Like it or not, IE is absolutely required for some programs in Windows. I think it might well be the only coherent way to download updates for Office. The Windows help system has been converted to a form of HTML file which requires IE. Office is hardwired to use IE for certain things, and so on.
You shouldn't try and disable IE, just not use it unless you have to (e.g. for Windows or Office Update).
I'm not totally literate in these situations, So I really need help with this. I've been trying to migrate permanently from IE to Mozilla Firefox, due to being bombarded with HUGE amounts of spyware and trojans, but it's been tough going. I found a procedure that supposedly disables IE, but I don't think it's working. I recently set up a free version of the ZoneAlarm firewall and lock it when I'm not online. When I unlock it, I have to restart my system, sometimes 2 or 3 times, and I get popups with IE in the headers. I've locked out IE in the ''programs'' list and have given full access to Firefox, but it doesn't help. Even with the firewall, I still find a lot of spyware when I do a search with AdAware SE. I also have the free version of AVG virus protection installed. I've read about LiteXP and have seen a posting about other free solutions that didn't list specific names. I'm trying to stay on a budget and protect my system from the ravages of IE at the same time. I'm running XP on a HP Pavillion mx75 and I access by cable modem. Are there inexpensive or free solutions for a non-techie like me?
