Ive used internet explorer for a few years now and have never had any problems. The schools I have gone to and now attend also used internet explorer and they have never had any problems. I also use Macafee Security system which blocks all security problems. the security package I have includes antivirus, anti spam, anti hacker, antiabuse, and firewall. I got it at walmart for $49.99 and it tells me when I have a virus, quarentines it and removes it. it tells me when someone is trying to hack into my computer and shuts them out, does virus scaans on demand and as prgrammed, and doesnt allow any spamming computers send me anything. With all this theres no reason for me to worry. Besides that, microsoft does send updates and patches to my computer weekly that fixes any problems. My computer has a yellow arrow in the systems try that tells me when updates are available, I click on that and it tells me what the updates are for. I choose which updates I want to install. I am confident that I can continue using microsoft programs including IE with no problems at all.
