You can go to your control panel add remove programs and remove all that extra yahoo stuff like the toolbar etc. IE is by Microsoft no one else makes IE period, there are add ons that can be added to it but if you have IE8 you have the Microsoft IE8. Deleting the extra yahoo stuff will not affect your yahoo email at all you can still go to yahoo and sign into your yahoo mail account, you can do that from any pc anywhere. I totally agree in downloading and installing firefox or an other browser so should that one stop working you still have a way to get online. I personally use firefox, it is super easy to do just go to the download site, choose to download the windows version, it will install, in the process it will ask if you want to import your settings from IE just say yes to all and it will set up firefox exactly as you have your Ie with all your bookmarks and home page etc. It will ask if you want to make it default you can say no that can be changed any time. Then once it is done and installed anytime you want to use firefox to go online just click on the firefox icon on your desktop or tray, you can go back and forth using IE and firefox and can even use both at the same time. Firefox has a lot of great add ons for it that I love. Should you need the download link to re-install IE8 here is where to go.

So for firefox use firefox to download the firefox version of flash, install, for IE go with it get the ie version and install. I generally get the flash at filehippo just search for non ie flash on Google. I would suggest adding the adblock plus add on with the easylist subscription to block the ads which will help speed page load quite a bit. Definitely make sure that your adobe products as well as java are fully updated and it is essential to remove the old versions just having them on the pc leaves the security issues there. Go with each browser and update.
