a very good idea to always have at least 2 on the pc because as we all know IE can and does fail then leaving them no way to access the internet. Whether they select firefox, chrome or opera, it does not matter but firefox is the best known so when asking for help they will find more people that are familiar with it. All browsers have their pluses and minuses none are perfect and I have never seen anyone here say any one browser is perfect. the point to make to people who have loaded up their pc with toolbars, why this is happening to them, is to watch what they are doing! Pay attention to every single line when doing any type of install. And do not let it add unwanted items, if they are not told how it happened it will happen again. I direct them to this list Installers Hall of Shame (Unwanted add-on)

If they did that they would have a TON of windows updates to do plus likely all 3 service packs to deal with. Any of those items you listed try doing a google search for them and you will quickly find out what they belong to, or use a program like free start up lite by the makers of malwarebytes. StartUpLite avg= your antivirus is AVG? you do not want to stop that for sure. you can use a process library to find what each one is and does, what ever you do, DO NOT use a registry cleaner! if this is a dell then the dsca is a dell file C:\Program Files\Dell Support Center\gs_agent\custom\dsca.exe DSCA is Dell's remote-support app. If you're relying on Dell's remote-desktop support, do not delete it. but it does not need to be in your start up list. msseces.exe (Microsoft Security Essentials) are you using both AVG and Microsoft Security Essentials on your pc for Antivirus? if so you need to fully remove one of them you should only run one full time AV at a time that will cause conflicts. smax4pnp.exe (SoundMax controls) you can look up the rest of them there at the pcpitstop library if you want. another good free program that can help you with this kind of stuff is winpatrol WinPatrol

Hi Jo, I'm no mac expert but it looks like Windows stop making Internet Explorer around version 5 for Macs. The only way I see you using Internet Explorer is you got to buy a full version of Windows and use something called "boot camp" from Apple.You basically end up with a dual boot machine.The best of both worlds.The downside is you got to pay for the Windows disk to get Internet Explorer. Hope this helps ya. Here is a link that might be useful: Apple boot camp
